Since the base is 3 inches and the height is 4 inches, as well as the area of a triangle being base*height/2, we get 3*4/2=6 in. for each triangle. Since we need 20 pieces for each puzzle, we multiply 6 by 20 to get 120. In addition, since 80 puzzles are needed, with 20 pieces for each puzzle, we have 120 inches for each puzzle and 120*80 = 9600 square inches of wood used

Answer:
10.4
Step-by-step explanation:
Let the number be x
Sum of x and -3.2 : x + (-3.2) = x - 3.2
1/4 times the sum of a number and −3.2 = (1/4) * (x - 3.2)

x = 10.4
First, let's write down this inequality:
<span>There are at least 245 students enrolled in the school.
y≥245
This inequality says what the sentence says!
now, the number of teachers must be:
x≥2*(y/25)
(two times the number of groups of students of 25!)
so those two inequalities, taken together will be the answer!
