I believe its C
Step-by-step explanation:
My bad if im wrong tho
Y=<span>5 is your answer. Hope this helps :)</span>
x/110 = (320-x)/90
<span> Cross multiply</span>
90x = 35200-110x
200x=35200
X = 35200/200 = 176 (distance traveled by train going 110 mph
176/110 = 1.6 hours = 1 hour and 36 minutes
Check: 110*1.6 = 176, 90*1.6 = 144
176+144 = 320
it will take 1.6 hours ( 1 hour 36 minutes) for the trains to meet
The standard form of thr number is 11.651
Answer:
6
Step-by-step explanation:
Find the missing angle:
180⁰ - 82⁰ = 98⁰
Find the sum of the angles given without the missing angle:
180⁰ - 98⁰ = 82⁰
The sum of both the angles is 82⁰
Write an equation:
5x + 8 + 6x + 8 = 82⁰
Collect the like terms together
11x + 16⁰ = 82⁰
Subtract 16⁰ from both sides
11x = 66⁰
Divide by 11 on both sides
x = 6⁰
