since we know those two triangles are similar then we can use proportions.

$\cfrac{AE}{AB}=\cfrac{AD}{AC}\implies \cfrac{14-8}{2x}=\cfrac{14}{2x+4}\implies \cfrac{6}{2x}=\cfrac{14}{2x+4}\implies \cfrac{3}{x}=\cfrac{14}{2x+4} \\\\\\ 6x+12=14x\implies 12=8x\implies \cfrac{12}{8}=x\implies \cfrac{3}{2}=x \\\\[-0.35em] ~\dotfill\\\\ AB=2x+4\implies AB=2\left( \frac{3}{2} \right)+4\implies AB=3+4\implies AB=7$

7. Susan spent 30% of the money she earned mowing lawns last summer. If Susan spent $51, what was the total

KatRina [158]

Answer:

$170

Step-by-step explanation:

30% of the money was equal to 51

so:

$\frac{30}{100} = \frac{51}{x} \\ \\ x = \frac{5100}{30} = \frac{510}{3} = 170$
