Answer:
Step-by-step explanation:
C
First number = X
Second number = 8X
Third number = X - 3
The equation would be
X + (8X) + (X - 3) = 207
X + (8X) + (X - 3) = 207
X + 8X + X - 3 = 207
10X - 3 = 207
10X = 207 + 3
10X = 210
X = 21
First number = 21
Second number = 8 * 21 = 168
Third number = 21 - 3 = 18
A 45°-45°-90° triangle has side lengths of "a" and a hypotenuse of "a√2"
Since the hypotenuse in youur problem is 6√2, then the side lengths are 6.
Answer: x = 6, y = 6
Step-by-step explanation:
7b-5b=-3+15
2b=12
b=12/2
b=6
