13x + 47 = 151
subtract 47 from both sides
13x = 104
divide by 13 on both sides
x = 8
Answer:
Plane 1 travels 20 miles farther than plane 2 in an hour.
Step-by-step explanation:
To compare the distances, compare the speed of each plane. The speed of plane 1 is 290 miles per hour in d(t) = 290t.
Plane 2 travels 540 miles over 2 hours. Its speed is 540/2 = 270 miles per hour.
Plane 1 will travel 20 miles farther than plane 2 in an hour.
Answer:
Step-by-step explanation:
354 Students TOTAL.. If 4 of those students rode in a car, then there is 350 kids divided up to fit inside 7 buses. So divide 350 by 7. The answer is 50 Students rode in each bus.
If the legs of a right triangle are a and b and the hypotnuse is c then
a²+b²=c²
so we are given
the legs are x and √7
and the hypotnuse is √19
so
x²+(√7)²=(√19)²
x²+7=19
minus 7 both sides
x²=12
sqrt both sides
x=√12
x=√(4*3)
x=(√4)(√3)
x=2√3
