Answer: you travelled 10 km
Step-by-step explanation:
Pam jogged up the hill at 6 km/h.
Let x represent the number of kilometers that you travelled by jogging up the hill or returning back.
Time = Distance/speed
Pam jogged up the hill at 6 km/h.
Time spent in jogging up the hill would be
x /6
She then jog back down the hill at 10 km an hour. Time spent in jogging down the hill would be
x /10
If the total jogging tie is 1 hour 20 minutes, converting to hours, it becomes 1 + 20/60 = 1.33
Therefore
x /6 + x/10 = 1.33
10x + 6x = 80
16x = 80
x = 80/16 = 5
Total distance travelled up and down the hill would b
5 × 2 = 10 km
Answer:
15 girls, 10 boys
Step-by-step explanation:
Since the ratio is 3:2, then the ratio can be rewritten as 15:10. So there are 15 girls and 10 boys
slope=y2-y1/x2-x1
5-2/3-2
denominator will show 3-2
Answer:
Option C
Step-by-step explanation: I think this is right because when you substitute the 2 for x you get the answer. Hope this helps darling!!
Answer:
No Solutions.
Step-by-step explanation:
original equation
3x+13 = 3(x+6)+1
distribute 3
3x+13 = 3x+18+1
simplify
3x+13 = 3x+19
since the slope is the same for both equations and the y-intercept is different the two equations are parallel meaning they will never intersect so there are no solutions.
