Answer:
Step-by-step explanation:
Paperback Books:
Number of books
Cost of 1 book
Magazines:
Number of magazines
Cost of 1 magazine=
If you were at 54 on the number line you would have to cross zero and go an extra 13 steps to get to -13.
So we want the difference between 54 and -13 or 54- -13 which becomes 54+13 which is 67 - that is the range
Answer:
Weight on 1 may = 104 lb
Step-by-step explanation:
Given:
Weight on last may = 110 lb
Weight gain for to week = 2 x 19 = 38 lb
Weight lose for to week = 2 x 22 = 44 lb
Find:
Weight on 1 may
Computation:
Weight on 1 may = Weight on last may - Weight gain for to week + Weight lose for to week
Weight on 1 may = 110 - 44 + 38
Weight on 1 may = 104 lb
Answer:
infinitely many
Step-by-step explanation:
Add 12-y to both sides of the second equation to put it into standard form like the first equation:
y +(12 -y) = (x -12) +(12 -y)
12 = x - y . . . simplify
x - y = 12 . . . . second equation in standard form
We see this is identical to the first equation. That means every solution of the first equation is also a solution of the second equation. There are infinitely many solutions.
