Answer:
( -1,2)
Step-by-step explanation:
The solution is where the two lines intersect
The intersect at x=-1 and y=2
( -1,2)
You work 40 hours per week and make 13$ per hour, so multiply 40 and 13 and you get how much you make a week. Then find out what 10% of that number you got is and you get your answer.
You should get: 52$
Answer: 10
you have to find a common denominator between two and five which is 10. therefore making the number 2 into the fraction 20/10 and finding the common denominator of 1/5 makes it now 2/10. now divide 20 by 2 which gets you 10. and dividing 10 by 10 gets you. therefore making the new fraction 10/1 which is equal to 10. :)
-4 = x - 7
-4 + 7 = x
3 = x
Therefore x = 3
