Answer:
x=1 when y=2
Step-by-step explanation:
you could set up a proportion of 8/4 = 2/x.
cross multiply and you get 8x=8.
when you divide you get x=1
Answer:
9
Step-by-step explanation:
it's an isosceles right ∆.
so (9√2)^2 = 81*2= 162 = 2s^2
let x=y=s
s^2 = 81
s = 9
Answer:
X=3
Step-by-step explanation:
12x-31=5
12x - 31 - 31 = 5 + 31
12x = 26
12x / 12 = 26 / 12
x = 3
To solve the equation you take 31 to the right by subtracting it from the left then adding it to the right.
From there you divide each side by 12
