Answer:
x = 42
Step-by-step explanation:
y = x/7 + 15 ; y = 21
21 = x/7 + 15
21 - 15 = x/7
6 = x/7
x = 6 × 7
x = 42
Thus, The answer is 42

Answer:
43.94?
Step-by-step explanation:
I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.
cos(∅) = 
cos(∅) = 0.72
cos⁻¹(0.72) = 43.94
I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)
Simply divide $25,200 by 5

$5,400 was spent on housing
Planet A, because 7 x 10 > 5 x 10, the 28 is also bigger than 26. The numbers means 10 x 10 x 10 x 10... and so on to 28 or 26 (whatever the number is)
