The solution for this problem is just simple. It tells you to find the area in square feet. Thus, convert the units to feet first. The conversion you need to know are: 12 in = 1 ft and 3 ft = 1 yard.
Width = 42 in * 1 ft/12 in = 3.5 ft
Length = 10 yards * 3 ft/1 yard = 30 ft
Area = Length*Width = 30*3.5
<em>Area = 105 ft²</em>
Boys are b
Girls are g
b + g = 120
2g = b
Substitute the second equation into the first
2g + g = 120
3g = 120
g = 40
Plug in g = 40 and solve for b
b + g = 40
b + 40 = 120
b = 80
There are 40 girls and 80 boys.

Answer:
arithmetic sequence with d = 5
Step-by-step explanation:
The sequence is arithmetic if a common difference d exists between consecutive terms
d =
-
=
-
= ....
a₂ - a₁ = - 7 - (- 12) = - 7 + 12 = 5
a₃ - a₂ = - 2 - (- 7) = - 2 + 7 = 5
a₄ - a₃ = 3 - (- 2) = 3 + 2 = 5
Since there is a common difference of 5 between consecutive terms of the sequence, it is arithmetic
