Equation 1: x + y = 40 ; therefore y = 40 - x
Equation 2: 25x + 15y = 900
Find x first:
25x + 15 (40 - x) = 900
25x + 600 - 15x = 900
10x = 900 - 600
x = 300÷10
x = 30 hours Chris needs to spend for tutoring job
y = 40 - 30
y = 10 hours Chris needs to spend for referencing job
Answer:
True
Step-by-step explanation:
This is true. x + 25 equals 40 in both cases, so they're equal.
A. (x-2)(x+5)(x-3) is the correct answer to this question : )
Something is missing there is no given. But here are the given for this question:
Salary = $8.75 per hour
40 hour work week
52 work week per year
5 days of work per week
Gas mileage is 21 miles per gallon
Gas costs is 1.26 per gallon
Average speed is 45 miles per hour
Daily round trip to work and back home is 34 miles
a. Kevin’s annual salary is 8.75 per hour x 40 hour work week x 52 work week per year
= $18,200
b. Kevin will spend on fuel each week:
34 miles daily round trip x 5 day work week divided by 21 miles per gallon x 1.26 per gallon
= $10.20
c. Kevin will spend _ hours on commuting
= 34 miles is the daily round trip x 5 day work week divided by 45 miles average speed per hour
= 3.78 hours
Hope this helps!
