Answer:
![w = \frac{11}{35}](https://tex.z-dn.net/?f=%20w%20%3D%20%5Cfrac%7B11%7D%7B35%7D%20)
Step-by-step explanation:
To solve,
, make both fractions on your left as one fraction by finding a common denominator.
Common denominator of 5w and 7w is 35w
Thus,
![\frac{7(3) -5(2)}{35w} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%283%29%20-5%282%29%7D%7B35w%7D%20%3D%201%20)
![\frac{21 - 10}{35w} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B21%20-%2010%7D%7B35w%7D%20%3D%201%20)
![\frac{11}{35w} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B35w%7D%20%3D%201%20)
Multiply both sides by 35w
![\frac{11}{35w}*35w = 1*35w](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B35w%7D%2A35w%20%3D%201%2A35w%20)
![11 = 35w](https://tex.z-dn.net/?f=%2011%20%3D%2035w%20)
Divide both sides by 35
![\frac{11}{35} = \frac{35w}{35}](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B35%7D%20%3D%20%5Cfrac%7B35w%7D%7B35%7D%20)
![\frac{11}{35} = w](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B35%7D%20%3D%20w%20)
![w = \frac{11}{35}](https://tex.z-dn.net/?f=%20w%20%3D%20%5Cfrac%7B11%7D%7B35%7D%20)
Answer:
18 rungs
Step-by-step explanation:
Let x = number of rungs
x/2 = middle
Climbed 3
x/2 +3
Down 5
x/2 +3 -5
Climbed 9
x/2 +3 -5+9
Then climbed 2 more
x/2 +3 -5+9 +2
Now is at the top
x/2 +3 -5+9 +2 =x
Combine like terms
x/2 +9 = x
Subtract x/2 from each side
x/2+9-x/2 = x - x/2
9 = x/2
Multiply each side by 2
18 =x
C. The demand for gasoline will be unaffected and the effect in supply is uncertain
Answer:
p * 90 = 36
p = 40%
Step-by-step explanation:
To find the percentage of sandwiches that are pastrami, multiply the percentage(p) by the total amount of sandwiches(90) and set it equal to the amount of pastrami sandwiches(36):
p * 90 = 36
To find the value of p, divide both sides of the equation by 90 to isolate p:
90p/90 = 36/90
p = 0.4
0.4 is the decimal form of 40%.
Hope this helps :)
