Answer:
speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively
Step-by-step explanation:
Given: Juan's time in the race was 5.04 seconds and Tiauna's was 5.40 seconds
Let speed of Juan and Tiana's be J m/s and T m/s respectively
In the race both Juan and Tiauna will cover equal distance. Therefore, the speed and time would have reciprocal relationship
Speed ∝ 1/Time
This means J = 1/5.04 m/s
J= 0.1984 m/
and, T = 1/5.40 m/s
T= 0.1851 m/s
Therefore, speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively
B- $7.50. Take 30 and divide it by 4, and you get your weekly subscription cost.
Step-by-step explanation:
We need to solve 5x+10=25 ....(1)
Step 1.
Subtract 10 to both sides of the above equation.
5x+10-10=25-10
5x=15
Step 2,
Divide each side by 5.
If we want to check whether it is correct or not, step are as follows :
Put x = 3 in equation (1)
5(3)+10=15+10
=25
It means that the above steps are correct.
