Answer:
One solution.
Step-by-step explanation:
Step 1: Write equation
5(x + 2) - 3 = 3x - 8x + 7
Step 2: Solve for <em>x</em>
<u>Distribute 5:</u> 5x + 10 - 3 = 3x - 8x + 7
<u>Combine like terms:</u> 5x + 7 = -5x + 7
<u>Add 5x to both sides:</u> 10x + 7 = 7
<u>Subtract 7 on both sides:</u> 10x = 0
<u>Divide both sides by 10:</u> x = 0
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
5(0 + 2) - 3 = 3(0) - 8(0) + 7
5(2) - 3 = 7
10 - 3 = 7
7 = 7
Answer:
You would need to score a 93% to have an average of 90.
Step-by-step explanation:
Well, to check my work you would need to find the average.
So, 93 + 92 + 88 + 87 = 360. Then you divide by four; 360 / 4 = 90. ^^
Answer:
<em>$600.00</em>
Step-by-step explanation:
To find the answer we must first <em>divide 3 by 100 to find its actual worth</em>, <em>3 ÷ 100 = 0.03</em>. Take <em>0.03 and multiply it by 5,000</em>, and you get<em> 150</em>. Now we have the <em>annual interest in a year</em>, so lets <em>multiply it by 4 years</em>, and we get <u><em>$600. </em></u>
