0.1d +.25 (10) = 12.5 what is d

d = 100

Step-by-step explanation:

0.1d + 0.25(10) = 12.5

0.1d + 2.5 = 12.5

0.1d + 2.5 - 2.5 = 12.5 - 2.5

0.1d = 10

0.1d × 10 = 10 × 10

d = 100

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.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
