The equation 2.2x − 4.4 = 1.8x can be transformed to form which of the following expressions?

0.4x = 4.4
4.0x = 4.4
0.4x = −4.4
4.0x = −4.4

A) 0.4x = 4.4

Step-by-step explanation:

2.2x - 4.4 = 1.8x

We have to isolate the variable terms and constants

Step 1:  Add 4.4 on both sides, we get

2.2x - 4.4 + 4,.4 = 1.8x + 4,.4

2.2x = 1.8x + 4.4

Step 2: Subtract 1.8x from both sides, we get

2.2x -1.8x = 1.8x -1.8x + 4.4

0.4z = 4.4

Therefore, the answer is A) 0.4x = 4.4

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
