Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets
Answer:
12(n-3)
Step-by-step explanation:
Let
n -----> the number
1) The algebraic expression of "the sum of a number and negative 3" is equal to subtract 3 from the number
n+(-3)=n-3
2) The algebraic expression of "the product of 12 and the sum of a number and negative 3" is equal to multiply by 12 the sum of a number and negative 3
so
12(n-3)
I is a good friend and a good uuuuuuyyuyhyyytfikh..
You want the minimum of the solutions to
x + y = 24
7x - y = 16
There are many ways to solve these equations. Adding them together, you get
8x = 40
x = 5
Since this value is less than 12, it is the smaller number. The smaller number is 5.
