Answer:
The number of adults, a, is 300, and the number of kids, k, is 200
k + a = 500 (1)
3k + 10a = 3,600 (2)
Then Multiply both sides of equation (1) by -3
(k + a) • -3 = 500 • -3
-3k − 3a = -1,500
Now, add this equation to equation (2)!
3k + 10a = 3,600
+ -3k − 3a = -1,500
7a = 2,100
a = 300
And last Substitute the value of a into equation (1).
k + a = 500
k + 300 = 500
k = 500 – 300
k = 200
Answer: I got 76.
Step-by-step explanation:
Ok, lets start with the top.
7/8 + (-2/3)
Thats equal to
7/8 - 2/3
The common denominator will be 24
21/24 - 16/24
Subtract
5/24
Now, to divide you multiply by the reciprocal, so
5/24 / 5/6
Becomes
5/24 * 6/5
Cross simplify and get your answer
1/4
