Lets solve your equation.

30 = -5/4y

step 1: Flip Equation

-5/4y =30

Step 2: Multiply both sides by 4/(-5)
(4/-5)*(-5/4y) = (4/-5)*30

y = - 24

Answer: y = - 24

there you go.

Hi there!

In order to solve for y, we need to divide each side by -5/4.

30 ÷ -5/4
= 30 × -4/5
= -120/5
= -24

y = -24

Hope this helps!

he weight of a chimpanzee, y, in pounds, x months after birth is modeled by the equation y=1.5x+8. Which represents the equation

soldi70 [24.7K]

The equation that represents x when solved is $x=\frac{y-8}{1.5}$

Given the equation that expresses the weight of a chimpanzee with respect to the months of birth as:

y = 1.5x + 8

We are to express x in terms of "y"

$y = 1.5x + 8$

Subtract 8 from both sides

$y -8= 1.5x + 8-8\\y-8 = 1.5x\\Swap\\1.5x = y - 8$

Divide both sides by 1.5

$\frac{1.x}{1.5}= \frac{y-8}{1.5} \\x=\frac{y-8}{1.5} \\$

Hence the equation that represents x when solved is $x=\frac{y-8}{1.5}$

At a certain real estate firm, realtors selling homes receive a commission of: 7% for the first $100,000 of the selling price, a

scoray [572]

Answer: The actual price of house sold at $109000.

Step-by-step explanation:

Since we have given that

Selling price = $100000

Rate of commission = 7%

So, Amount of commission would be

$\dfrac{7}{100}\times 100000\\\\\=\$7000$

Total commission = $7540

So, Remaining amount of commission would be

$\$7540-\$7000\\\\=\$540$

Rate of commission exceeding $100000 = 6%

Let the selling price of house be 'x'.

According to question,

$\dfrac{6}{100}\times x=540\\\\0.06x=540\\\\x=\dfrac{540}{0.06}\\\\x=\$9000$

Hence, the actual price of house sold at

$100000+$9000=$109000.

Uncle percy sold t-shirts at the show. Now he only have 10% of the t-shirts he started with. If he has 25 t-shirts now, how many

Nikitich [7]

Percy used to have 100% of the shirts (before he started selling them). Since then, he has given away 90% of the shirts and is now left with only 10% of what he used to have. He currently has 25 shirts, meaning that 25 is 10% of what he had.

Lets set up a proportion:

25 shirts : 10%
x shirts : 100%

x = 25*100 / 10
x = 2500 / 10
x = 250 shirts
Percy started off with 250 shirts.
