If 21 is added to a number the result is 40 less than twice the number what is the number?

1 answer:

7 0

If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)

x + 21 = 2x - 40 Add 40 to both sides
x + 61 = 2x Subtract x from both sides
61 = x Switch the sides to make it easier to read
x = 61

Zolol [24]

Answer:

The total cost of resurface the path is $\$600$

Step-by-step explanation:

step 1

Find the area of the path

The area of the path is equal to the area of the path plus the swimming pool minus the area of the swimming pool

$A=(14+3+3)(30+3+3)-(14)(30)$

$A=(20)(36)-(14)(30)$

$A=300\ ft^{2}$

step 2

Find the cost of resurface the path

Multiply the area of the path by $2 per square foot

$300*2=\$600$
