Answer:
10
Step-by-step explanation:
Since a rectangle has 2 sets of congruent sides we can set up the equation:
48=2x+2y
We have our x value/length (14) so we can plug that in to the equation.
48=2(14)+2y
Then we have to simplify
48=28+2y
20=2y
Then simply solve for the y value, which is your width
10=y
$420
Given that the students save$20 every week this can be written as;
1 week= $20 saved
For 21 weeks, you perform multiplication
1w=$20
21weeks=?------------perform cross multiplication
21*20=$420
-15 + (7-3) =
-15 + 4 =
-11
w = 15.5
31/2=15.5
The slope would be 1.75 because = = 1.75
