Answer:
I'm pretty sure it's dark blue. It says below so that implies negative.
4.74/.06=79
19.44/.54=36
I used a calculator. You can change each decimal into a fraction to solve too.
Answer:
-3
Step-by-step explanation:
Step 1: Write equation
-7.6(x - 1) = 7.3 - 7.4x
Step 2: Solve for <em>x</em>
<u>Distribute -7.6:</u> -7.6x + 7.6 = 7.3 - 7.4x
<u>Add 7.6x on both sides:</u> 7.6 = 7.3 + 0.2x
<u>Subtract 7.3 on both sides:</u> 0.3 = 0.2x
<u>Divide both sides by 0.2:</u> x = 1.5
Step 3: Find <em>-2x</em>
-2(1.5) = -3
They are perpendicular to each other
