20000 gallons of water are in pool

<em><u>Solution:</u></em>

Given that To maintain an acceptable level of chlorine in your pool you add 1.4 gallons of chlorine

This is 0.007℅ of the amount of water in your pool

To find: gallons of water are in your pool

From given question,

1.4 gallons of chlorine = 0.007℅ of the amount of water in your pool

Let "x" be the amount of water in your pool

Therefore,

1.4 = 0.007 % of x

1.4 = \frac{0.007}{100} \times x\\\\1.4 = 0.00007 \times x\\\\x = \frac{1.4}{0.00007}\\\\x = 20000

Thus 20000 gallons of water are in pool

Answer:  The two triangles are similar because the angles are congruent.

Step-by-step explanation: If you add the given measures of the angles given, then subtract from 180, the remainder is equal to the measure of the angle given for the other triangle.

180 - (103 + 22) = 55

180 - (22 + 55)  = 103

So both triangles have the same angle measurements.

Solve the system of equations : y = x/2 , y = -x - 3 . You can use any method you wish for solving systems of equations. Check y
lorasvet [3.4K]

Answer:

x=−2 and y=−1

Step-by-step explanation:

<u>Problem:</u>

Solve y=x2;y=−x−3

<u>Steps:</u>

I will solve your system by substitution.

y=1/2x;y=−x−3

Step: Solve y= 1/2x for y:

Step: Substitute 1/2 x for y in y=−x−3:

y=−x−3

1/2x= =−x−3

1/2x+x=−x−3+x(Add x to both sides)

3/2x = -3

3/2x/3/2 = -3/3/2 (Divide both sides by 3/2)

x=−2

Step: Substitute −2 for x in y=1/2x:

y=1/2x

y=1/2(-2)

y=−1(Simplify both sides of the equation)

<u>Answer:</u>

x=−2 and y=−1
