Answer:
The answer is 6.
Step-by-step explanation:
If there are 270 students going on the trip and there would be a teacher for every 45 students you would have to divide.
You would divide 270 ÷ 45 = 6.
(-y + 5a - 4) + (3y - a - 5) is simplified to 2y + 4a - 11
<u>Given</u>:
The given equations are and
We need to determine the pair of numbers that is a member to the system of equations.
<u>Pair of numbers:</u>
The pair of numbers can be determined by solving the system of equations.
Let us use the substitution method to solve the equations.
Substituting in the equation , we have;
Thus, the value of x is 1.
Substituting x = 1 in the equation , we get;
Thus, the value of y is 7.
Hence, the pair of numbers that is a member of both the equations are (1,7)
if y=367
then you need to figure out this:
367=5x+287
so remove 287 from 367
367-287=80
Then divide by 5
80/5=16
so, x=16
