Answer:
-9>2x+15
Step-by-step explanation:
Step-by-step explanation:
-3x + 7y = 5x + 2y (you subtract the 2y from both sides)
-3× + 5y = 5x (then add 3x to both sides)
5y = 8x (use x = - 5)
5y = 8x - 5 = -40 (both sides are divided by 5)
y = -8
answer is (-5, -8)
17/2, 8 and 1/2 or 8.5 are all the correct answers.
C.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 77, -77
Answer:
this means that lot 1 would have more cars. there were 3 cars in lot 1 and 2 in lot 2
Step-by-step explanation:
lot 1- lot 2-
3:4 2:3
if both have 12 trucks, you need to multiply the number of cars with the number you used to make the trucks 12
3:4 would turn into 9:12
2:3 would be 8:12
this means that lot 1 would have more cars. there were 3 cars in lot 1 and 2 in lot 2
