Move terms

12+1.5a=3a

Collect the like terms

1.5a3a=-12

Divide both sides by -1.5

-1.5a=-12

a=8

Isolate the a. Note the equal sign, what you do to one side, you do to the other.

First, subtract 1.5a from both sides

12 + 1.5a (-1.5a) = 3a (-1.5a)

12 = 3a - 1.5a

12 = 1.5a

Isolate the a. Divide 1.5 from both sides

(12)/1.5 = (1.5a)/1.5

a = 12/1.5

a = 8

8 is your answer for a.

______________________________________________________

Check: Plug in 8 for a.

12 + 1.5(8) = 3(8)

Simplify. Remember to follow PEMDAS.

12 + 1.5(8) = 24

12 + 12 = 24

24 = 24 (True)

EastWind [94]

Answer:

1) 4 bottles

2) $0.75

3) $5.25

Step-by-step explanation:

1)9/3 = 3 so you must divide 12 by 3

12/3=<u>4 bottles</u>

2)12/1=12

divide 9 by 12

9/12 =<u>$0.75</u>

3)12/7 =\frac{12}{7} (The actually number is too long to write so just leave it in fraction form)

9÷12/7=<u>$5.25</u>

Solve for the product of 1,325 x 10₁ = ________. Then, explain how you moved the decimal to get the product.
professor190 [17]

Answer:

13,250.0

When we multiply a number with 10, the decimal place of the original number will move to the right by one step.

Step-by-step explanation:

We can write the number 1,325 as 1325.00

Now, we have to solve the product of 1,325 \times 10^{1}

So, 1,325 \times 10^{1}

= 1,325.00 \times 10^{1}

= 13,250.0 (Answer)

Therefore, when we multiply a number with 10, the decimal place of the original number will move to the right by one step and when we divide a number with 10, then the decimal place of the original number will move by one step to the left. (Answer)
