Each side of the square is 16 ft
Answer:
$0.5
Step-by-step explanation:
Given data
Cost of 5 pencils= $2.50
Required
The cost per pencil
The cost per pencil is
Cost of 5 pencils divided by 5
=2.5/5
=$0.5
This is the constant of proportionality
For any number of pencils x
The cost is
Cost =0.5x
Hence the cost of one pencil is $0.5
Answer:
1. $6000
2. 40.9%
3. 51.6%
4. Misc
Explained :
1. 1800 + 150 + 2450 + 1300 + 300 = 6000
2. 2450/6000 = 0.409 = 40.9%
3. 1800 + 1300 = 3100 ; 3100/6000 = 0.516 = 51.6%
4. 300/6000 = 0.005 = 5%
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
