92=1/2*23*height
92=12.5*height
920/125=height
7.36=height

So the tenth place is the x in this number 2.x
so rounding to the tenth 5.07
7>5 so round up to 10
5.10
so 13.00
5.10=3 pounds
try and divide by 3
1.7=1 pound
divide 13 by 1.7
13/1.7=7.6 pounds
3 thousands (the 4 is in the ten thousands place)
2 hundreds
1 tens
9 ones
the average can be calculated by adding the scores together and then dividing by the number of scores.
we can set up an equation:
let x = test score needed on next test
(72+72+80+x)/4 = 71
multiply both sides by 4
72+72+80+x = 284
add like terms
224+x=284
subtract 224 from both sides
x=60
she will need a 60 for her average to be 71
