Answer:

a. y=\frac{2x}{x-5}

b. y=\frac{2-4x}{x-3}

Step-by-step explanation:

change switch x and y and then solve for y.

a. x=\frac{5y}{y-2}

x(y-2)=5y

xy-2x=5y

xy-5y=2x

y(x-5)=2x

y=\frac{2x}{x-5}

same for b.

b. x=\frac{3y+2}{y+4}

x(y+4)=3y+2

xy+4x=3y+2

xy-3y=2-4x

y(x-3)=2-4x

y=\frac{2-4x}{x-3}

3. Diego needs to grow 3.62 inches

Step-by-step explanation:

Work through numbers one and two like basic addition and subtraction.

Number three is a little more tricky becuase is is a word problem. Since Diego needs to be 39.37 inches tall, but he's only 35.75 inches tall, you can do this.

39.37

-35.75

-----------= 3.62 inches.

A handy way to think of addition and subtraction with decimals, is to take the decimals out, do the problem that way, and add the decimals right back in after you have worked the problem.

If you need help learning more about addition and subtracting with decimals, dont be afraid to ask your parents and your teachers.

out of 45 times at bat, Raul got 19 hits. Find Rauls batting average as a decimal rounded to the nearest thousandth.
Eduardwww [97]
<span>Raul only hit 19 times out of 45 bats.
Now, let’s find the average decimal value of Raul’s hit.
=> 19 hits
=> 45 bats
x = value in decimals

=> 19 = x * 45
=> 19 = 45x
Now, divide both sides with 45
=> 19/45 = 45x / 45
=> 0.4222222 = x
x = 0.422222……..
Since it is a repeating decimals, and we only need to find the thousandths value. Let’s get the value of Thousandths.
=> 4 = tenths
=> 2 = hundredths
=> 2 thousandths
Therefore the value of 19 hits out of 45 bats in decimals is
=> .422 </span>
