Options C and D as there is already a relationship between the numbers 1 and 2.
Answer:
19
Step-by-step explanation:
KM=4
KN=9
9-4=5
MN=5
NL=14
5+14=19
Answer:
13
Step-by-step explanation:
9 + 2 x (3 - 1)
PEMDAS says parentheses first
9 + 2 x (2)
Then we multiply and divide
9+4
Then add and subtract
13
We can easily eliminate x. To do this, mult. the 1st eqn by -1: -x + y = 3
and add this result to the second equation:
-x + y = 3
<span>x + 3y = 5
</span>--------------
4y = 8 Then y = 2. Sub 2 for y in the 2nd equation: x + 3(-2) = 5
x = 5+6
Then x = 11
The solution is (11, 2).
Answer: y = -1x/5 -1
