Answer:
Number of people who order chicken dinner = 1
Number of people who order the steak dinner = 5
Step-by-step explanation:
Let
x = number of people who order chicken dinner
y = number of people who order the steak dinner
x + y = 6 (1)
14x + 17y = 99 (2)
From (1)
x = 6 - y
Substitute into (2)
14x + 17y = 99 (2)
14(6 - y) + 17y = 99
84 - 14y + 17y = 99
- 14y + 17y = 99 - 84
3y = 15
y = 15/3
y = 5
Substitute y = 5 into (1)
x + y = 6 (1)
x + 5 = 6
x = 6 - 5
x = 1
Number of people who order chicken dinner = 1
Number of people who order the steak dinner = 5
Answer: the second one, the third one, and the fifth
Step-by-step explanation:
I am almost certain that is correct, but don't quote me on it
Answer:
i think its either a or b
Step-by-step explanation:
7x+5+8x
combine 7x and 8x to get 15x+5
m = 7.5x+2.5 would be the exact middle, but without knowing x I can't help much more. My school's work usually tells me x.
Children : 144
Adults : 51
Explanation
Step 1
Set the equations
let
x represents the number of children
y represents the number of adults
charge per child:8
charge per adult:11
total people:195
then
a)the total people is 195, so
b) the total bill was $1713,so
total childrend +total adults=173
but,
total adults cost= rate*number of adults
total children cost= rate*number of childe
replacing
Step 2
solve the equations,
a) isolate the x value from equation 81) and replace in eqaution (2)
replace in equation (2)
therefore, the number of adults is 51
b) now, replace the y value into equation (1) to find x
so, the number of children is 144
I hope this helps you
