Answer: x = - 19
y = 55
Step-by-step explanation:
y = - 3x - 2 (1)
5x + 2y = 15 (2)
substitute y = - 3x - 2 into equation (2)
equation (2) becomes
5x + 2 (-3x - 2) = 15
5x + ( - 6x - 4) = 15
opening the bracket
5x - 6x - 4 = 15
collecting like terms
5x - 6x = 15 + 4
-x = 19
x = - 19
substituting x = - 19 into equation 1
y = - 3x - 2
y = - 3 (-19) - 2
y = 57- 2
y = 55
The commutative propertyof addition says, "that you will get the same answer whether you are adding 1+2 or 2+1. this also works for 2 or more number."
I hope this helps!
Answer:
The answer is 1000 1000
Step-by-step explanation:
In HEX, it would be 88.
In DEC, it would be 136.
In Oct, it would be 210.
Binary, how to add numbers together.
1101101
+ 11011
10001000
This is just like adding regular numbers together.
For example, when you add 88 to 55, this is what will happen
1(r)
88
+ 55
13(+1) 3
143
With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.
