Answer:
Width = 10 feet
Length = 15 feet
Step-by-step explanation:
Let the width = x feet
Length = x + 5
Perimeter = 50 feet
2 * ( length + width) = 50
2 * (x+5 + x) = 50
2x + 5 = 50/2
2x + 5 = 25
2x = 25 - 5 = 20
x = 20/2 = 10
Width = 10 feet
Length = 10 + 5 = 15 feet
i = 3c
i = c + 14
set both equations equal to each-other, we can
solve for c, we must.
3c = c + 14
subtract c from both sides, we must.
2c = 14
divide both sides by 2, we must.
c = 7
7 years old, Christopher is.
For shop smart, the price is 48 packs for 9 dollars so you would divide
9 ÷ 48 to find the price for dollars per can which is 19 cents per can
for super save it's saying 48 packs for 10 dollars so divide
10 ÷ 48 and that is 21 cents per can
for price buster it's saying 36 packs for 9 dollars so you would divide
9 ÷ 36 which is 25 cents per can
so Mei Pilar and David should purchase the cans at shop smart since it's cheaper
Perimeter of triangle = all sides added up
3a + 4 + 2a - 7 + 9a + 11
now add like terms
3a + 2a + 9a = 5a + 9a = 14a
4 - 7 + 11
= -3 + 11 = 8
so we have 14a + 8
as our simplest expression
