Morgarella [4.7K]

Answer:

10

Step-by-step explanation:

"three times r" = 3r

"three times r minus ten" = 3r - 10

"product of 5 and the difference of three times r minus ten"

= 5 (3r - 10)

given that r = 4,

the expression becomes

5 (3r - 10)

= 5 [3(4) - 10]

= 5 [12 - 10]

= 5 (2)

= 10

If you know the rate of a water leak in gallons per hour, how can you find the number of hours it takes for 1 gallon to leak out

Evgen [1.6K]

1/the rate of leakage per hour

This will give you the time it takes for 1 gallon to leak out in hours.

For example, if something is leaking at the rate of 12 gallons per hour, it will take 1/12 of an hour for 1 gallon to leak out. ( or 5 min)

The length of a picture frame is 2 inches more than the width. The perimeter of the frame is 36 inches. What is the length of th

sveta [45]

Let the width be $x$
∴the length = $x+2$
perimeter=2(l+b)
36= $2(x+2+x)$
36= $2(2x+2)
=4x+4$
$4x=32 x=8$
∴∴the length = $x+2 = 8+2
 =10$
