When you write it as an inequality you get x + 19 ≈ 8.2 and when you solve it it should look like x + 19 ≈ 8.2
19 ≈ - <u>19
</u> x ≈ -10.8<u>

The answer is 3/9 or 1/3 chance of selecting a pair of white socks
2y+12 < 42
subtract 12 from both sides to isolate the 'y'
2y<30
since '2y' is multiplication, the opposite is division. divide by 2 to isolate the 'y'. doing so will flip the < sign to make it >.
y > 15

She makes $15 an hour. Her employers take out $125 weekly. She gets a paycheck for $205 that week.
Add the $125 back in that her employer took out and you can find how much she earned that week, it's $330. Divide $330 by $15 to find that she worked a minimum of 22 hours that week.
15h-125=205
15h=330
h=22
plug 22 in to the equation 15h-125=205 to check your answer

Answer:
45% decrease
Step-by-step explanation:
The formula for percent of decrease/ increase is
Original - change/ original
So 40 - 22 = 18
18/40 = 0.45
Turn 0.45 to percent by moving the decimal two spaces to the right
45%
You can check by multiplying the original number by the percentage. So,
40 x 0.45 = 18
Answer:

let the unknown number be 'b'
y = -4x + b
-6 = 4*0 + b
b = -6
