So average=(total of scores)/(number of tests)
needs at least average of 70
at least is represented as greater than or equal to or the sign (<u>></u>)
70<u>></u>(total)/(number oftests)
since we have 3 tests, we have to have 3 scores so
70<u>></u>(x+y+z)/3
he scored 85 and 60
70<u>></u>(x+85+60)/3 (doesn't matter which to subsitute)
70<u>></u>(x+145)/3
multiply obht sides by 3
210<u>></u>x+145
subtract 145 from both sides
65<u>></u>x
he needs to get at leas 65 on his third test

To find the lowest form of a fraction or simplifying you find a number that divide into the numerator(Top Number) and denominator(Bottom Number)
For example
4(Numerator)
_
16(Denominator
Both numbers can be divided by 4
4/4= 1
_ _
16/4=4
A way to check if your right is to divide both fractions you should get the same answer
4/16=0.25
1/4=0.25
