Move all terms containing x to the left, all other terms to the right. Add '-9.3' to each side of the equation. 9.3 + -9.3 + 8.9x = 0 + -9.3 Combine like terms: 9.3 + -9.3 = 0.0 0.0 + 8.9x = 0 + -9.3 8.9x = 0 + -9.3 Combine like terms: 0 + -9.3 = -9.3 8.9x = -9.3 Divide each side by '8.9'. x = -1.04494382 Simplifying x = -1.04494382</span>

I believe that the answer would be 26. First, put 26 for x and subtract 8.9 from 26 s 26 - 8.9 = 17.1. Next, you will subtract -4.5 from 17.1 which equals 12.6. So 26 is your answer.

Kimane and a friend picked apples. Kimane picked 4 2/3 and his friend picked 5 5/6 pounds. About how many pound of apples do the

Gala2k [10]

Answer:

$9\dfrac{1}{2}$

Step-by-step explanation:

To find many more pounds of apples Kimane and his friend needs to get, we first need to find out how many pounds of apples they picked together.

Kimane = $4\dfrac{2}{3}$

Friend = $5\dfrac{5}{6}$

We add them together to find out how many pounds of apples they currently have.

Total Pounds = $4\dfrac{2}{3}+5\dfrac{5}{6}$

Just to make the equation clearer, we separate the whole numbers from the fractions.

$=4+5+\dfrac{2}{3}+\dfrac{5}{6}$

$=9+\dfrac{2}{3}+\dfrac{5}{6}$

Now since we cannot add the 2 fractions directly since they have different denominators, we need to convert the $/dfrac{2}{3}$ into a fraction with the same denominator.

We multiply both the numerator and denominator by 2 to have the same denominator.

$\dfrac{2*2}{3*2}=\dfrac{4}{6}$

So now we have:

$=9+\dfrac{4}{6}+\dfrac{5}{6}$

$=9+\dfrac{9}{6}or1\dfrac{1}{2}$

$Total Pounds = 10\dfrac{1}{2}$

Now that we know how many pounds Kimane and his friend collected, we simply subtract 20 and the total amount Kimane and his friend had already collected.

$20-10\dfrac{1}{2}$
