Answer:
4 inches
Step-by-step explanation:
We can set up a proportion to find out the length value (assuming x is the length of the frame)
We multiply 12 and 3...
And divide by 9...
So, the length of the frame is 4 inches.
Hope this helped!
<h2><u>EQUATION</u></h2><h3>Exercise: -30 = 5(x + 1)</h3>
First, apply the distributive property:
-30 = 5(x + 1)
-30 = 5x + 5
Substract 5 from both sides:
-30 - 5 = 5x + 5 - 5
-35 = 5x
Divide both sides by 5:
Let's check the answer:
-30 = 5(x + 1)
-30 = 5(-7 + 1)
-30 = 5(-6)
-30 = -30
The answer is correct.
<h3><u>Answer</u>. The value of x = -7.</h3>
