Fun. It took Joelle 1/4 hour to get there. It took Andrea 1/2 hour and Kellan 3/4 hours.
Their distances are simply rate times time,
j = 35(1/4) = 35/4 = 8.75 miles
a = 3(1/2) = 1.5 miles
k = 14(3/4) = 21/2 = 10.5 miles
Answer: 10.5 miles
Next part. It took Kellan 12/15=4/5 hour to bike to Andrea.
Let's assume it's the same restaurant. They had to walk 1.5 miles, which they did at 2.5 mph, 1.5/2.5=3/5 hours.
So Keelan traveled for 4/5+3/5=7/5 hours, which is 1 hour, 24 minutes.
They got there 5 minutes early, 8:55, so Keelan left at 7:31 am
Answer: 7:31
Answer:
3
Step-by-step explanation:
-8x+40=-6x+34
-8x+6x=34-40
-2x=-6
x=6/2
x=3
Brazil population: 1.907×
Mexico population 1.123×
To find how much more the population was in Brazil than in mexico, you would subtract the Brazil population to Mexico's population:
The 's would not cancel out because they are representing further decimal places that aren't written, so you would subtract 1.907 and 1.123.
1.907 - 1.123= 0.784
Brazil's population is 0.784× larger than Mexico.
fog(x+2) = f(g(x+2) = f ( x+2+7)
= f(x+9)
= x+9- 4
(f g)(x + 2) = x+5
I believe the answer is x>1.
