The equation 2.2x − 4.4 = 1.8x can be transformed to form which of the following expressions?
a. 0.4x = 4.4
b.4.0x = 4.4
c.0.4x = −4.4
d.4.0x = −4.4

Move the 2.2x over to the other side by subtraction and you end up with

-4.4 = -,4x
which is the same as A when each side is multiplied by -1

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
