Answer:
- sides: 12 feet
- front: 28 feet
Step-by-step explanation:
Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...
P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle
80 = 2(x + (2x+4)) . . . . . with values from the problem filled in
40 = 3x +4 . . . . . . . . divide by 2, collect terms
36 = 3x . . . . . . . . . subtract 4
12 = x . . . . . . . . . divide by 3. This is the length of the side fence.
2x +4 = 2(12) +4 = 28
The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)
Answer:
jumbo 23 oz, grande 16 oz
Step-by-step explanation:
Use g for grande and j for jumbo
The first equation: 28g + 33j = 1207
The second equation: 28g + 53j = 1667
Subtract the first from the second
28g + 53j = 1667
- 28g + 33j = 1207
Equal 20j = 460
j = 23
Put 23 in for j in either equation and solve for g:
28g + 33(23) = 1207
28g + 759 = 1207
28g = 448
g = 16
Answer:
Part A: 2k(2c2+5(2)-8c-20)
Part B: sorry i don't know how to do this part
Step-by-step explanation:
Part A, you divide each number by 2 first so you get a simplified version of each number. Then, you will quickly realize that the varible k is similar in all of the numbers then you remove that and put it with the 2 outside the (). Hope you understood my explination.
7+3=4+6 Both numbers equal 10
