Answer: 24; 8.5
Step-by-step explanation:
40% of 60
Move the decimal twice
4*6= 24
17% of 50
Move decimal and multiply
0.17*50= 8.5
Substitute on equation 2, y = -4x + 7. so equation 1 becomes 2x - (-4x + 7) = 6x - 7 = 5. 6x = 12, so x = 2. from above, y = -4x+7 = -4(2) + 7 = -1
Answer:
A, C
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
Midpoint B of segment AC creates both equal segments AB and BC. The midpoint halves out AC therefore AB=BC
The equation would look like 2x-5=x+7 where you want to isolate x fully. First you want to add 5 on both sides of the equation so that you get 2x=x+12. Next subtract x from both sides of the equation to then get x=12.
Since the truck adds 22,000 PER YEAR, this would be the number we multiply by the variable depending on how many years they are calculating for. So we have y = 22,000xThe truck already has 40,000 miles on it so it s STARTING at 40,000, this is our y-intercept, or b.Now we have y = 22,000x + 40,000
