Step-by-step explanation:
120*10% =12
10% percent *120
= (10/100)*120
= (10*120)/100
= 1200/100 = 12
120 - 12 = 108.00 is original price of math text
Answer:
D.
Step-by-step explanation:
According to converse of the Pythagorean Theorem, that if the square of the third side (longest side) of a triangle equals the sum of the other two shorter sides, therefore, the triangle formed must be a right triangle.
From the side lengths given, the following satisfies the Pythagorean triple:
5² + 12² = 13².
Therefore, the procedure to use to confirm the converse of the Pythagorean Theorem would be to draw the two shortest side, 5 cm and 12 cm, so that a right angle will be between them. The side measuring 13 cm should therefore fit in to form a right triangle.
-2b + 7 > 27.5
- 2b > 27.5 - 7
- 2b > 20.5
b < - 10.25
Answer: a) w = -26, -2
b) x = -4, -1
c) k = 17, -1
d) z = 65, 935
Multiple choice: D)
Step-by-step explanation:
a) (w+26)(w+2) = 0
w = -26, w = -2
b) (x+4)(x+1) = 0
x = -4, x = -1
c) (k-17)(k+1) = 0
k = 17, k = -1
d) (z-65)(z-935) = 0
z = 65, x z 935
Multiple Choice
D)
Multiply all terms by 2.
