9435 pounds in great food warehouse
6555.569 pounds in Tasty warehouse
How many more pounds are needed in Tasty warehouse to have the same as Great foods warehouse?
Find the difference and that is how many pounds are needed.
A. Let x represent the number of miles and y represent the total price.
y=3x+15
B. Using the equation we just wrote, replace the x with 45.
y=3(45)+15
Now multiply 45 by 3.
y=135+15
And finally add together 135 and 15.
y=150
The total cost of a 45 mile taxi ride would be $150.00.
Answer:
x ≈ -0.90, y ≈ 2.31
x ≈ 1.40, y ≈ 9.19
Step-by-step explanation:
Easiest and fastest way to do this is to graph the systems of equations and trace where the graphs intersect:
The answer is c because 19-27 is equal to 19+(-27)
To figure this out use keep change change
Keep the original sign of the first # (19) then make the sign it’s opposite (- =+) then change the sign of the next # (27= -27)
