I would help you but I can't see it maybe zoom in a little closer.
Answer:
x=1
y=-4
Step-by-step explanation:
4x+y=0 -> y= -4x
2(-4x)+x=-7
-8x+ x=-7
-7x=-7
x=-7/-7=1
y=-4 . 1 = -4
Ok so maybe add or subtract the numbers and see what u get :) I calculated it
Answer:
B. 1,188 cubic units
Step-by-step explanation:
First find the area of the base
A = 1/2b*h (this would only be half the base so our formula would be)
A = b*h (Now enter values)
A = (9)(6)
A = 54 (now plug this into the volume formula)
V = Ab * h
V = (54)(22)
V = 1,188 cubic units
Answer:
56 gallons
Step-by-step explanation:
When her gas tank is full, she has x gallons in the tank.
when she went to the gas station, she had (5/8) of x gallons of gas in her tank. she added 21 gallons into her tank, then she had x gallons in her tank.
(5/8)x + 21 = x
subtract x and 21 from both sides
(5/8)x - x = -21
factor out an x from the left side
x(5/8 - 1) = -21
simplify the parenthesis
x(-3/8) = -21
multiply both sides by -8/3
x= 56 gallons
