Answer:
36
Step-by-step explanation:
10-3=7+2=9
4×9=36
36 is the answer
0 it has no simplest form
Answer:
m ≤ 60 (look at the picture)
Step-by-step explanation:
<em>5 greater than m is no more than 65</em>
m + 5 ≤ 65 <em>subtract 5 from both sides</em>
m + 5 - 5 ≤ 65 - 5
m ≤ 60
7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
From given question,
252 lb = 36 ft² ..........(1)
The number of pound for an area of 1 square foot is calculated as follows:
x = 1 ft² .......(2)
The area and the amount of gravel are illustrations of proportions.
From (1) and (2) we get an equation,
⇒ x × 36 = 252 × 1
⇒ x = 252/36
⇒ x = 7 lb
We need to find the area that could be covered with 315 lb of gravel
The area to be covered with 315 lb gravel is calculated as follows:
315 lb = y ............(3)
From (1) and (3) we get an equation,
⇒ y × 252 = 36 × 315
⇒ y = 45 ft²
Therefore, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
