Nathaniel is working two summer jobs, making $20 per hour tutoring and making $10 per hour clearing tables. In a given week, he can work at most 13 total hours and must earn no less than $160. If x x represents the number of hours tutoring and y y represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
