Find the values for a, b, c, and d. can you make a proportion using your results? how many different proportions can be made? a = 3.6·( 3 4 + 2 9 + 5 12 ) b = (84.8·0.125)÷(10.07÷0.95) c = (1 5 12 − 2 3 )÷0.15+ (14−0.14)÷0.014 99 d = 0.28·4,500÷35· 1 12

A=5

B=1

C=15

D=3

Step-by-step explanation:you just do the calculations

for b, tho u can look at the other numbers and find out a working proportion that's a multiple of 10. (yes, i had this problem too!)

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
