So if her pay check is x she spends 0.25x on the dress and 0.125x on shoes. That’s 0.375 when added together. So 0.375x + 24=60 0.375x = 60-24 0.375x= 36 X=36/0.375 X=$96
We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.
180=(x+12)+100+x
We can remove the parentheses and combine x plus x to 2x.
