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:
70*20=1400/2= 700. that's all
Answer:
the answer is B.
Step-by-step explanation:
let me know if I'm wrong.
Lets rewrite this into point-slope, y=mx+b.
y-8=7(x+3)
y-8=7x+21
y=7x+29
Now we can find the slope, which is 7. Now, because this is a linear line, we can substitute points to find which answer is correct.
Option A)
(8)=7(-3)+29
8=-21+29
8=8 TRUE
Option A is correct,
<span>slope: 7
point: (-3, 8)</span>

Catie : 15 + 8x page
23 + 7x = 15 + 8x
get x = 8 (days)
and the final page is 79
