Answer:
10, 20
Step-by-step explanation:
x = larger number
y = smaller number
...
x = 10+y
5x=40+6y
...
Substitution of x into the second equation
5(10+y)=40+6y
50 + 5y = 40 + 6y
...
Isolate y
5y - 6y = 40 - 50
-y = -10
Divide both sides by -1
y=10 is the smaller number
...
Rearrange x = 10+y to y = x-10
Substitute into 5x=40+6y
5x = 40 + 6(x-10)
5x = 40 + 6x - 60
...
Isolate x
5x - 6x = 40 - 60
-x = -20
Divide both sides by -1
X=20 is the larger number

Answer:
7x+3y
Step-by-step explanation:
- Collect like terms
(3x+4x)+(-5y+8y)+(x^2-x^2)
2. Simplify
3x+4x=7x
-5y+8y=3y
x^2-X^2=0
So you get 7x+3y as your final answer
Answer:
The percent of increase over the original cost ($58) is 8.6%.
Step-by-step explanation:
The increase (markup) is $63-$58, or $5.
We find the markup (price increase) as follows:
$5
