HELP PLEASE!!!!!!! This is due tomorrow. 20 points for this.
gogolik [260]

Answer:

x=16.75 y=4.5

Step-by-step explanation:

first turn the first trapezoid sideways so the side that says 8 matches with the side that says 10. This is the proportion. 8:10. The bottom of the first trapezoid says x+2. This matches with the side that says 15. Because the side that says 15 is on the bigger trapezoid, multiply by ten. Then multiply the other trapezoid by 8. We get an equation that looks like. 8x+16=150 Simplify and 8x=134 divide and we get x=16.75. Do the same for the side with y. 8y-24=50. 8y=36 y=4.5. There you have it.

Kim mowed 1/4 of her yard. Her son mowed 3/7 of it. Who mowed the most. How much is left
Pepsi [2]

Answer:

A. Kim's son

B. 9/28

Step-by-step explanation:

Give the fractions a common denominator of 28 then add.

12/28>7/28, so the son mowed more. 7/28+12/28=19/28. subtract this from 1 whole lawn and get 9/28.
