Answer:
a. 81.9
b. 144.7
c. 110.2
d. 48
Step-by-step explanation:
a. 120/109.2 = 90/x
x = 81.9
b. 45.6/120 = 55/x
x = 144.7
c. 304.8/96 = 350/x
x = 110.2
d. 109.2/45.6 = 115/x
x = 48
Answer:
x=3, y=2
Step-by-step explanation:
To solve by elimination method, multiply one of the equation by a constant such that when you subtract one equation from the other, you are left with one term only.
X+1=10
move +1 to the other side
sign changes from +1 to -1
to get X by itself
X+1-1=10-1
X=10-1
Answer:
X=9
