Eva is working two summer jobs, making $16 per hour tutoring and $8 per hour clearing tables. Last week Eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Graphically solve a system of equations in order to determine the number of hours Eva worked tutoring last week, x,x, and the number of hours Eva worked clearing tables last week, yy.
Answer:
48 and 32 6 hours clearing tables and 2 hours tutoring
Step-by-step explanation:
we can rewrite this as a fraction. we will use 1/10s because 80 can be divided by 8 which is in the problem. we then have to find out what two numbers add up to 8 but one is 3 times the other. 6 and 2 fit into this problem so we plug it into the equation and we write it as this 6x+4x=80 where x is 8. we get 48 and 32.

Answer:
Yes, it can, because -4.5 lies to the left of -3.5
Step-by-step explanation:
we know that
The solution of the inequality is equal to the interval------> (-∞,-3.5)
All real numbers less than -3.5
x<-3.5
Substitute in the inequality
-4.5<-3.5 ------> is true
therefore
The number -4.5 is a value in the shaded region, because lies to the left of -3.5

as percentages
Answer:
Step-by-step explanation:
5/6= 83.33%
9/11= 81.81%
1 3/7= 142.85%
Answer:
(x) 83.(3)%
(xi) 81.(81)%
(xii) 142.(857142)%
Step-by-step explanation:
The thing to do is perform the division and write it as percentages.
Please note that all 3 of those are infinite fractions, so
83.(3) means 83.33333333333333333...
81.(81) means 81.8181818181818181...
142.(857142) means 142.857142857142857142857142857142...
If you wanted to round to nearest % or something, you can do that.
Eg. rounding to 2 places after the period:
83.(3)% ~= 83.33%
81.(81)% ~= 81.82%
142.(857142)% ~= 142.86%
