-2/3(3x-9) = 15 please help
Lina20 [59]
Your answer would be x=-10.5

First distribute -2/3 to 3x and -9
-2x+6=15
Then subtract 6 from both sides
-2x=9
Divide both sides by -2
x=-4.5

levacccp [35]

Answer:

4x+11 is the answer.

Step-by-step explanation:

( 4*2-x+3)-(3*2-5x-6)

=(8-x+3)-(6-5x-6)

=(11-x)-(0-5x)

=(11-x)-(-5x)

=11-x+5x

All tubes of watercolor paint at an art supply store have the the same price. An artist has a coupon for $0.50 off each tube of
BlackZzzverrR [31]

Let us assume the regular price of each tube of paint = r.

0.50 off each tube.

New price of each tube = r - 0.50.

She buy 6 tubes.

Total price of 6 tubes = 6×(r-0.50).

We are given total price = $84.30 .

Therefore, we can setup an equation

6×(r-0.50) = 84.30.

Distributing 6 over (r-0.50), we get

6r - 3.0 = 84.30

Adding 3.0 on both sides, we get

6r - 3.0+3.0 = 84.30+3.0

6r = 87.30

Dividing both sides by 6, we get

6r/6 = 87.30/6

r = 14.55

<h3>Therefore, required equation is 6(r-0.50) = 84.30 and the regular price of each tube of paint is $14.55.</h3>

5<br> 8<br> y<br> Find the exact value of y.<br> y =
inn [45]

Answer:

y=2\sqrt{10}

Step-by-step explanation:

By applying geometric mean theorem in the given right angle,

\frac{AD}{DB}=\frac{DB}{CD}

By substituting values in the given ratio,

\frac{5}{y}= \frac{y}{8}

y^2=8\times 5

y^2=40

y=2\sqrt{10}

Exact value of y is 2\sqrt{10}.
