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]
Answer:im not really sure but i think log3(3) Logarithm base 3 of 3 is 1 .
Step-by-step explanation:
Answer:
2.2
Step-by-step explanation:
so you do it like this:
Since the fraction is 5/11 you take the demoniator which is 11 and you divide it by 5.
the answer would be 5236
476 x 1 would be 476. then 10 x 476 would 4760, add them together and you will get 5236
