The answer is 2. You gotta multiply them all together
Looking at the question, I'm assuming it has a mistake.
However, I will first attempt to solve it normally:
Simply combine like terms to get 5x = 180, and thus x = 36, and y = 72
The first mistake possibility is that the first equation should be <u>3x + 2y = 180</u>
If that is the case, simply substitute in 2x for y, turning the equation into
3x + 2 (2x) = 180
3x + 4x = 180
7x = 180
Thus, x = 25.715 and y = 51.43
Another possible mistake is that the first equation should be <u>3y + 2x</u><u> </u><u>= 180</u>
Solve similar to the first mistake
3 (2x) + 2x = 180
6x + 2x = 180
8x = 180
Thus, x = 22.5, and y = 45
Hope it helps :)

Answer:
D. Distributive proprety
Step-by-step explanation:
Because you have to distribute 2 to make it 2x and then do 2 (12) which is 24 and then add 2 to it again which equals 40
Answer:
176 grams of zinc.
Step-by-step explanation:
4/9 = x/396 where x = the number of grams of zinc.
Cross multiply:
9x = 4*396
x = 4*396/9
x = 176 grams.
