Answer:
40 ft squared
Step-by-step explanation:
to find the area of a triangle, you do base x height divided by 2
5 x 16 = 80
80 divided by 2 is 40
4%n = 5
Simplify the equation
1/25n = 5
Multiply by 25
25 (1/25n) = (25) (5)
n = 125.
Answer:
I did it and is 36
Step-by-step explanation:
Answer:
X = -2
Step-by-step explanation:
1/2 X (5X-8) = -9
multiply both sides of the equation by 2
2 X 1/2 X (5X - 8) = 2 X (-9)
1 X (5X - 8) = 2 X (-9)
Reduce the numbers with the greatest common divisor 2
5 x -8 = 2 x (-9)
5 x -8 = -18
Move constant to the right by adding its opposite to both sides
5X -8 + 8=-18 + 8
Then eliminate the opposites
5X = -18 + 8
Calculate the sum
5X = -10
Divide both sides of the equation by 5
5X DIVIDE 5 = -10 DIVIDE BY 5
X = -10 DIVIDE BY 5
X = -2
