Answer:
Step-by-step explanation:
answer no 3:
1] Factor out the common term 2.
2(3x+y) = -26
2] Divide both sides by 2.
3x+y= -26/2
3x+y = − 13
3]Subtract y from both sides.
3x = - 13-y
4] Divide both sides by 3.
x = -13-y/3
Part 2:-
Add 6y to both sides.
x=21+6y
x=21+6y
The inequality which can be used to determine the number of gigabytes is 41.5 + 5x < 50 and the solution is x < 1.7
<h3>How to write and solve an equation which can be used to determine the number of gigabytes?</h3>
The given parameters are
Flat cost = $41.50
Rate = $5 per gigabyte
Budget = Under $50
The equation is represented as:
Total cost = Flat cost + Rate * Number of gigabyte
So, we have
y = 41.5 + 5x
The budget is under 50
So, we have
41.5 + 5x < 50
Subtract 41.5 from both sides
5x < 8.5
Divide by 5
x < 1.7
Hence. the inequality which can be used to determine the number of gigabytes is 41.5 + 5x < 50 and the solution is x < 1.7
