Answer:
120 = 3y + t
Step-by-step explanation
because you purchase 3 times as many y then t. Overall, your answer should end up as 120 by using an equation like this.
Answer:
<u>x=10</u>
Let's solve your equation step-by-step:
4x+40=80
<em>Step 1: Subtract 40 from both sides</em>
4x+40−40=80−40
4x=40
<em>Step 2: Divide both sides by 4</em>
4x/4=40/4
Answer:
<u>x=10</u>
Answer:
Dilation factor is 2/3
Step-by-step explanation:
Look at both flat lines (M to S and M' to S') and find their lengths.
M to S = 9 units
M' to S' = 6 units
The triangle has gotten smaller so the dilation factor is a fraction
new/original = 6/9 = .66666666 or 2/3
Dilation factor is 2/3
Answer:
The speed and time are directly proportional in that the higher the speed the lesser the time and vice versa.
The constant is the total distance which is 180 km
Step-by-step explanation:
Step one:
given data
The distance between the two cities is 180km
1.The distance was covered by a car at the rate of 50km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/50
time= 3.6 hours
2.The distance was covered by a bus 45km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/45
time= 4 hours
3.The distance was covered by a bicycle at 25km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/25
time= 7.2 hours
