3(25x^3-16)
Hope that is what you were looking for
Step-by-step explanation:
you should only make one equation:
75 + 45x = 30 + 55x
subtract the 30 frim both sides, then subtract 45x from both sides. you are left with:
45 = 10x
Divide by 10 and get:
4.5 = x
After 4.5 hours, the cost is equal for either worker.
Answer:
13.6 g/ml
Step-by-step explanation:
Density is found by mass divided by volume
The mass is 306.0 and the volume is 22.5 ml
density = 306.0/22.5 =13.6 g/ml
We have 3 sig figs which is correct
Using the Slope Equation
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
