Answer:
(-6,1)
Step-by-step explanation:
-2x+6y=18
-4x-6y=18
Add the two equations together to eliminate y
-2x+6y=18
-4x-6y=18
--------------
-6x = 36
Divide each side by -6
-6x/-6 = 36/-6
x = -6
Now we need to find y
-2x +6y = 18
-2(-6) +6y = 18
12 +6y = 18
Subtract 12 from each side
12-12 +6y = 18-12
6y = 6
Divide by 6 on each side
6y/6 = 6/6
y = 1
The inequality that shows no more than $450 is to be spent on frozen treats is 0.75C + 0.85I + 0.5F ≤ 450
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let C represent the number of chocolate fudge bars, F represent the number of frozen fruit bars and I represent the number of ice-cream sandwiches
Hence:
0.75C + 0.85I + 0.5F ≤ 450
The inequality that shows no more than $450 is to be spent on frozen treats is 0.75C + 0.85I + 0.5F ≤ 450
