Step-by-step explanation:
x = number of novels
y = number of dictionaries
x = 8y
88x + 208y = 13680
now, using the identity of the first equation in the second equation gives us
88(8y) + 208y = 13680
704y + 208y = 13680
912y = 13680
y = 13680/912 = 15
x = 8y = 8×15 = 120
so, there were 120 novels and 15 dictionaries sold.
Answer: y=2/3x-5
Explanation: The first thing I do is look for the y-intercept which is where the line goes through the y-axis, for this equation it's -5; then the slope the point goes up one and goes right 1.5, then put it into whole numbers so I'll times them by 2 so the slope is 2/3
With those you can put it into slope-intercept form: y=2/3x-5
Answer:
Commission is $45.00

She earned $195.00 for her paycheck
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
If you solve for x you get your answer. First, 20 - 10 gets you 10. Then you subtract that 10 from both sides of your equation so it now looks like 5x = 30. Last you divide both sides by 5 and get x = 6.
