Answer by JKismyhusbandbae:
x - 10 ≤ 19
x - 10 + 10 ≤ 19 + 10
x ≤ 29
x - 10 ≥ - 19
x - 10 + 10 ≥ - 19 + 10
x ≥ - 9
Answer: - 9 ≤ x ≤ 29
Using the problem, create an equation to find the number (x).
Three less than (so x minus 3) 6 times a number (6 times x) equals 39.
6x-3=39, solve for x.
x = 7
Answer:
Step-by-step explanation:
The better deal will be the one that costs the least per diaper. With this in mind, start by calculating the individual diaper cost for both deals.
—30 diapers for $4.25
$4.25/30
≈$0.14 per diaper
—125 diapers for $24.99
$24.99/125
≈$0.20 per diaper
Therefore, the deal with 30 diapers is the better buy.
