Answer:
14
Step-by-step explanation:
Percentage 42 / 1200 * 400
We have that
<span>1/4 x + 2/3 y = 5 ----> multiply by 12 both sides---> 3x+8y=60
1/2 x + 3/2 y = 11---> multiply by 2 both sides----> x+3y=22
therefore
the answer is the option
</span><span>B. 3x + 8y = 60 ; x + 3y = 22</span>
Y=40x+100 and the second question is y=1.69x
Yes, 790 is divisible by 2. The answer is 395
