Answer:
![b = \frac{7}{12}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B7%7D%7B12%7D)
Step-by-step explanation:
![b + \frac{2}{3} = 1\frac{1}{4}\\\\b = 1\frac{1}{4} - \frac{2}{3}\\\\b = \frac{5}{4} - \frac{2}{3}\\\\b = \frac{5(3)}{4(3)} - \frac{2(4)}{3(4)}\\\\b = \frac{15}{12} - \frac{8}{12}\\\\b = \frac{7}{12}](https://tex.z-dn.net/?f=b%20%2B%20%5Cfrac%7B2%7D%7B3%7D%20%3D%201%5Cfrac%7B1%7D%7B4%7D%5C%5C%5C%5Cb%20%3D%201%5Cfrac%7B1%7D%7B4%7D%20-%20%5Cfrac%7B2%7D%7B3%7D%5C%5C%5C%5Cb%20%3D%20%5Cfrac%7B5%7D%7B4%7D%20-%20%5Cfrac%7B2%7D%7B3%7D%5C%5C%5C%5Cb%20%3D%20%5Cfrac%7B5%283%29%7D%7B4%283%29%7D%20-%20%5Cfrac%7B2%284%29%7D%7B3%284%29%7D%5C%5C%5C%5Cb%20%3D%20%5Cfrac%7B15%7D%7B12%7D%20-%20%5Cfrac%7B8%7D%7B12%7D%5C%5C%5C%5Cb%20%3D%20%5Cfrac%7B7%7D%7B12%7D)
Answer:
m = 13
Step-by-step explanation:
To isolate the variable, you undo what is being done to it. Here, we have the variable being multiplied by 7, hence, we divide both sides by 7 and the result is the variable isolated and solved.
1. 7m = 91
2. (7m)/7 = 91/7
3. m = 13

Answer:
C = $137.50
Step-by-step explanation:
Okie dokie, so we already know he charges $50 just for a service call, plus 25 per hour, so let's say the total charge is C.
Now, let's make an equation:
C = 50 + 25(3.5)
Now, multiply 25 and 3.5 together:
C = 50 + 87.5
Now we just combine the like terms:
C = $137.5
Hope this helps :)
If he uses 100 inches of wood to make the frame, then 100 is double the sum of the length and the width, so 50 is the sum of the length and the width.
If the length is 12 more than the width, then the width is (50-12)/2=19. The length, then, is 19+12=31.
