The order to us solve is:
- Parentheses
- Multiplication
- Sum and subtraction
Let's go:
Therefore, the result is 62.2.
Answer:
This means that if you have that amount of those and you do whatever the rest of the question is.
Step-by-step explanation:
<span>We want to check how many intersections line A and B have, that is, we want to check how many common solutions do these equations have:
</span>
i) 2x + 2y = 8
ii) x + y = 4
<span>
use equation ii) to write y in terms of x as : y=4-x,
substitute y =4-x in equation i):
</span>2x + 2y = 8
2x + 2(4-x) = 8
<span>2x+8-2x=8
8=8
this is always true, which means the equations have infinitely many common solutions.
Answer: </span><span>There are infinitely many solutions.</span><span>

Answer:
6.6
Step-by-step explanation:
They are independent because they do not rely on each other.
