Answer:
Total = $49.05
Step-by-step explanation:
cost of grapes per pound = $ 2.50
she bought 3 pounds of grapes
so cost of 3 pounds of grapes = 3 × 2.50
= 7.5
gallon of milk = 8.6 pound
so cost of 8.6 pound of milk = 8.6 × 4.25
= $36.55
$ 1.50 off means =$4 - $ 1.50 = $2.5
cost of 2 boxes of cereal = 2 × 2.5
= $ 5
Total = 7.5 + 36.55 + 5
Total = $49.05
Answer:
Yes. This equation defines y as function of x.
Step-by-step explanation:
Step 1:
Solve the equation for y (this puts the equations in terms of y)
2x+y=8 becomes
y = 2x - 8
This is a linear equation, which is a funtion.
*Another way to solve this is to look at the graph. Graphing this equation gives us a line. Use the vertical line test to see if it's a function.
To pass the vertical line test (VLT), there can only be one y value to each x value along the graph. If it passes the VLT, the equation is a function.
If it fails the VRT, the equation is not a function.
Answer:the number of books that Sally sold is 21
Step-by-step explanation:
Jack sold 126 books. Joe sold 1/2 as many books as many books as jack. This means that the number of books that Joe sold would be
1/2 × 126 = 63
Sally sold 1/3 as many books as joe. This means that the number of books that Sally sold would be
1/3 × 63 = 21 books.
