Answer:
25m + 10b = 400
Step-by-step explanation:
Total amount that can be earned = $ 400
Amount earned on mowing a lawn = $ 25
Amount earned per hour on babysitting = $10
Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m
Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b
Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours
Using the values from above, we can set up the equation as:
400 = 25m + 10b
or
25m + 10b = 400
This equation represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.
If i understand you are wanting to find the value of g
so if 2/5 of the unkown value g is equal to -14 you would find out that 1/5 g would be -7 so to find g you times -7 by 5 and get -35
g= -35

Step-by-step explanation:
Answer:
The coin was thrown from 448 feet
Time to hit the ground is 7 seconds
Step-by-step explanation:
Given

Solving (a): Height when coin is thrown
At this point t = 0
So, we have:

Solve expressions in the brackets


<em>Hence, the coin was thrown from 448 feet</em>
Solving (b): Time to hit the ground
At this point, h = 0.
So, we have:

Reorder

Divide both sides by -16

This gives:
or 
or 
Since, time can't be negative;
