Find three consecutive odd integers such that the sum of the largest and twice the smallest is 25. If x represents the smallest integer, then which equation could be used to solve the problem?

Friday, July 16th, 2010

Solution:

X is the smallest number

y=x+2

z=x+4

z+2x=25

x+4+2x=25

3x=21

X=7

Y=9

Z=11

The equation that we used to solve the problem is x+4+2x=25, which can be simplified to = x=21.

If a line passes through the points (3, 5) and (1, 2), its slope is =______.

The slope is defined as the change in Y divided by the change in X.

In this case, this would equal
(5-2)/(3-1)
= 3/2
= 1.5
