A restaurant manager needs to rope off a rectangular section for a private party. The length of the section must be 7.4 m. The manager can use no more than 23 m of rope. Which inequality could you use to find the possible widths of the roped off section

Answers

Answer 1

Answer:

Answer:

$14.8+2W\leq 23$

The value of the width must be less than or equal to 4.1 meters

Step-by-step explanation:

we know that

The perimeter of the rectangular section is given by

$P=2L+2W$

we have

$L=7.4\ m$

substitute

$P=2(7.4)+2W$

$P=14.8+2W$

Remember that

The manager can use no more than 23 m of rope

The perimeter must be less than or equal to 23 m

$14.8+2W\leq 23$

solve for W

subtract 14.8 both sides

$2W\leq 23-14.8$

$2W\leq 8.2$

divide by 2 both sides

$W\leq 4.1\ m$

The value of the width must be less than or equal to 4.1 meters

Which math expression represents the phrase?9 times the sum of a number and 7

A.

9 · n + 7

B.

9 · (n + 7)

C.

9 · (n – 7)

D.

9 · (n · 7)

Answers

"The sum of a number and 7"
Sum implies addition.
We would write this part as n + 7.

Then we would write the "9 times" part in like this:
9 · (n + 7)
We can't write just 9 · n + 7 without the parentheses, because then we would be multiplying just 9 and n instead of 9 and the sum of n and 7. (order of operations says we must do multiplication first)
