99/10 as a mixed fraction would be 9 9/10
40+0.45x=y
x=the number of minutes extra uses
y= total
40+0.45x=48.10
0.45x=48.10-40
0.45x=8.10
0.45/0.45=8.10/0.45
x=18
You can answer some questions that say (PLEASE ANSWER I WILL GIVE YOU BRAINIEST!!!!!!!) it usually happens if you answer it first ;D
Answer:

Step-by-step explanation:
Installation fee equation will be added onto the original equation
So g = base cost + percent cost + $100
(Cost of carpet) ---> g = $7.5x + ($7.5x * 0.05) + $100
Plug in 150 into the formula that gives you $1281.25
Make sure to study these, questions like these will for sure strengthen your math skills
Answer:
In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis.
