Answer: d = 147/4 or 36.75
Edward didn't isolate for 'd' by rearranging the terms.
(4/7)d = 21 (Multiply both sides by 7 to get rid of the 7 on the left side)
4d = 21 · 7
4d = 147 (Divide both sides by 4 to isolate for d)
d = 147/4 or 36.75
Answer:
$5.50
Step-by-step explanation:
k lets say x=movies while y=games
so, lets make a system of equations
2x+3y=14.50
3x+y=9.50
you can do substitution or elimination here it doesn't matter but you get x=2; y=3.5
movies cost 2 bucks, while games cost $3.50
so total is 3.50+2

Answer:
Step-by-step explanation:
(-4+12)/2 and (14-6)/2
= (4,4)
Assuming that your own ticket is already secured.
From the 5 friends you can only choose 3.
The order in which these friends are chosen is not relevant. So this is a Combination problem.
Where the order is relevant the problem becomes a Permutation problem!
So the answer is 5 combination 3. = ⁵C₃
⁵C₃ = (5 * 4 * 3) / ( 3 * 2 * 1) = 10
You can take 10 groups of any 3 of your 5 friends.
