Solve for w in the proportion 32/40 = 28/w W= ?

32    =   28  

40          W

cross multiply so that 32W = (40*28)

then                                32W = 1,120

now divide by 32 on both sides

                                      32W = 1,120

                                      32          32      

so now it's only                W = 1,120/32

which simply equals        W = 35

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
