Hello,
Answer A
d :the distance in miles
t: the time in hours
v: the speed in miles/hours (vistesse)
d=v*t
==>d=40*4=160(mi)
d=55*x=160==>x=160/55=2.909090... (mi/(mi/h)=h)≈2.91(hours)
Answer:
The m∠5 (measure of angle 5) is 135°.
Step-by-step explanation:
The m∠1 is equal to 135°. Since ∠1 and ∠5 are alternate exterior angles, they will be congruent.
I think none of these are right. It's Y=-5/3x +4/3
Assuming 5a3 equals 5a^3, and the same for everything else, you would plug in 4 for a, so 5(4)^3 - 2(4)^2 + 4 - 45, which equals 247.
