Answer:
$2925
Step-by-step explanation:
To find the cost, we need to get the area of the triangular sale. This can be obtained by using the area of a triangle.
This is A = 1/2 * b * h
Where in this case, b = 12ft and h = 25ft
The area is thus 1/2 * 12 * 25 = 150sq.ft
Now we know that 1sq.ft is $19.50, 150 will be 150 * 19.5 = $2925
Answer:
Step-by-step explanation:
drama+yearbook=64
drama=10 more than yearbook
drama=10+yearbook
the equations are
x+y=64
x=10+y
solve
subsitue 10+y for x
10+y+y=64
10+2y=64
minus 10 both sides
2y=54
divide both sides by 2
y=27
subsitute back
x=10+y
x=10+27
x=37
