Mr Tanaka used 10 gallons of gas. You find this answer by diving the denominator (3) with the total number of gallons of gas. So 15 divided by 3 is 5. Now you get the number 5, and multiply it by the numerator (2). 5*2 is 10. That is how you find the answer.
1) A
the lowest number is -3 and as it goes on, the number gets bigger and bigger therefore x must be larger than -4 but <u>not</u> equal to it.
2) D
the largest number is 9 and as it goes on, the number gets smaller therefore x must equal to and less than 9.
3) D
the largest number is 0 and the arrows points towards the negative numbers and the solid dot tells us that x can be equal to the number therefore the x must be equal to or less than 0.
4) A
the smallest number is -6 and the arrow points towards the positive numbers and the open dot tells us that x does not equal that number therefore x must be greater than -6 but <u>not</u> equal to it.
So 50 per week+3 times number of sales
represent s as number of sales
pay=50+3s
if you want pay to be at least 110 or pay<u><</u>110 so
110<u>></u>pay=50+3s
110<u>></u>50+3s
treat as regular equation: do the saem to both sides so it will stay equal
also isolate the s term
110<u>></u>50+3s
subtract 50 from both sides
60<u>></u>3s
divide both sides by 3
20<u>></u>s
you must make at least 20 sales
