3(a - 1) + 2a = a + 1

Mathematics
1 answer:
tresset_1 [31]3 years ago
7 0

Answer:

a = 1

Step-by-step explanation:

Step 1: Write equation

3(a - 1) + 2a = a + 1

Step 2: Solve for <em>a</em>

<u>Distribute 3:</u> 3a - 3 + 2a = a + 1

<u>Combine like terms:</u> 5a - 3 = a + 1

<u>Subtract a on both sides:</u> 4a - 3 = 1

<u>Add 3 on both sides:</u> 4a = 4

<u>Divide both sides by 4:</u> a = 1

Lynna [10]
Basically, every zero a number has to the end, the higher the scientific notation will be. Because 1000 has three zeroes, 10^5 will go to 10^8. So, you will travel 7.5 x 10^8 miles.
