Answer:
and 
Step-by-step explanation:
First, we are told "sum of 5 times one number, x, and 4 times a second number, y, is 75":
(1)
Then, we are told "he sum of the two numbers is 18":
(2)
At this point we have our system of equations and now we are able to find the values of 
and 
.
So, let's begin by isolating from (2):
(3)
Substituting (3) in (1):
(4)
Finding :
(5) This is the value of
Substituting (5) in (1):
(6)
Finding :
(7)
(8) This is the value of
Answer:
Cost of dinner: $10.85
Money to add: $1.40
Step-by-step explanation:
1. Calculate the cost of the chicken and broccoli: 3(3.15)+1(1.40)=$10.85

Answer:
-7 < -3 because -7 is located to the left of -3 on a number line.
Step-by-step explanation:
This is because -7 is on the left of the -3. In negatives -3 is greater than -7. If it was positive then 7 would be greater than 3. So the answer is A. -7 < -3 because -7 is located to the left of -3 on a number line
The y-intercept of the trend line is (0,28). The slope of this line is
28-0
m = --------- = 2
14-0
Thus, the equation of the trend line, in variables K and J, is
K = 2J + 28
124.5 minutes = 2 hours and 7 minutes and 5 seconds
