Answer:
C = 20
Step-by-step explanation:
What happens if simultaneous Equations have two of the same variable like below? How would I solve it?
6A + 4B + 5C = 390
6A + 4B + 5.75C = 405
Step 1
We solve for C first
6A + 4B + 5C = 390....Equation 1
6A + 4B + 5.75C = 405... Equation 2
We substract Equation 1 from Equation 2
0.75C = 15
C = 15/0.75
C = 20
Total units of ratio = 1+4+5 = 10
Value of 1 unit = 180/10 = 18
It would be 1(18), 4(18), 5(18) = 18, 72 & 90
Answer:
42: 1,2,3,6,7,14,21,and 42
GCF of 42 & 15: 3
GCF of 42 & 50: 2
