Answer:

(D) 15m+2n

Step-by-step explanation:

The  equation is given by:

8m+4n+7m-2n

Let y= 15m+2n, then

Rewriting the like terms together and then adding or subtracting them, we have

y=8m+7m+4n-2n

y=15m+2n

Hence, simplified form of the given equation is 15m+2n.

Therefore, option D is correct.

2^3+5x(6+4)÷2, for MATH LIB
Lynna [10]

Evaluate 2^3+5x(6+4)÷2 following Order of Operations rules (PEMDAS):

Work within parentheses is done first, followed by exponentiation, and then mult. and div., and finally add'n. and subtr'n.

Thus, 2^3+5x(6+4)÷2 becomes 2^3+5x(10)÷2

8 + 50x/2

8 + 25x

A concert cleanup crew has 6 workers and one cleanup kit.
myrzilka [38]

Answer:

Option (D)

Step-by-step explanation:

At every 6 crew workers number of clean up kits required = 1

Therefore, for 1 crew worker number of kits required = \frac{1}{6}

And number of kits required for w workers = \frac{w}{6} = w ÷ 6

If w = 54

Number of kits required = \frac{54}{6}=9

If w = 60

Number of kits required = \frac{60}{6}=10

If w = 66

Number of kits required = \frac{66}{6}=11

Therefore, table given in Option (D) is the correct table.
