Answer:
Step 1: Simplify both sides of the equation.
−7+3(8n−8)=8(7+3n)
−7+(3)(8n)+(3)(−8)=(8)(7)+(8)(3n)(Distribute)
−7+24n+−24=56+24n
(24n)+(−7+−24)=24n+56(Combine Like Terms)
24n+−31=24n+56
24n−31=24n+56
Step 2: Subtract 24n from both sides.
24n−31−24n=24n+56−24n
−31=56
Step 3: Add 31 to both sides.
−31+31=56+31
0=87

Answer:
x. a.
y. b
z. c.
Step-by-step explanation:
So from the middle column, we know that each row or colum must be -12 because 1 - 8 - 5. x + 1 - 12 should be = - 12, so x -11 = 12, so x = -1
For z, - 12 + 3 + z = -12, so z = -3
For y, y - 5 + z = -12, but we know z so we can plug in -3:
y - 5 - 3 = - 12
y - 8 = -12
so y must be -4
Barry made the model to show multiplying a fraction by a fraction. Which multiplication sentence does the model show? A grid with 3 rows of 6 columns showing 18 squares total. The 12 squares in the top two rows are shaded yellow, the 15 squares in the first 5 columns are shaded blue. The shading overaps to make green in 10 squares. 13×23=29 26×56=518 13×26=19 23×56=59
Given:
Number of rows = 3
Number of columns = 6
Number of square boxes = 18
yellow square boxes in the top two rows = 12
Blue square boxes in the first 5 columns = 15
Number of green boxes (shading overlaps) = 10
To find:
The model to show multiplying a fraction by a fraction.
Solution:
2 rows out of 3 are shaded yellow.
Fraction for yellow = [tex]\dfrac{2}{3}[/tex]
5 columns out of 6 are shaded blue.
Faction for blue = [tex]\dfrac{5}{6}[/tex]
10 out of 18 squares are green.
Faction for green = [tex]\dfrac{10}{18}=\dfrac{5}{9}[/tex]
Now,
[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{10}{18}[/tex]
[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{5}{9}[/tex]
Therefore, the correct option is D.
The correct option is D.
The calculation is as follows:
2 rows out of 3 are shaded yellow.
Fraction should be [tex]2\div 3[/tex]
Now
5 columns out of 6 are shaded blue.
Fraction should be [tex]5 \div 6[/tex]
And,
10 out of 18 squares are green.
Fraction should be [tex]10 \div 18 = 5\div 9[/tex]
Now
[tex]\frac{2}{3} \times \frac{5}{6} = \frac{10}{18}\\\\ \frac{2}{3} \times \frac{5}{6} = \frac{5}{9}[/tex]

5/8x + 1/5x =66 what does X equal?
Answer:
x = 80
Step-by-step explanation:
Find a common denominator for 5/8x and 1/5x
25/40x + 8/40x = 66
Add 25/40x and 8/40x together.
33/40x
33/40x = 66
Divide both sides by 33/40
x = 80

Brianna ran 6 laps around a circular track with the diameter of 120 feet how far did she run
Answer:
2261.94671
Step-by-step explanation:
You must first find the circumference of the track. Using 2(pi)r.
Where pi=3.14... and r=radius
you can find the radius by dividing the diameter by 2, 120/2=60
Afterwards you input 60 into the equation. 60*(pi)*2= 376.99111843077515
Using that number you multiply it by 6 because she ran the circumference 6 times. 6*376.99111843077515 = 2261.94671
NOTE: The question may require you to simplify at certain times so answers may vary slightly. EX: pi = 3.14, Circumference = 377
The price of fancy coffee has increased 9% each year for the last several years.
If the current cost $8 per pound, what did a pound cost two years ago
Answer:
$6.56
Step-by-step explanation:
First, take 8 and divide it by 100. Then you have 0.08. multiply that by 9. You get 0.72, that is how much the price increases every year. multiply that by 2, and you get 1.44. subtract 1.44 from 8, and you are left with $6.56, the price it was two years ago.

Answer:
(-162)/7 or -23 1/7 as a mixed fraction
Step-by-step explanation:
Simplify the following:
(-36)/14 (-18) (-3)/6
Hint: | Express (-36)/14 (-18) (-3)/6 as a single fraction.
(-36)/14 (-18) (-3)/6 = (-36 (-18) (-3))/(14×6):
(-36 (-18) (-3))/(14×6)
Hint: | In (-36 (-18) (-3))/(14×6), divide -18 in the numerator by 6 in the denominator.
(-18)/6 = (6 (-3))/6 = -3:
(-36-3 (-3))/14
Hint: | In (-36 (-3) (-3))/14, the numbers -36 in the numerator and 14 in the denominator have gcd greater than one.
The gcd of -36 and 14 is 2, so (-36 (-3) (-3))/14 = ((2 (-18)) (-3) (-3))/(2×7) = 2/2×(-18 (-3) (-3))/7 = (-18 (-3) (-3))/7:
(-18 (-3) (-3))/7
Hint: | Multiply -18 and -3 together.
-18 (-3) = 54:
(54 (-3))/7
Hint: | Multiply 54 and -3 together.
54 (-3) = -162:

Raju’s father’s age is 5 years more than three times Raju’s age. Find Raju’s age,
if his father is 44 years old. ( 13 years)
please help
Answer:
Step-by-step explanation:
In order to find the answer, let's work backwards to find the original. We have to do the opposite to get to the Raju's age. We will start with his fathers age. (44) Then we will subtract five from it so that it will be divisible by three.
44 - 5 = 39
Then we just have to divide by 3.
44/3 = 13
His age is 13 years old.

The distance to the moon is 238,900 miles. How is this expressed in scientific notation?
a. .00238 X 10^5
b. 2.389 x 10^5
c. 2.3 X 105
d. 2.389 x 10-5
Answer:
Answer is b because scientific notation is a variable between 0-10 to the power of a number depending on how many digits it has.
A number from 1-10 in 238,900 miles is 2.389 so the base variable is 2.389. The decimal got moved from 238900. to the left. It moved 5 places.
It went like this;
1 left: 23890.0
2 left: 2389.00
3 left: 238.900
4 left: 23.8900
5 to the left: 2.38900
So the scientific notation is 2.389^5
