Answer:
(c) 41 gallons
Step-by-step explanation:
Since each interval has a width of 1, you can simply add the numbers at the right end of intervals 1–5: 6 + 6 + 8 + 9 + 12 = 41
An estimated 41 gallons of water flowed in the first 5 minutes.
Answer:
D. (-14)+(-8)
Step-by-step explanation
Adding to negatives is the same as subtracting 2 positives
-14- 8= 22
-14+(-8)= 22
Answer:
the first one to solve for x is x=22-y
the first one to solve for y is y=22-x
the second one to solve for x is x=6+y
the second one to solve for y is y=-6+x
Step-by-step explanation:
in the first two you had to subtract y from both sides of the equation
the second one you had to add y to both sides of the equation to solve for x
but to solve for y you have to move all terms that dont contain y to the right side and solve
