What does x equal 3/4(x+9)=15

To solve this problem, we will use the distributive property.
3/4(x + 9) = 15
3/4x + 6.75 = 15
Now we will subtract 6.75 from both sides of the equation.
3/4x = 8.25
To get rid of the fraction, we will multiply 8.25 by 4, then divide it by 3.
3/4x • 4 ÷ 3 = 8.25 • 4 ÷ 3
x = 11
Another way to do this would be to divide 3 by 4 and write .75x, then divide .75 into 8.25.  It would still get us 11.
In this equation, x is equal to 11.

Yuki bought a pound of confetti for \$12$12. What is the price, in dollars, per ounce of confetti? There are 1616 ounces in 11 p
tatiyna

Answer:

$0.75

Step-by-step explanation:

We have been given that Yuki bought a pound of confetti for $12.

To find the price of per ounce of confetti, we will divide the total price of 1 pound confetti by number of ounces in 1 pound.

1 pound = 16 ounces.    

Let us divide 12 by 16 to find the price of confetti per ounce.

\text{Price of per ounce confetti}=\frac{12}{16}

\text{Price of per ounce confetti}=\frac{3}{4}

\text{Price of per ounce confetti}=0.75

Therefore, the price of per ounce confetti is $0.75.

Solve the system by substitution.<br> x + 6y = -2<br> -x= 3y - 10
TiliK225 [7]

Answer:

x = 22, y = -4

Step-by-step explanation:

x + 6y = -2 --- Equation 1

-x = 3y - 10 --- Equation 2

Equation 2 ×(-1): x = -3y + 10 --- Equation 3

Substitute x = -3y + 10 into Equation 1:

x + 6y = -2

-3y + 10 + 6y = -2

3y + 10 = -2

3y = -2-10

    = -12

y = -12 ÷ 3

y = -4

Substitute y = -4 into Equation 3:

x = -3y + 10

x = -3(-4) + 10

  = 12 + 10

x = 22
