The given equation is
To solve for x, we have to subtract 8 to both sides
Now we need to get rid of -9 from the left side, and for that we do division
Answer:
omg im still dont no
Step-by-step explanation:
sorry
Answer : 9
Step-by-step explanation:
The answer is 9 because a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.
2 1/3hrs→ $18.20
1 hr→ $7.80
5 1/4hrs→ $7.80x5 1/4= $40.95
Answer:
Step-by-step explanation:
y = 3x + 2
6x – 2y = 10
Ryan’s answer:
I solved by adding the equations. The solution is .
y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =
6x – 2y = 10 → 6 – 2y = 10
7 – 2y = 10
–2y = –3
y = -
Jesse’s answer:
I used matrices. The solution is .
Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.
