Convert 1/5 into a decimal. Which is .20 or 20% and 20+50=70 100-70= 30%

What is average of 39, 43, 28, 36, and 29?<br><br> A. 30<br> B. 35<br> C. 40<br> D. 175

elena-s [515]

To find the average, find the mean: add all the numbers together and divide by the number there is.

First add all the numbers together:
39 + 43 + 28 + 36 + 29 = 175

Next, divide 175 (the total) by 5 (because there are 5 numbers)

175/5 = 35

35 is your average.

hope this helps

What is 3/8x + 15/2=18

mart [117]

Let's solve for x --

Isn't it always a little easier to solve a math problem with starting by rewriting the equation?

3/8x + 15/2 = 8

Step 1) Subtract 15/2 from both sides

3/8x + 15/2 - 15/2 = 8 - 15/2

3/8x = 1/2

Step 2) Multiply both sides by 8/3

(8/3) × (3/8x) = (8/3) × (1/2)

x = 4/3

FINAL ANSWER -

x = 4/3

2. Delia and Beto left for school at the same time.

Tema [17]

<u>Answer:</u>

Beto will get to the school first.

<u>Step-by-step explanation:</u>

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes $\frac{3}{4} \times 16 =$ 12 minutes to reach school.

While Beto lives 3 1/2 miles from school and bikes at a pace of 3 minutes per mile.

So Beto takes $\frac{7}{2} \times 3 =$ 10.5 minutes to reach school.

Therefore, Beto will get to the school first.
