Answer:
1. Expression can be rewritten as 
and 
2. The expression for total cost for a visit = 
and the Total Cost to visit the fair for 20 tickets is 
3. B. 
Step-by-step explanation:
1. Solving for first Question
Given expression are 
and 
Solving equation we get,
Expression can be rewritten as and
2. Solving for 2 Question
Given
Fixed cost of carnival = 
Additional Cost per ticket for food and ride = 
represents number of tickets.
Total cost to visit carnival = Fixed cost of carnival + Additional Cost per ticket for food and ride
Number of tickets = 
algebraic expression to represent the total cost for a visit to the carnival =
Now Number of tickets sold n = 20
Total cost to visit carnival= 
Total Cost to visit the fair for 20 tickets is
3. Solving for 3 question.
Given :
Solving Above equation we get:
Hence the answer is B.
Answer:
x = 7; y = 11
Step-by-step explanation:
AB = x
AB = CD
CD = 7 so....
x = 7
AD = y + x
AD = BC
BC = 18 so...
y + x = 18
y + 7 = 18 subtract 7 from 18
y = 11
Answer:
the answer is (21, 6); 21 two-point shots and 6 three-point shots
Step-by-step explanation:
Separate the variables that you know, 6+8+4=18. Now look at your answer, we know that 18 is higher than 15, so one of the variables x, y, or z has to be a zero. 6+8=14 or 6+4=10, so the 8(y)=0 and y=0. Now the 6 has to have the y=1 and the 4 and be multiplied by 2 or 1. Whit this there are only three answers, the first three. If 6(1)+4(1)=10 then x+y+z≤12 could be our answer. If 6(1)+4(2)=14 then we are left with 2 answers, 3x+y+z≤15 or x+2y+z=15. When you only need one answer you will go with x+y+z≤12
