Georgia Algebra 1 EOC Review Unit 2

A number of apples were shared evenly among 4 students. Each student was also given 2 pears. Each student received a total of 6 pieces of fruit. Let a represent the total number of apples. Which equation can be used to find the total number of apples?

• $\frac{a}{4}-2=6$

• $\frac{a}{4}+2=6$

• $4a+2=6$

• $4a-2=6$

A tour bus driver takes home 75% of the salary he earns and gives 60% of his tips to the tour guides on the bus. He took home $980 last week from salary and tips. Let s represent the diver's salary and t represent the total amount of tips the driver earns. Which equation can be used to find the possible amounts of his salary and tips the driver took home last week?

• $0.75s+0.4t=980$

• $0.75s-0.4t=980$

• $0.75s+0.04t=980$

• $0.75s-0.04t=980$

Ed and Greg are working on their math HW. Ed says (2,0) is a solution to y < 4x-8. Greg disagrees. Who is correct and why?

• Ed is correct because when he plugged (2,0) into the expression it resulted in a true statement, 0=0.

• Ed is correct because when he graphed the expression, (2,0) was on the boundary line so it is a solution.

• Greg is correct because when he plugged (2,0) into the expression it resulted in a false statement 0<0.

• Greg is correct because when he graphed the expression, (2,0) was not on the boundary line so it is not a solution.
