Answer:
Step-by-step explanation:
-34 = (9/5)(-20) + b
b = -34 + 36 = 2
y = (9/5)x + 2
Answer:
-2(x)>30
An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
x<-15
Step-by-step explanation:
-2(x)>30 means to divide -2 on both sides which is -15.
x>-15
Next you switch the inequality because you multiplied by a negative:
x<-15
Set up the equation
320 = 80c
When solved for c, That is how many chairs she can buy,
Then add 3, for the three free chairs she gets
Well if you make $7.25 an hour and work four hours then multiply
7.25 x 4 = 29
so you make $29 a day and you work fro 5 days multiply the amount and the days which is
29 x 5 = 125
so you make $125 dollars after working 4 hours a day for 5 days
