Answer:
?
Step-by-step explanation:
Car A Car B
d=rt d = rt
d = ra * 2.4 d = rb 4
ra = rb+22
distances are the same so set the equations equal
ra * 2.4 =rb *4
substitue in for ra
(rb+22) 2.4 =rb *4
distribute
2.4 rb +52.8 = 4 rb
subtract 2.4 rb from each side
52.8 = 1.6 rb
33 = rb
Car b travels at 33 miles per hour
Car a = 33+22
Car a = 55 miles per hour
Answer:
y =36
z= 54
Step-by-step explanation:
The angles 3y and 2y form a straight line, so they add to 180 degrees.
3y+2y =180
5y = 180
Divide each side by 5
5y/5= 180/5
y =36
The angles z, y, from a 90 degree angle
z+y =90
z+36 = 90
Subtract 36 from each side
z+36-36 = 90-36
z = 54
Answer:
9/4 x 16/5
=36/5
