Answer:
B
Step-by-step explanation:
If you look at A and you subtract 3x by 4x you get x and you subtract 3 from -7 and you get -10. But if you look at B you do the stuff in the parentheses first and you get 4x+12x+28=16x+28 and they're the same so it's B.

Answer:
<em> 5 1/2 weeks </em>
Step-by-step explanation:
Given
Time it will take to complete the building = 85 1/4 hrs
Time he works on the house weekly = 15 1/2 hours
This can be expressed as
1 week = 15 1/2 hours
To calculate the number of weeks it will take to complete the house, we will say:
x = 85 1/4
Cross multiply
15 1/2 x = 85 1/4
31/2 x = 341/4
31x/2 = 341/4
Cross multiply again
31x * 4 = 2 * 341
124x = 682
x = 682/124
x = 5.5weeks
<em>Hence it will take Ryan 5 1/2 weeks to complete the house</em>.
