Answer:
The equation is 0.11x + 0.25 = 0.15x (I think) and the answer is 6.25 = x
Step-by-step explanation:
0.11x + 0.25 = 0.15x Subtract 0.11x from both sides
-0.11x -0.11x
0.25 = 0.04x Divide both sides by 0.04
6.25 = x
Answer:
x = 2
Step-by-step explanation:
To solve the equation, you need to set both functions equal to each other and simplify to find the value of "x".
f(x) = 2x + 1
g(x) = -x + 7
f(x) = g(x) <----- Given equation
2x + 1 = -x + 7 <----- Insert functions
3x + 1 = 7 <----- Add "x" to both sides
3x = 6 <----- Subtract 1 from both sides
x = 2 <----- Divide both sides by 3
Answer:
Percent of rise of a new truck on a used truck = 15%
Step-by-step explanation:
Let x be the percentage of saved money if Jason buying a used truck.
Given:
Price of the used truck = $34,000
Price of the new truck = $40,000
We need to find the percent of rise Jason saves on a used truck rather than buying a new truck
Solution:
Using a percentage formula.
![percentage\ cost = \frac{(100-x)}{100}\times Original\ cost](https://tex.z-dn.net/?f=percentage%5C%20cost%20%3D%20%5Cfrac%7B%28100-x%29%7D%7B100%7D%5Ctimes%20Original%5C%20cost)
Substitute Percentage cost = 34,000 and Original cost = 40,000 in above formula.
![34000 = \frac{(100-x)}{100}\times 40000](https://tex.z-dn.net/?f=34000%20%3D%20%5Cfrac%7B%28100-x%29%7D%7B100%7D%5Ctimes%2040000)
(
)
Using cross multiplication rule.
![(100-x)=\frac{34000}{400}](https://tex.z-dn.net/?f=%28100-x%29%3D%5Cfrac%7B34000%7D%7B400%7D)
![85=100-x](https://tex.z-dn.net/?f=85%3D100-x)
![x = 100-85](https://tex.z-dn.net/?f=x%20%3D%20100-85)
x = 15%
Therefore, Jason used 15% rise of a new truck for a used truck.
