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
3.14 by 3.57 just divide those numbers by 14 and round to the hundredths place
Answer:
12 units²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 4 ( perpendicular distance between the bases ) and
b₁ = SR = 2, b₂ = TA = 4 , then
A = × 4 × (2 + 4) = 2 × 6 = 12 units²
Answer:
M = 2620 + 16d
M = total money paid or earned
d = # of days
Step-by-step explanation:
15 food
23 game
Total Money = M = 15 * 75 + 9 d + 23* 65 + 7d
M = 15 * 75 + 9 d + 23* 65 + 7d
M = 1125 + 1495 + 16d
M = 2620 + 16d
