Answer:
24 feet
Step-by-step explanation:
Use the area formula, A = lw, where l is length and w is width
Plug in the area and length of the classroom, then solve for w:
A = lw
672 = 28(w)
Divide each side by 28 to find w:
24 = w
So, the width is 24 feet.
Answer:
well that nice. How did it go?
Step-by-step explanation:
C.
because a, b, and d aren't porportional
but c x is divided by 2
Answer:
x = 14.5
Step-by-step explanation:
<u>Step 1: Subtract 5x from both sides
</u>
7x − 12 - 5x = 5x + 17 - 5x
2x - 12 = 17
<u>Step 2: Add 12 to both sides
</u>
2x - 12 + 12 = 17 + 12
2x = 29
<u>Step 3: Divide both sides by 2
</u>
2x / 2 = 29 / 2
<em>x = 14.5
</em>
Answer: x = 14.5
