Naomi, Macy, and Sebastián have 234 stamps in all. Naomi gives 16 stamps to Macy and 24 stamps to Sebastián. Naomi then has 3 times as many stamps as Macy, and Macy has twice as many stamps as Sebastián. How many stamps does Naomi have at first?

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
