Answer:
B
Step-by-step explanation:
Our system of equations is:
3x + y = 23
8x + 2y = 23
If we want to use substitution, that means that we essentially want to manipulate one of the two equations so that one variable (like y) is written in terms of the other (like x), and then substitute that expression into the second equation so that we have one variable and one equation and we can easily solve from there.
So the first thing to be done is to write one of the variables in terms of the other. It would be easiest to do it with the first equation and write y in terms of x - in other words, "solve the first equation for y".
The answer is B.
Answer:
The part AP to the whole AB ratio is 1:5
The part BP to the whole BA ratio is 4:5
Step-by-step explanation:
The given information are;
The number of parts in AB = 5 parts
The number of parts in AP = 1 part
The ratio of the part AP to the whole part AB is given as follows;
The ratio of AP to AP = The ratio of 1 part (AP) to 5 parts (AB)
Therefore;
The ratio of AP to AB = 1:5
The part AP to the whole AB ratio = 1:5, similarly, we have;
The ratio of BP to BA = The ratio of 5 part (BP) to 5 parts (BA)
Therefore;
The ratio of BP to BA = 4:5
The part BP to the whole BA ratio = 4:5.
