what is the solution to 7.5d=2.5d
Answer:
d = 0
Step-by-step explanation:
To find the solution to the given equation, we must solve for d in the equation.
7.5d = 2.5d
Subtract 2.5d from both sides.
5d = 0
Divide both sides by 5.
d = 0
So the solution to the equation would be d = 0.

Step-by-step explanation:
Suppose Ax = b has a solution. Explain why the solution is unique precisely when Ax = 0 has only the trivial solution. Choose the correct answer. 0
A. Since Ax = b is inconsistent, its solution set is obtained by translating the solution set of Ax-0. For Ax-b to be inconsistent, Ax = 0 has only the trivial solution.
B. Since Ax-b is consistent, its solution set is obtained by translating the solution set of Ax-0. So the solution set of Ax = b is a single vector if and only if the solution set of Ax 0 is a single vector, and that happens if and only if Ax 0 has only the trivial solution.
C. Since Ax = b is inconsistent, then the solution set of Ax = 0 is also inconsistent. The solution set of Ax = 0 is inconsistent if and only if Ax = 0 has only the trivial solution.
D. Since Ax = b is consistent, then the solution is unique if and only if there is at least one free variable in the corresponding system of equations. This happens if and only if the equation Ax 0 has only the trivial solution.
Answer:
B. Since Ax-b is consistent, its solution set is obtained by translating the solution set of Ax=0. So the solution set of Ax = b is a single vector if and only if the solution set of Ax= 0 is a single vector, and that happens if and only if Ax 0 has only the trivial solution.
Step-by-step explanation:
the answer to the question is answer B. and here is the explanation below
let us imagine that the equation ax = b has a solution
now our goal will be to show that the solution of ax =b when ax = 0 has only trivial solution.
ax = 0 is homogenous
if this equation was consistent for b, we define
ax = b to be a set of vector that has the form
w = m + gh(h is a subscript)
gh is a solution of ax = 0
from what we have above, ax=b is in the form ofw= m+gh
with
m = solution of ax=b
gh = soulution of ax=0
ax = 0 has only trivial solution
gh = 0
with gh = 0
ax=b is w=m
so ax = b is unique.

If (s -a) = 5cm, (s -b) = 10cm, (s -c) = 1cm then find s
Answer:
s = 1/3 (a + b + c + 16)Step-by-step explanation:
Given If (s -a) = 5cm, (s -b) = 10cm, (s -c) = 1cm s = ? SolutionAdd up the 3 equations and solve for s:
s - a + s - b + s - c = 5 + 10 + 1 3s = 16 + a + b + c s = 1/3 (a + b + c + 16)Which is the solution to the equation 8.25 + one-fourth w = 10.75? Round to the nearest hundredth if necessary.

Answer:
10
Step-by-step explanation:
[tex]8.25 + \frac{1}{4} w = 10.75[/tex]
Subtract 8.25 from both sides.
[tex] \frac{1}{4} w = 2.5[/tex]
Multiply by 4 in both sides.
[tex]w = 10[/tex]
Answer: 10
Step-by-step explanation:
Subtract 8.25 from both sides.
Now have 1/4w=2.5
Multiply both sides by 4.
Now you have w=10
One-eighth of a bookstore's magazines are sold on a Friday. If 1/4 of the remaining magazines are sold the next day, what fractional part of the magazines remains at the end of the second day?
Answer:
5/8
Step-by-step explanation:
These types of problems only require you to know how to make fractions similar in denominators (or the GCF).
If one-eighth of the store’s books are sold and then the next day 1/4 of the store’s books are sold then we simply only need to add the fractions and minus them from 1.
To do this we need to make 1/4 into an eighth. The GCF between 4 and 8 is 8 because you can multiply 4 by 2 to get 8, therefore you need to multiply 1/4 by 2/1 (or just 2). 1/4*2/1= 2/8.
Now that we know what 1/4 is in eights we want to add 2/8 to 1/8 which would be 2/8+1/8=3/8. Now we minus 3/8 from 1 to get our remaining amount of storage. Now all we need to do is think how much eighths is one, to do this just think what divided by 8 is one, which would be 8. 8/8=1. Therefore, 8/8-3/8=5/8.

Given: Angle1 and Angle2 are supplements, and Angle3 and Angle2 are supplements.
Prove: Angle1 Is-congruent-to Angle3
Three separate angles are shown. They are labeled 1, 2, 3 from left to right.
Complete the missing parts of the paragraph proof.
By the definition of
angles, the sum of the measures of angles 1 and 2 is 180 degrees. Likewise, the sum of the measures of angles
is 180 degrees. By the
property, mAngle1 + mAngle2 = mAngle3 + mAngle2. Subtract the measure of angle
from each side. You get mAngle1 = mAngle3, or Angle1 Is-congruent-to Angle3, by the definition of congruence.
By the definition of supplementary angles, the sum of the measures of angles 1 and 2 is 180 degrees. Likewise, the sum of the measures of angles 2 and 3 is 180 degrees. By the substitution property, m1 + m2 = m3 + m2. Subtract the measure of angle 2 from each side. You get m1 = m3, or m∠1 = m∠3, by the definition of congruence.
What are supplementary angles?Supplementary angles are angles whose measures sum to 180°.
m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
substitute m∠2 + m∠3 for 180° in equation (1)
(substitution property)
m∠1 + m∠2 = m∠2 + m∠3
subtract m∠2 from each side
m∠1 = m∠3 (congruent angles)

2. Rolling an odd number on a number cube (dice) containing numbers 1 through 6 is as likely and not .
3. Randomly picking a white card from a bag containing all red cards is unlikely .
4. Choosing a blue marble in a bag of marbles with 10 blue marbles, 2 white, and 1 red is certain .
1. Choosing a red crayon from a box of 24 different colored crayons, including red crayons is likely.
Explanation: Since the box contains red crayons and the total number of crayons is not specified, it is likely that at least one red crayon is present.
2. Rolling an odd number on a number cube (dice) containing numbers 1 through 6 is as likely as not.
Explanation: A standard six-sided dice contains three odd numbers (1, 3, and 5) and three even numbers (2, 4, and 6). Therefore, the probability of rolling an odd number is the same as rolling an even number, making it as likely as not.
3. Randomly picking a white card from a bag containing all red cards is unlikely.
Explanation: If the bag contains only red cards, there is no possibility of picking a white card. Therefore, it is unlikely.
4. Choosing a blue marble in a bag of marbles with 10 blue marbles, 2 white, and 1 red is certain.
Explanation: Since there are 10 blue marbles and the total number of marbles is not specified, it is certain that at least one marble will be blue.

. At Medina Middle School, 28 out of 350 the students ride bikes to school. At Rachel Carson School, 40 out of 500 students ride the bikes to school? Do both schools have the same rate? Answer:
2. According to the school survey 72 out of 400 students at Adams High School speak Spanish. If the rate is the same at Francis Lewis High School with the total population of 250, how many students speak Spanish at Francis Lewis High School? Answer:
3. Marco makes $24 for 6 hours of chores and Olivia makes $36 for 8 hours of chores. Are they getting the same rate of pay? Explain your reasoning.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the questions:
1.)
Medina schools :
Number of students = 350
Number who ride to school = 28
Rate = 28 / 350 = 0.08
Rachael Carson schools :
Number of students = 500
Number who ride to school = 40
40 / 500 = 0.08
Yes, they both have the same rate
2)
Adams high:
Number of students = 400
Spanish speakers = 72
Rate = 72 /400 = 0.18
Francis Lewis :
Number of students = 250
Since rate is the same,
Hence,
Number of Spanish speakers = 250 * 0.18 = 45 students
3.)
Marco Earns $24 for 6 hours worked
Olivia makes $36 for 8 hours worked
Marco's rate of pay :
Amount earned per hour : $24 / 6 = $4
Olivia's rate of pay :
$36 / 8 = $4.5
They do not earn at the same rate

a whisper volume as a room that allows two people to stand on opposite side of the template luckily shape long and hear each other's Whispers. The locations at which they can hear one another are the foci of the ellipse. If the room has a major axis 122 ft and a minor axis of 22 ft, how far apart, in feet, are the two people?
Answer: 120 ft
Step-by-step explanation:
The Ellipse equation is: [tex]\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1[/tex] where
(h, k) is the center"a" is the horizontal radius"b" is the vertical radiusc is the distance from the center to the foci: |a² - b²| = c²Given: horizontal diameter = 122 → horizontal radius = 61 = a
vertical diameter = 22 → vertical radius = 11 = b
Foci (c): 61² - 11² = c²
3721 - 121 = c²
3600 = c²
±60 = c
Let (h, k) = (0, 0)
Then the foci are located at -60 and +60.
The distance between them is 60 + 60 = 120
