Problem
How many 50-pound bags can you fill with one cubic yard of topsoil?
Result
About 83.
Solution
This is a division problem. So, we're going to divide the weight of one cubic yard of topsoil by 50
4,128 ÷ 50 = 82.56
Rounding to the ones place, we get 83.
First,
|-13| represents the absolute value of the number 13. Absolute values cannot be negative. So |-13| cannot become -13, it would become 13.
So,
|-13| - |13| = -13 - 13 = 26 would become
|-13| - |13| = 13 - 13 = 0

Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).
Answer:
C
Step-by-step explanation:
to find the first 4 terms, substitute n = 1, 2, 3, 4 into the expression
n = 1 → 1(1 - 1) - 4 = 0 - 4 = - 4
n = 2 → 2(2 - 1) - 4 = 2 - 4 = - 2
n = 3 → 3(3 - 1) - 4 = 6 - 4 = 2
n = 4 → 4(4 - 1) - 4 = 12 - 4 = 8
the first four terms are - 4, - 2, 2, 8 → C
