Answer:
x (children) = 58
y (students) = 66
z (adults) = 29
Step-by-step explanation:
Step 1: Write system of equations
x + y + z = 153
5x + 7y + 12z = 1100
1/2x = z
The best way to solve the systems of equations is to use an augmented matrix:
Top row: [1 1 1 | 153]
Middle row: [5 7 12 | 1100]
Bottom row: [1/2 0 -1 | 0]
And then put it in RREF form:
Top row: [1 0 0 | 58]
Middle row: [0 1 0 | 66]
Bottom row: [0 0 1 | 29]
Yes.
y represents the temperature.
x represents the number of hours past 8:00am.

Answer:
3 and 1
Step-by-step explanation:
the sequence is dividing each # by 2
Answer:
you will eliminate the y variable
Step-by-step explanation:
perpendicular lines are negative reciprocals of each other so if line p has a slope of 2 then line q has a slope of -1/2.
