Answer:
25
Step-by-step explanation:
look B=C
so,
A+B+C=180 Sum of all <s of Tri
x+5+3x+3x=180
7x=175
x=175÷7
x=25
The slope (m) is -4 , and the y-intercept (b) is 8. Slope intercept form is y = mx+b
Y=-4x+8
Answer:
If the first one, 10x² - 10x - 60. For the second one, -5x - 30
Step-by-step explanation:
10(x + 2)(x – 3)
10(x²- x -6)
10x² - 10x - 60
5(2 – 3)(x + 6)
5(2x + 12 - 3x -18)
5(-x -6)
-5x - 30

Answer:
8.5 h = 510 min
Step-by-step explanation:
An hour is equal to 60 minutes. Half an hour is 30 minutes.
We can break "8.5" into 8 hours and 0.5 of an hour (which is 30 minutes).
Knowing this, we can multiply 8 by 60 since each hour is 60 minutes. We then get 480. We still need to add the remaining 0.5 of an hour (30 minutes) so we add 480 + 30. We then get 510.
Therefore 8.5 hours = 510 minutes. Hope this helps!
