Darya [45]

Answer:

(1 $\frac{1}{3}$ , 2 $\frac{1}{3}$ )

Step-by-step explanation:

Given the 2 equations

7x - y = 7 → (1)

x + 2y = 6 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the y- term

14x - 2y = 14 → (3)

Add (2) and (3) term by term to eliminate y

15x = 20 ( divide both sides by 15 )

x = $\frac{20}{15}$ = $\frac{4}{3}$ = 1 $\frac{1}{3}$

Substitute this value of x into either of the 2 equations and solve for y

Substituting in (2)

$\frac{4}{3}$ + 2y = 6

2y = 6 - $\frac{4}{3}$ = $\frac{14}{3}$ ( divide both sides by 2 )

y = $\frac{7}{3}$ = 2 $\frac{1}{3}$

The circumference of a round swimming pool at a resort is 157 feet. The pool is 6 feet deep but can only be filled to three-four

denis23 [38]

706.5 cubic feet of water should be put in the pool.

Step-by-step explanation:

Given,

The circumference of swimming pool = 157 feet.

The depth of the pool = 6 feet.

For safety purpose $\frac{3}{4}$ th of its height water is there.

To find the amount of the water should be there.

Formula

The volume of the pool = circumference×height

Now,

The height(h) of the water is = 6× $\frac{3}{4}$ ft = $\frac{9}{2}$ ft

So, the volume of the pool = 157× $\frac{9}{2}$ cubic feet

= $\frac{1413}{2}$ cubic feet = 706.5 cubic feet.

Hence,

706.5 cubic feet of water should be put in the pool.
