Answer:
Step-by-step explanation:
-x - y = -2
x - 2y = 2
-3y = 0
y = 0
x = 2
(2, 0)
Answer:
x = 1
y = 10
Step-by-step explanation:
5x + y = 15
Step 1: Move 5x on the other side by subtracting it from both sides
y = 15 - 5x
2x + y = 12
Step 2: Move 2x on the other side by subtracting it from both sides
y = 12 - 2x
Since y = y, that means 15 - 5x = 12 - 2x
Step 3: Add 5x to both sides
15 = 12 + 3x
Step 4: Subtract 12 from both sides
3 = 3x
Step 5: Divide both sides by 3
x = 1
y = 12 - 2x
Step 6: Plug in 1 for x
y = 12 - 2(1)
Step 7: Multiply 2 by 1
y = 12 - 2
Step 8: Subtract 2 from 12
y = 10
Answer:
the answer is 60, 60, 120, 120

Answer:
Plan C=12 weeks for 30 miles walked.
Step-by-step explanation:
This is a constant rate of change...the number of miles each week increased by 10 each time; the number of weeks was divided each time by 2. To find Plan C, divide 24/2, which is 12.
Hope this helps! Have a great day C:
