Step-by-step explanation:
If 3/5 of all the brownies is 21, then 5/3 of 21 is the number of the brownies that Lauren brought in.
That probably sounded super confusing. When multiplying a number by a reciprocal of a fraction (a fraction where the numerator and denominator is reversed), the previous fraction multiplication is reversed.
Multiplying 21 with 5/3 will give us the original number of brownies.
Lauren originally brought 35 brownies.
Y=1/2x-4
I think thats the answer

1.
B. 8........(8 + 7)(8 - 8) = 0
C. -7........(-7 + 7)(-7 - 8) = 0
2.
A. 1/3.......(3*1/3 - 1)(5*1/3 + 20) = 0
C. -4.......(3*-4 - 1)(5*-4 + 20) = 0
Hope this helps! :)
