Which algebraic expression has a term with a coefficient of 3?

Mathematics
1 answer:
Musya8 [376]3 years ago

A. Is the answer because a coefficient is the number that is attached to a variable or in front of it. There cannot be a parenthesis in between them like in letter D. So your answer is letter A because the 3 in 3y+1 is a coefficient. Hope this helps!

How to find rate of change on a table
LekaFEV [45]

Answer:

   __X__l__Y_

        1     l    3

        5    l    6

        9     l    9

        13   l    12

        17   l    15

        21   l    18

On the right side, the numbers get larger by adding three each time. On the left side, the numbers get larger by adding 4 each time. It would be the same for any other pair of numbers when you add 4 to the left, and 3 to the right. For instance, the next pair would be (25 , 21). 25 would be the X value, and 21 would be the Y value.

-12 + 6x = 6 + 5(x - 2) <br><br> Please help and EXPLAIN
icang [17]

Answer: x=8

Step-by-step explanation:

Distribute 5(x) and 5(-2)

-12 + 6x = 6 + 5x + (-10) OR 5x - 10

Flip if you'd like

6x - 12 = 6 + 5x - 10

Combine like terms

6x−12=(5x)+(6+−10)

6x - 12 = 5x - 4

Subtract 5x from both 6 and 5

6x - 5x = 5x - 5x

5x cancels out, so you're left with x, 12, and -4

x - 12 = -4

Add 12 to 12 and -4

12 + 12 = -4 + 12

12 cancels out

-4 + 12 = 8

x = 8
