4h+3=The Pay of Shea
3.5h +6= The pay of Kelly
4h+3=3.5h+6
-3 -3
4h=3.5h+3
-3.5h
.5h=3
*2 *2
h=?
Then stick "h" into one of the original equations and solve for someones pay to get "p"
3.5(h)+6=p OR 4(h)+3 =p
To solve this, you would set up the equation to find the arithmetic mean of the data. This equation is (53+83+67+73+x)/5=70, where x=the score of the fifth exam. First, you combine the constants to get (276+x)/5=70. Then, multiply both sides by 5 to get rid of the denominator, to give you 276+x=350. Then subtract 276 from each side to get x=74. So, Thanh needs to score a 74 on his last exam to get a 70 in the class.
