Answer:
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Answer:
36 kg
Step-by-step explanation:
Let m = mass of green tea.
The total mixture should be (18*3.5+2.6*m)/(18+m) = 2.9
The numerator is $, denominator is kg
Therefore 63+2.6m = 52.2+2.9m
0.3m = 10.8
3m = 108
m = 36
Answer:
Your missing a number and your answer is 12
Step-by-step explanation:
Answer:
- Lena's Method: 280
- Jackson's Method: 280
Step-by-step explanation:
Lena's Method:
- 8 + 12 = 20
- Plug 20 in: 14(20)
- 14(20) = 14 × 20 = 280
Jackson's Method:
- 14 × 8 = 112
- 14 × 12 = 168
- Re-write the expression: 112 + 168
- 112 + 168 = 280
I hope this helps!
