Question

Phoebe wants to get atleast a grade of 90 in the math class. Her grade will be the average of two tests. She scored a 94 on the first test. write an inequality to represent the situation.

Answer 1

x≥86

Explanation:

to get at least a 90 she needs an 86, (86+94 or 180)÷2 so x has to be greater than or equal to 86 or x ≥ 86

Answer 2

First things first, you will have 94 + x. Place those on top of a fraction bar and on the bottom put the two numbers over 2. So you have 94 + x over 2. Then, write the symbol ‘greater than or equal to’ and on the other side place your 90. So, 90 + x over 2 is greater than or equal to 90. This is a difficult thing to write out and explain so I hope this makes sense. :)
