Answer:

x = 9

Step-by-step explanation:

Step 1: Solve both sides by distributing the values.

3x+9-2x+2 = 5x-25

Step 2: Put the like terms together.

3x-2x-5x = -25-9-2

-4x = -36

Step 3: Divide both sides by -4 to get the value of x.

\frac{-4x}{-4} = \frac{-36}{-4}

x = 9

Let's verify the answer.

3x+9-2x+2 = 5x-25

3(9)+9-2(9)+2 = 5(9)-25

27+9-18+2=45-25

20 = 20

Answer:

x=9

Step-by-step explanation:

Distribute:

3x+9-2x+2=5x-25

Combine like terms:

x+11=5x-25

Solve:

x-x+11=5x-x-25

11=4x-25

11+25=4x-25+25

36=4x

Divide by 9:

x=9.

Hope this helps :D

dangina [55]

Answer:

b. x= -6 or x=2

Step-by-step explanation:

|2x+ 4| = 8

The absolute value equation has 2 solutions, one positive and one negative

2x+4 = 8           2x+4 = -8

Subtract 4 from each side

2x+4-4 = 8-4      2x+4-4 = -8-4

2x = 4                  2x = -12

2x/2 =4/2              2x/2 = -12/2

x =2                      x = -6

MAVERICK [17]

Answer:

B & C

Step-by-step explanation:

Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.

A-(5)(0.6)*7=21

B-(4/5)(15)+8=(0.8)(15)+8=20

C-4(8+2)/2=4(10)/2=40/2=20

D-14+4(2+3)=14+4(5)=14+20=34

If you need any clarification just lmk :)

3x+2=x+4(x+2) how do you do it step by step?
Katena32 [7]
Distribute 4 with x and 2 to get the equation 3x+2=x+4x+8. Combine x and 4x to get 5x. Minus 3x from each side. Now you should have 2=2x+8. Subtract 8 from both side to get -6=2x. Divide and you get x=-3

10 cans of mushrooms cost $27.80. The cost of each can is the same. What is the cost of
skelet666 [1.2K]

Answer:

This problem gives us the total amount of cans and it also gives us the total cost and asks us to find the cost of each can when every can costs the same amount.  To do this we need to $ to be on the top and the can on the bottom because we say price PER can.

\frac{total\ price}{total\ amount\ of\ cans}

\frac{\$27.80}{10\ cans}

\$2.78\ per\ can

Therefore, our final answer is that each can costs $2.78
