Answer:
The price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75
Step-by-step explanation:
We can solve by means of a 2x2 equation system, assuming that the question is the price of each product
We have to:
"x" price of drinks
"and" price of the bag of popcorn
9 * x + 4 * y = 40.5
3 * x + 5 * y = 38.25 => x = (38.25 - 5 * y) / 3
replacing:
9 * (38.25 - 5 * y) / 3 + 4 * y = 40.5
114.75 - 15 * y + 4 * y = 40.5
-11 * y = 40.5 - 114.75
y = -74.25 / -11
y = 6.75
now for x:
x = (38.25 - 5 * 6.75) / 3
x = 1.5
So the price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75
Answer:
b=1
Step-by-step explanation:
-11+3(b+5)=7
-11+3b+15=7
-11+15+3b=7
4+3b=7
3b=7-4
3b=3
3b/3=3/3
b=1

Answer:
a. 5
Step-by-step explanation:
To find slope, subtract the y's.
5 - -5 is 10.
Put that on the top of a fraction.
Subtract the x's.
3 - 1 is 2, put that on the bottom of the fraction.
So the slope is 10/2. This simplifies to 5 (because 10÷2 is 5).
The slope is 5.
