16 48 Sonny substituted 5 for x in the proportion - 15 and cross multiplied to get 240 - 240. Why is this?
because the cross sums of the proportion are equal
o because the cross differences of the proportion are equal
because the cross products of the proportion are equal
because the cross quotients of the proportion are equal

Because of the cross quitients of the protion are equal

Step-by-step explanation:

It’s C because you have to cross m u l t i p l y  to get the correct )

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
