Answer:
3x + 2 = 50
Step-by-step explanation:
The reason for this equation is that each friend gets 3 chocolates or 3x, x being the number of friends.
The 2 is the 2 chocolates that are left which can be subtracted from 50 on the other side to have the equation 3x = 48.
X would then equal to 16 people.
Answer:
1/2 ?
Step-by-step explanation:
Hi Braniac
S = his speed for the 1st 20 mi
(s-2) = His speed for the last 16 mi
We know that :
time= distance/ speed
initial time = cool down time
20/s = 16/(s-2)
Now cross multiply
20(s-2) =16s
20s-40=16s
20s-16s=40
4s = 40
Now we need to divide both sides by 4 so we can find the speed
4s/4 = 40/4
s= 10 mph
His initial speed is 10mph
Now let's find his cool down speed
10-2 = 8mph
His cool down speed is 8mph
I hope that's help :)
