Answer:
C
Step-by-step explanation:
I typed it into a graphing calculator. You could also choose a point (I choose (4,0) ) then plug it into each equation In the answers until you get back the numbers of the point you choose to represent x and y. For example
w=37
2w+w+69= 180 knowing that all triangles add up to 180 form an equation
3w+69=180 combine like terms and subtract 69 from both sides
3w=111 divide by 3 from both sides
w=37
Eileen is able to save 13% of her allowance each month.
Dress: 93$ at 100-25%=75%
-> divide the marked down cost by the percentage to get the cost of a single percent and then multiply it with the markdown again to get the saved cost
93/75*25=93/3*1=31*1=31$
shoes 119$ at 100-15%=85%
119/85*15=119/17*3=7*3=21
add both savings together for the full sum: 31+21=52$
