Answer:
30=3x
so divide 30 by 3 and you'll get x
Answer:
10
Step-by-step explanation:
You equate. The two angles are equal. The figure is called vertically opposite.
Vertically opposite angles are equal.
3x = 30 Now you divide by 3
3x/3 = 30/3
x = 10
And 10 is your answer.
If a swimmer swims 35.4 yards in 2 minutes, how many meters will s/he swim in 60 seconds?
Answer:
17.7 yards. 35.4 yards/2 minutes (120 seconds) divided by 2 = 17.7 yards/1 minute (60 seconds). hope this helps

NUMBER SENSE Determine which number is greater and which number is farther from 0.
-3.25,
7
#2 i
The greater number is 7
The number farther from O is
Explain your reasoning.
B
1
U
!!!
T
T.
Step-by-step explanation:
Ok...so yes the greater number is 7 but 7 is also the number farther from zero because when the positives and negatives are ignored, it takes 7 unit spaces to get to 7 whereas it only take 3.25 to get to the negative, making 7 farther from 0 than -3.25.
Answer:
This is wrong .
Step-by-step explanation:
Simplify the following expression:
(−1/8 + 2/5) + 3 3/5 (the / mean its a fraction! )
A. 3 3/40
B. 4 1/8
C. 3 7/8
D. − 3 13/40
Answer:
2 21/40
Step-by-step explanation:
First, you take the fractions in the parenthesis and make the denominators alike by finding the least common multiple. Once you've done that you can add them together and then add the outer fraction. When adding the outer fraction, you need to make it into an improper fraction. I hope this helped! :)
10. Dan explained that the middle tower is always the same number as the step number. He
also pointed out that the two arms on each side of the tower contain one less block than
the step number

Create an equation that fits Sarah's way of seeing the relationship.
The given pattern is an illustration of a linear equation. The students' equations are:
Dan's: [tex]n = s + 2(s - 1)[/tex].Sally's: [tex]n = 3s - 2[/tex]Given that:
[tex]n \to[/tex] number of tiles
[tex]s\to[/tex] step number
See attachment for the pattern, that is being analyzed by the students.
Dan
For each step, the number of tower is the same as the step number.
This means that:
[tex]n \to s[/tex]
2 arms contain one less block means: 2 x (s - 1) blocks for both arms.
So, Dan's equation is::
[tex]n = s + 2 \times (s - 1)[/tex]
[tex]n = s + 2(s - 1)[/tex]
Sally
First, we calculate the slope (m) of the table
[tex]m = \frac{n_2 - n_1}{s_2 - s_1}[/tex]
So, we have:
[tex]m = \frac{4-1}{2-1}[/tex]
[tex]m = \frac{3}{1}[/tex]
[tex]m =3[/tex]
The equation is then calculated using:
[tex]n = m(s - s_1) + n_1[/tex]
This gives:
[tex]n = 3(s - 1) + 1[/tex]
Open bracket
[tex]n = 3s - 3 +1[/tex]
[tex]n = 3s - 2[/tex]
Hence;
Dan's equation is: [tex]n = s + 2(s - 1)[/tex]
Sally's equation is: [tex]n = 3s - 2[/tex]

Answer:
it varies between different situations
Step-by-step explanation:
the person could be very lazy and just dot down whatever they feel like or could take their time with the assignment an get a fairly god grade. on a four choice yes the typical score would be 70 and for a two choice test It would be around 50 depending on the amount of questions and whether the "Jimmy" gives a d4mn :)
So I have this equation after solving a question:
-a = 6
So my question is that will the minus at the position of a move to 6 turning it into -6?
Answer: any number or variable adding or subtracting when moved to the other side of the equal sign changes sign. Also you can change all the signs in both sides of the equation. so -a = 6 is the same as a = -6 or -6 = a.

what are the coordinates of the point on the directed line segment from(-7,-9)to (5,6) that partitions the segment into a ratio of 2 to 1?
Try this solution, note a) the suggested way is not the only one, b) the suggested solution is for segments AC:CB=2:1 only.
1) if the point A is (-7;-9), the point B is (5;6) and C is required point, then
2) the coordinate 'x' of the point C is:
[tex]X_C=X_B-\frac{X_B-X_A}{2+1}=5-4=1;[/tex]
3) the coordinate 'y' of the point C is:
[tex]Y_C=Y_B-\frac{Y_B-Y_A}{2+1}=6-5=1;[/tex]
4) the required coordinates are (1;1)
To take a taxi, it costs $3.00 plus an additional $2.00 per mile traveled. You spend $20 on the taxi. How many miles did you go?
Answer: 8.5 miles
Step-by-step explanation:
Given information
Base fee = $3.00
Fee per mile = $2.00
Distance = x
Total money spend = $20
Set equation
3 + 2x = 20
Subtract 3 on both sides
3 + 2x - 3 = 20 - 3
2x = 17
Divide 2 on both sides
2x / 2 = 17 / 2
[tex]\boxed{x=8.5}[/tex]

Pls help I’ll give you 35 points Sina's goal is to exercise a
mean of 45 minutes per
day for one week. She
exercised 35, 40, 37, 42,
45, and 50 minutes for six
days. How many minutes
must she exercise on the
seventh day in order to
reach her goal exactly?
Answer:
26 minutes
Step-by-step explanation:
Since the mean is the average of all the number, we need to reach a total of 315 minutes for the entire week.
[tex]35+40+37+42+45+50=\\75+40+37+42+45+50=\\115+37+42+45+50=\\152+42+45+50=\\194+45+50=\\239+50=\\289[/tex]
Since 315 - 289 = 26, she needs to exercise for 26 minutes on the 7th day in order to reach her goal.
Answer:
26 minutesStep-by-step explanation:
Let; x be the minutes exercised on the seventh day .30 + 40 + 37 + 42 + 45 + 50 + x ÷ 6 = 45244 + x ÷ 6 = 45Now; the least common multiple is 6 So; multiplying 6 with both sides.6 * 244 + x ÷ 6 = 45 *6244 + x = 270Making x the subjectx = 270 - 244x = 26Therefore Sina must exercise for 26 minutes on the seventh day in order to reach her goal exactly.Note:Mean is given by adding of numbers given divided by the number of numbers .Example.Find the mean of 2,4,3so;we have 3 numbersadding numbers = 2 + 4 + 3÷3 = 9÷3 = 3 therefore the mean is 3 .So; with your question the mean is already given but left with one digit which is the 26 .Hence,you have to represent it by a variable and equate it to the mean given.with change of subject and further calculation , you will get the result which is the 26 minutesPLSSSSSSSSSSSSSSSSs Help me i have to send this to my math teacher before yk back to school starts

How do you know which direction to move on a number line when adding integers?
Step-by-step explanation:
To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.

Find the value of x
What’s the missing angle?
Answer:
x = 15, 72 degrees
Step-by-step explanation:
4x + 12 + 108 = 180
4x + 120 = 180
4x (+ 120 - 120) = 180 - 120
4x = 60
4x/4 = 60/4
x = 15
4x + 12
4(15) + 12
60 + 12

B. 12x + 72; 10x + 3
C. 12x + 72; 3x + 10
D. 6x + 36; 3x + 10
Step-by-step explanation:
Perimeter = 12 + x + 6 + 2x + 5
Perimeter = 3x + 23.
Area = ½ × b × h
Area = ½ × 12 × (x + 6)
Area = 6(x + 6)
