4(5x-6)=2(8x+10) how to solve

Pavel [41]

Hello! :)

Answer:

$\boxed{X=11}$

*The answer must have a POSITIVE sign!*

Step-by-step explanation:

Expand with distributive property: a(b+c)=ab+ac

4*5=20

6*4=24

20x-24

2*8=16

2*10=20

16x+20

20x-24=16x+20

First, you add by 24 both sides of an equation.

20x-24+24=16x+20+24

20x=16x+44

You subtract by 16x both sides of an equation.

20x-16x=16x+44-16x

4x=44

Then, you divide by 4 both sides of an equation.

4x/4=44/4

Divide by the numbers from left to right.

44/4=11

X=11 is the final answer

Hope this helps!

Have a nice day! :)

Paula kitten weighs 3 1/2 pounds write this weight in the boxes using pounds and ounces.

Elenna [48]

Answer:

Step by step explanation

First, we have to convert 3 1/2 into a decimal, so we have to do the following:

1/2 = 1 divided by 2 3 1/2 = 3 + (1÷2) = 0.5 (1 ÷ 2 done by long division)

Then we add the whole number.

3 + 0.5 = 3.5

Next, we multiply

3.5 x 16 = 56 ounces.
