So the coefficient are the numbers when you multiply a number by a varriable

for example the first part of this equation starts with 3x

3 is the number and x is the viable

that means that the first coefficient in this problem is 3

so moving forward the second coeffifient would be 7 since 7y comes after the first coefficient

PLEASE HELP 100 POINTS GUARANTEED! PLEASE PUT THE ANSWER IN AN ALGEBRAIC EXPRESSION!!! ANSWER ALL AND YOU WILL RECEIVE BRAINLIES
zlopas [31]

Answer:

1.

-2 = x/4 + 1

Subtract 1 from both sides:

-2 - 1 = x/4 + 1 - 1

-3 = x/4

Multiply both sides by 4:

-3 * 4 = x/4 * 4

-12 = x

2.

3x+5

3.

X= 12 or 18

This could be read two different ways.

0=2/3x-12

12=2/3x

12÷2/3=x

12*3/2=x

18=x

—-OR—-

0=2/3(x-12)

0=2/3x-8

8=2/3x

8÷2/3=x

8*3/2=x

12=x

Bess [88]

Answer:

It will take 22.5 weeks for her to save up to buy the dress.

Step-by-step explanation:

1/3 of $6.00 is 2.

(6 ÷ 3 = 2)

So she's saving $2 each week.

Now we need to divide $45 by $2 to get the number of weeks.

45 ÷ 2 = 22.5
