Answer:14
Step-by-step explanation:
Answer:
x>-2
Step-by-step explanation:
because it is divided by -4.
Answer:
x=-1
Step-by-step explanation:
54x+64=49x+59
subtract 64
54x=49x-5
subtract 49x
5x=-5
divide by 5
x=-1
X=number of adults, y= number of students
x+y=12
18x+12y=162
You can simplify the second equation by dividing by six: 3x+2y=27
Rearrange the first equation: y= 12-x. Plug y into the simplified second equation:
3x+2(12-x)=27
3x-2x+24=27
x=3.
Plug the now known x value into y=12-x. So y= 9.
Therefore, there are 3 adults and 9 students.

Answer:</h2>
The first consecutive odd number is: 9
and the second consecutive odd number is: 11
<h2>
Step-by-step explanation:</h2>
Let the two consecutive odd numbers be: a and a+2
( Since, we know that the difference between two consecutive odd or two consecutive even numbers is always 2 )
Now, it is given that:
Three times the first is 5 more than twice the second.
i.e.

Hence, we get:
The first consecutive odd number is: 9
and the second consecutive odd number is: 9+2=11
