Do you have 135$ in a savings account and save $12 per week your friend has $95 in a savings account and save $20 per week how many weeks will it take for you and your friend have the same balance?
Answer:
5 weeks.
Step-by-step explanation:
If w is the number of weeks, apply algebra.
So think about what would be the total money saved, or the same thing as the Money in saving account + Money saved per week × Number of weeks
For you, this would be 135 + 12w
For your friend, 95 + 20w
So then, 135 + 12w = 95 + 20w
1) 135- 95 = 20w - 12w
2) 40 = 8x
3) X= 5 (8 times 5 is 40)
Therefore, it will take 5 weeks for you and your friend to have the same balance.

Answer:
5
35
56
Step-by-step explanation:
8 x 7 = 56
Subtract 21 (3x7) from 56 (8x7) to get 35
Divide 35 by the given value 7 to get 5
5 x 7 = 35
35 + 21 = 56
James types 50 words per minute. He spends 20 minutes typing his homework. What is the domain of this situation.
A. {all numbers between and including 0 and 50
B. {all numbers between and including 0 and 20}
C.{all numbers between 0 and 50}
D. {all numbers between 0 and 20}
Answer:
B. {All Numbers between and including 0 and 20}
Step-by-step explanation:
This is a graph of: Words (along y-axis) against minutes (z-axis)
As shown in attached graph sketch; the slope of this graph is 50 words per minute.
So the domain of this graph is all numbers between and including 0 and 20.

i need help please asap.
Answer:
x = 31
Step-by-step explanation:
8 + 2x - 12 = 58
Combine like terms to make math easier:
-4 + 2x = 58
Then do math:
(-4 + 4) 2x = 58 + 4
2x = 62
2x/2 = 62/2
x = 31

A linear pair sum to 180° , then
x - 30 + x + 76 = 180 , that is
2x + 46 = 180 ( subtract 46 from both sides )
2x = 134 ( divide both sides by 2 )
x = 67
Then
∠ 1 = x - 30 = 67 - 30 = 37°
∠ 2 = x + 76 = 67 + 76 = 143°
-------------------------------------------------------

Since T is the midpoint of SU , then
ST = TU , that is
5x = 3x + 32 ( subtract 3x from both sides )
2x = 32 ( divide both sides by 2 )
x = 16
Then
ST = 5x = 5(16) = 80
TU = 3x + 32 = 3(16) + 32 = 48 + 32 = 80
SU = 5x + 3x + 32 = 8x + 32 = 8(16) + 32 = 128 + 32 = 160
An object is moving at a speed of 3 kilometers per hour. Express this speed in feet per minute. Round your answer to the nearest whole number.
Answer:
164 feet per minute
Step-by-step explanation:
3 kilometers is ~9842.52 feet
Since it moves 9842.52 feet per hour, we can just divide that number by 60 which gives us 164.042 feet. Rounded it's 164 feet

Zina solves a system of linear equations by elimination and finds that the solution to a system is (2, 2). One of the equations is a + b = 4. Which answer could be the other equation?
a + 3b = 4
2a + 2b = 2
4a + 4b = 8
a + 3b = 8
Answer: a + 3b = 8
Step-by-step explanation:
a + b = 4 is true, since (2,2) works: 2 + 2 = 4
Try (2,2) in the options to find which one is true for (2,2):
A) 2 + 3*2 = 4? No.
B) 4 + 4 = 2? No.
C) 8 + 8 = 8? No.
D) 2 + 6 = 8? YES.
Therefore, a + 3b = 8 can be another valid equation.
Answer:
D. a + 3b = 8

A group of 123 students went on a field trip to
collect seashells. If the students collected 15 shells
each, how many shells did they collect?
Answer:
8.2
Step-by-step explanation:
If each student in the group collected 15 shells, we know that there are 123 students on the field trip, so we can take 123 and divide it by 15 to get 8.2 or 41/5.

For the figure shown on the right, find the value of the variable and the measures of the angles.
X=
Step-by-step explanation:
the sum of all angles in a triangle is 180 degrees.
so,
x + (x - 6) + (2x + 34) = 180
x + x - 6 + 2x + 34 = 180
4x + 28 = 180
4x = 152
x = 38 degrees
x - 6 = 32 degrees
2x + 34 = 110 degrees
After 1 year, the value of a car decreases by 19%. The car is now worth £3078. What was the value of the car originally?
Answer:
3800
Step-by-step explanation:
Variables:
O - Original cost
N - New cost
c - change factor
Step 1:
Recognize that if something decreases by 19%, it is worth 19% less
This means that the new price, fractionally, is 100% - 19% = 81%
So we can use c as 0.81 (81/100)
Step 2:
Write an equation to represent what is happening
N = O * c
Step 3:
Sub in what we know
3078 = O * 0.81
Step 4:
Rearange and solve
O = 3078 / 0.81 = 3800
18 decreased by a number
Answer: 18-(x)

How many different 6-digit license plates are possible if the first 3 digits can be any letter and the last 3 digits can be any number?
A. 108
B. 17,576,000
C. 128
D. 15,725,000
Answer:
B
Step-by-step explanation:
every position on the license plate is independent from the others.
so, for each position we have the full choice of all possibilities.
there are 26 letters in the alphabet. and there are 10 different single numeric digits.
so, for the first position we have 26 possibilities. as we have for the second and third positions.
the means for each option for the first position we have 26 choices for the second.
that is 26×26.
then for each given choice of the first 2 positions we have 26 choices for the third position.
that is then 26×26×26 possibilities.
for each of the given choices of the first 3 positions we have 10 choices on the fourth position. and then on the fifth and the sixth positions.
the makes altogether
26×26×26×10×10×10
even without calculator I know it must be B, because the number of possibilities must end with 3 "0"s (due to the 10×10×10).
and the main number block must end with a "6" due to 26×26×26, which means for the last position we only need to consider 6×6×6. 6×6 = 36 ending in a "6". and that again multiplied by 6 is again 36 ending in a "6".
so, 26×26×26 has to end with a "6". that gives us B.

Jillian simplified the expression
7+3 . (10 – 6)2 in the following way: 7+3 . (10 – 6)? 2. 7+3. (4) 7 + 3.16 10 - 16 160
A: Explain, using complete sentences, what Jillian's error was.
Part B: Show how the expression should have been simplified using a similar format.
Error in step [tex]10 \cdot 16[/tex] (3 times 16 should be multiplied first )
Steps to simplify
[tex]7+3 \cdot (10-6)^2\\7+3 \cdot (4)^2\\7+3 \cdot 16\\7 \cdot 48\\ 55[/tex]
Given :
Jillian simplified the expression [tex]7+3 \cdot (10-6)^2[/tex]
Steps :
[tex]7+3 \cdot (10-6)^2\\7+3 \cdot (4)^2\\7+3 \cdot 16\\10 \cdot 16\\160[/tex]
Explanation
Lets analyze step by step to find out the error.
Use order of operation PEMDAS
Start with parenthesis , exponents , multiply and divide , add and subtract
Jillian simplified the parenthesis first
Second step is correct
Next exponent is simplified
In the fourth step , 7 and 3 are added before multiplication
10 times 16 is not correct
As per PEMDAS, we need to multiply first and then add 7
Error is step [tex]10 \cdot 16[/tex]
[tex]7+3 \cdot 16\\7+ 48\\Add \; 7\\55[/tex]

I’m sorry about that. I never would have imagined myself choosing those two over you.
