Answer:
Step-by-step explanation:
I don't see the choices, but I will make the equations that seems to be correct to me.
Known facts:
- maintained an average speed of 35 miles per hour (mph) for the first m hours of her road trip.
- next n hours of the trip, she drove at an average speed of 60 mph.
- Eva drove a total of 225 miles in 4.5 hours.
Let's make the equations:
m + n = 4.5
35m + 60n = 225
Hope that helps!

Answer:
<H = 40
Step-by-step explanation:
Complementary angles add to 90 degrees
2x+10 + x+20 = 90
Combine like terms
3x+30 = 90
Subtract 30
3x+30 -30 = 90-30
3x = 60
Divide by 3
3x/3 = 60/3
x = 20
<H = x+20 = 20+20 = 40
