Answer:
x = 26.5
Step-by-step explanation:
Step 1: Write equation
(t + 10.5) + 2t + 90 = 180
Step 2: Solve for <em>t</em>
<u>Combine like terms:</u> 3t + 100.5 = 180
<u>Subtract 100.5 on both sides:</u> 3t = 79.5
<u>Divide both sides by 3:</u> t = 26.5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
<u>Substitute:</u> (26.5 + 10.5) + 2(26.5) + 90 = 180
<u>Parenthesis:</u> 37 + 56 + 90 = 180
<u>Add:</u> 180 = 180
∴ x = 26.5
Answer:
8
Step-by-step explanation:
First, simplify the expression given: 20 + 60 = 80
You are solving for the amount of "tens" the number has. Divide by 10: 80/10 = 8
8 is your answer.

Answer:
726
Step-by-step explanation:
The simple interest formula is as follows
AV=PV(1+it)
At time four this means that we have
AV=600(1+.042*5)
600*1.21= 726
1001/2=? $ 0.05(x)
1001/3=? $ 0.10(x)
1001/4=? +$ 0.25(x)
