22×2= 44 (for the pants)
92-44= 48 (total for shirts)
48÷4 (total number of shirts)= 12 per shirt
3/12 is simplest form, it can't go lower.
8a² - 4b + 7a² and 5(3a² - 2b) + 6
First, simplify the expressions.
1) 8a² - 4b + 7a²
Add like terms.
15a² - 4b
2) 5(3a² - 2b) + 6
Distribute 5 by multiplying the number to each terms inside the parenthesis.
15a² - 10b + 6
15a² - 4b ≠ 15a² - 10b + 6
Solution: The expressions are not equivalent.
An angle bisector is one that cuts an angle into two equal halves.
bearing in mind that a degree has 60 minutes and a minute has 60 seconds, so then 171°30' is just 171 degrees and 30 minutes.
let's halve each, 171 ÷ 2 = 85.5°, so 85.5° is really 85° and half of another degree, let's recall that a degree has 60 minutes, so half of a degree is just half of 60 minutes, namely 30 minutes, so 85.5° is really 85°30'.
let's halve the 30 minutes now, half of 30 is 15, so 15 minutes is its half.
now let's add both halves together, 85°30' plus 15', 85°45'.
