five \ eighths \to \frac{5}{8} \\\\ eleven \ twelves \to \frac{11}{12} \\\\ \frac{5}{8}^{(3}+\frac{11}{12}^{(2}= \\\\ =\frac{15}{24}+\frac{22}{24}= \\\\ =\boxed{\boxed{\frac{37}{24}}}

5/8 + 11/12
make the denominator the same
48 divided by 12 = 4
48 divided by 8 = 6
5 x 6 = 30
11 x 4 = 44
30/48 + 44/48
30 + 44 = 74
74 - 48 = 26
So the answer is 1 and 26/48 in its proper form.
Simplified, it would be 1 and 13/24. Mixed = 37/24 since you'll be adding 24.

Marks family traveled 7/10 of the distance to his grandmothers house on Saturday. They traveled 2/3 of the remaining distance on
worty [1.4K]

Answer: 1/5 of the total distance to his grandmothers house was traveled on Sunday

Step-by-step explanation:

The total distance to to his grandmothers house is assumed to be 1

Marks family traveled 7/10 of the distance to his grandmothers house on Saturday. The remaining distance would

1 - 7/10 = 3 /10

They traveled 2/3 of the remaining distance on Sunday. This means that the distance that they travelled on Sunday is

2/3 × 3/10 = 2/10 = 1/5

A certain right triangle with integer side lengths has perimeter $72$. What is its area?
JulijaS [17]

Answer: 216 square units

====================================================

Explanation:

A common pythagorean triple you may be familiar with is the 3-4-5 right triangle. This has two legs of 3 and 4, and a hypotenuse of 5. The perimeter is 3+4+5 = 7+5 = 12. Note how this is a factor of 72.

If we multiply the perimeter (12) by 6, then 12*6 = 72. So we have scaled the triangle by a factor of 6. Each length is 6 times longer

the side length 3 becomes 3*6 = 18

the side length 4 becomes 4*6 = 24

the side length 5 becomes 5*6 = 30

The new perimeter is 18+24+30 = 42+30 = 72

The last step is to find the area. The two legs of this triangle are the base and height

area = 0.5*base*height

area = 0.5*18*24

area = 9*24

area = 216

-----

Or you could find the area of the 3-4-5 right triangle to get

area = 0.5*base*height = 0.5*3*4 = 6

then multiply by 36 to get 6*36 = 216. The 36 is the square of the scale factor 6 we applied above. The new lengths are 6 times longer, so the new area is 6^2 = 36 times larger.

How do you solve <br>2v+18=16-4(v+7)
Andreyy89
2v + 18 = 16 - 4(v + 7)

Simplify by removing the parenthesis.

2v + 18 = 16 - 4v - 28

Now, simply add 4v to both sides.

2v + 4v + 18 = 16 - 28

Simplify.

6v + 18 = -12

Now, subtract 18 from both sides.

6v = -12 - 18

Simplify.

6v = -30

Finally, divide both sides by 6.

6v ÷ 6 = 30 ÷ 6

Simplify.

v = 5

~Hope I helped!~
