3^3 / 3^1 = 3^2 is my example
That would be C.
20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10
now in y = mx + b form. the m represents ur slope and the b represents ur y intercept. So here, u have a slope of -4 and a y intercept of 10.
Answer:
x = 49/23
Step-by-step explanation:
23x=49
Divide each side by 23
23x/23 = 49/23
x = 49/23
The correct answer is The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
Hope this helped! :)

Answer:
PE = 83 and Science = 71
Step-by-step explanation:
let P represent PE and S represent Science with P > S, then
P + S = 154 → (1)
P - S = 12 → (2)
Adding the 2 equations term by term eliminates S
2P = 166 ( divide both sides by 2 )
P = 83
Substitute P = 83 into (1)
83 + S = 154 ( subtract 83 from both sides )
S = 71
Hence PE mark = 83 and Science mark = 71
