George's cost per day is
... c = 30 + 0.18m
We want c < 55, so we can write
... 30 + 0.18m < 55 . . . . . your inequality
_____
Here is the solution to the inequality
... 0.18m < 25
... m < 25/0.18
... m < 138.9
George must drive less than 138.9 miles that day.
Answer:
0
Step-by-step explanation:
2/10 is 2/10 away from 0, 2/10 is 3/10 away from 1/2, and 2/10 is 8/10 away from 1
There are 60 Country CDs and 136 Rock CDs.
Rock and country CDs = 196
Country CD = x
Rock CD = x + 76
Country CD + Rock CD = 196
x + (x + 76) = 196
2x = 196 - 76
2x = 120
2x / 2 = 120 / 2
x = 60 * number of Country CD
Rock CD = x + 76 = 60 + 76 = 136
To check:
Country + Rock = 196
60 + 136 = 196
196 = 196
Based on the angles, we know this is a 45-45-90 triangle.
In this type of triangle, x and y will be equal. The formula for the sides is x * rad 2 = 8 .
8/ rad 2 = 5.66
Both X and Y are 5.66 units.
