Each table is 3 seats long and 1 seat wide. If you push 3 tables together, end to end, they become 9 seats long, and remains 1 seat wide. If you add up the perimeter, it comes out to 9+9+3+3, which is 24.

vaieri [72.5K]

Let's assume

the number of bags of candy =x

the number of bags of cookies =y

There were 5 more bags of cookies sold than candy

so, we get

y=x+5

Bags of candy cost $5.50

so, total cost of candy is

=5.50x

bags of cookies cost $3.50

so, total cost of cookies is

=3.50y

so,

total cost = (total cost of candy)+(total cost of cookies)

we get

total cost =5.50x+3.50y

so, we can plug

5.50x+3.50y=53.50

now, we can plug y

5.50x+3.50(x+5)=53.50

5.5x\cdot \:10+3.5\left(x+5\right)\cdot \:10=53.5\cdot \:10

55x+35\left(x+5\right)=535

55x+35x+175=535

90x+175=535

90x+175-175=535-175

90x=360

x=4

now, we can find y

y=x+5

y=4+5

y=9

so,

the number of bags of candy =4

the number of bags of cookies =9............Answer

Why can't you have a shoe size of 4.5 and a height of 72 inches?
liq [111]

Answer:

Ok, lemme say something.

4.5 shoes are for 9 inch feet.

Dont think a 6 foot person is gonna fit tbh.

Step-by-step explanation:

A shoe size is for relation to feet size. Your feet grow from your height too, along with weight. If you are 6 feet, your feet are gonna be more than at least 1 foot.

4.5 shoes are for 9 inch feet

1 foot = 12 inches.

12 > 9.

12-9=3.
