Since those lines are parallel, we know that A + B = 180°
So, we have:
8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 180 - 130
10x = 50
x = 5
B = 2x + 56
B = 10+56=66
(To check:
A = 8x + 74
A = 40+74=114
114+66=180)
The constant variation of y=15x is 15 and the constant variation of y=8x is 8 :)
I think I would set a proportion for this. 1 1/2 hours is 90 minutes. So 90 minutes and 90 miles.
90 300
—- = ——.
90 X
As you can see, miles on top and minutes on the bottom. Now, cross multiply. 90x = 300(90)
90x=27,000
Divide by 90 on both sides to get x alone.
90x/90= x 27,000/90=300
300 minutes would be 5 hours!
Answer:
1/64
Step-by-step explanation:
If the denominators are the same an the top number is 1 then you can just multiply them.
