I would love to mark brainliest! ;)

113 people

Step-by-step explanation:

5 stacks of 45 pounds is 225 pounds.

If each person eats 2 pounds, then you need 112.5 people. 225/2=112.5 but you cannot have half a person. So your answer is 113

if x decreases by 4 then y increases by 10

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
