Answer:

9 9/20

Step-by-step explanation:

4 1/5 * 2 1/4

Change the mixed nubers to improper fractions

4 1/5 = (5*4+1)/5 = 21/5

2 1/4 = (4*2+1) /4 = 9/4

21/5 * 9/4 = 189/20

Now we change it back to a mixed number

20 goes into 189   9 times   (20*9 = 180  with 9 left over)

9 9/20

X –12 = -8x + 6 a.x = 2 b.x = -2 c.x = 3 d.x = -3
Naddik [55]

Answer:

<u>(a) x = 2</u>

Step-by-step explanation:

x - 12 = -8x + 6

First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)

x - 12 + 8x = 6

x + 8x = 6 + 12

9x = 18

Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)

x = \frac{18}{9}

x = 2

Therefore, your answer is (a), since x = 2.

<em>I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!</em>
