Luka is shopping for t-shirts. The first t-shirt costs $18.00, and every t-shirt after the first costs $12.00. If Luka has $65.00 to spend on t-shirts, which of the following inequalities represents the number of t-shirts, t, that he can buy?

A. t≤4

B. t≥4

C. t≤3

D. t≥3

answer is D.

Step-by-step explanation:

If you add up 18 + 12+12+12, you get 66.

but he has 65, so it can't be A or B.

and it isn't C because 3 t-shirts cost less than the amount he has.

Thus, your answer is D.

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.
