Statements 2, 3, and 5 are true based on the graph of this function.
Answer:
1) The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.
2) The solution x=60 represents the total food bill.
These both answers are correct.
Step-by-step explanation:
Since there are 8 group of friends, and the total amount spent by them is $76 including the tip i.e $16.
If x is the food bill our equation can be:
(x+16)/8 = 76/8
Solving the equation
(x+16)/8 = 9.5
x+16= 9.5*8
x= 76 -16
x= 60
The food bill is x=60.
6x-9=15
6x=24
x=4
Therefore the answer is A.

Answer:
All are 63
Step-by-step explanation:
m∠1 = 180 - 117 = 63 (linear pair)
m∠2 = 63 (alternate interior angle with ∠1)
m∠3 = m∠1 = 63 (isosceles triangle property)

Answer:the two equations that model the situation are
x + y = 48
3x + 2y = 15
Step-by-step explanation:
Let x represent the total number of hours that Derek worked.
Let y represent the total number of hours that Donnie worked.
Derek and Donnie mow 15 lawns over two 2 days. There are 24 hours in a day. Therefore, the number of hours in 2 days would be 2 × 24 = 48 hours. Therefore
x + y = 48 - - - - - - - - - -1
If Derek mows 3 lawns per hour and Donnie mows 2 lawns per hour, it means that
3x + 2y = 15 - - - - - - - - - 2
