Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. clear check how many pounds of gravel does it take to cover one sq

timama [110]

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.

What is the value of x? Enter your answer in the box. x =

galina1969 [7]

The answer is: " 11 " .
____________________________________________________
→ " x = 11 " .
____________________________________________________
Explanation:
____________________________________________________
Set up the ratio/ proportion as a fraction:

6 cm / 48 cm = 5 cm / (3x + 7) ;

→ The "cm" units cancel out; since: "cm/cm = 1 " ;

→ The "6/48" = "(6 ÷ 6) / (48 ÷ 6) = " 1/8 " ;

→ Rewrite as: $\frac{1}{8} = \frac{5}{3x + 7}$ ;

Now, we can "cross-multiply" :
__________________________________________________

Note: $Given: \frac{a}{b} = \frac{c}{d}$ ; $ad = bc$ ;
{b $\neq 0$ ; d $\neq 0$ } .
__________________________________________________

As such:

1 * (3x + 7) = 8 * 5 ;

→ 3x + 7 = 40 ;

Subtract "7" from each side of the equation:

→ 3x + 7 − 7 = 40 − 7 ;

to get:

→ 3x = 33 ;

Now, divide each side of the equation by "3" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 3x / 3 = 33 / 3 ;

to get:
____________________________________________________

→ " x = 11 " .
____________________________________________________
→ The answer is: " 11 " .
