Which variable are we solving for?
For y:
y= 5x-4/ 13
For x:
x= 13y+4/ 5
Answer:
1st question: M=22.62 while C=75.38
2nd question: M=.22 while C=1.97
Step-by-step explanation:
If a mirror costing x dollars is marked up 30%, then we have to find x such that 30%x+x is 98 dollars.
We are solving:
.3x+x=98
Combine like terms:
1.3x=98
Divide both sides by 1.3:
x=75.38
M=98-75.38=22.62
C=75.38
So M=22.62 while C=75.38.
If ream of paper cost x and is marked up 11%, then we have to find x such that 11%x+x is 2.19.
We are solving:
.11x+x=2.19
1.11x=2.19
x=1 97
M=2.19-1.97=.22
So M=.22 while C=1.97
Answer: 4.25
divide 4 on both sides, and it should leave you with x = 4.25
your welcome :)
Answer:
the aswer is 4/-5 :)
Step-by-step explanation: (2,1) and (-3,5)
m=y2-y1
x2-x1
m= 5-1 4
-3-2 = -5
The slope is 4/-5 or- 0.8
Hope this help :)
The answer is standard form. When the equation is set up as Ax + By = C where A and B are coefficients.
