Answer:

Well, y = 2x - 3.

Step 1:

Subtract 2x from both sides.

-y = -2x + 3.

Step 2:

Divide it all by negative 1.

y = 2x - 3.

IF YOU WANT TO SOLVE FOR X:

Well, x = .5y + 3/2

Which equals to:

(y + 3)/2.

Step 1:

Add y to both sides.

2x = y + 3.

Step 2:

Divide it all by 2:

x = .5y + 3/2

Which equals to:

(y + 3)/2.

They are the same.

A 72,000 gallon water tower is being drained. Two thousand gallons are drained in the first hour. How many hours will it take to

ololo11 [35]

Answer:

To drain the water tower it will take 36 hours.

Step-by-step explanation:

Given:

A 72,000 water tower is being drained, and in an hour 2000 gallons are drained.

Now, to calculate the hours it would take to drain total 72,000 gallons of water, we should divide the gallons of water drained in one hour by total gallons of water in the tower.

Gallons of total water in the tower ÷ Gallons of water drained per hour

$72000\div 2000$

$=\ 36$

Therefore, to drain the water tower it will take 36 hours.

3. True

Step-by-step explanation:

Remark

The point of this question is to encourage you to make use of your calculator. Every calculator can find square roots as far as I know.

Givens

$\sqrt{70}$ = 8.367

$\sqrt{72}$ = 8.49

$\sqrt{77}$ = 8.77

One

Point A is roughly 8.15. The square root of 70 is over 8.3 So square root 70 is to the right of point A. False.

Two

Square root 72 is 8.49. B is 8.3 and C is 8.6. The statement is True

Three

sqrt(77) = 8.77. Point D is 8.75. The answer is true, but I wouldn't want to bet money on it. The difference is slightly less than 2 100s.
