Question

Evaluate: 39/y + 5y if x = 3 and y = 5.

Answer 1

32.8

Explanation:

We are given the expression:

39/y +5y

We know that y is equal to 5. Therefore, we can substitute 5 in for every y.

39/5 + 5(5)

Solve from left to right according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, divide 39 by 5.

7.8+5(5)

Next, multiply 5 and 5

7.8+25

Finally, add 7.8 and 25

32.8

Answer 2

`answer = 32.8 \\ solution \\ (39)/(y) + 5y \\ = (39)/(5) + 5 * 5 \\ = (39)/(5) + 25 \\ = (39 + 25 * 5)/(5) \\ = (39 + 125)/(5) \\ = (164)/(5) \\ = 32.8 \\ hope \: it \: helps`
