Georgia lifts free weights. The bar weighs 25 pounds. She puts two 25 pound weights and two 10 pound weights on the bar. How much do the bar and the weights weigh altogether?

95 pounds

Step-by-step explanation:

25 from the bar

2 x 25 is 50 already plus the bar is 75

2 x 10 is 20 plus 75 is 95 pounds

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
