Answer:
16
Step-by-step explanation:
45 +25+25+10+10+19=134 so 150-135=16
The slope-intercept form: y = mx + b.
m - slope, b - y-intercept
We have the points (0, 75) → y-intercept (b = 75), and (7, 40).
Substitute the coordimates of the points to the formula of a slope:
<h3>Answer: y = -5x + 75.</h3>
Answer:
The number is 
Step-by-step explanation:
Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.
Our number is z, then the left hand side of the equation is 9z-4.
The right side of the equation is 122. Then the complete equation is 
. Add 4 in both sides to get 
. Now, divide by 9 in both sides to get 
Answer:she spent 10 hours working in her aunt's store last week.
Step-by-step explanation:
Let x represent the number of hours that Lee spent working at the movie theater.
Let y represent the number of hours that Lee spent working at her aunt's store.
Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that
x + y = 30
Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that
9x + 6y = 240 - - - - - - - - - -1
Substituting x = 30 - y into equation 1, it becomes
9(30 - y) + 6y = 240
270 - 9y + 6y = 240
- 9y + 6y = 240 - 270
- 3y = - 30
y = - 30/ - 3 = 10 hours
