For this problem, all you would need to do is plug in numbers for x and y into the calculator. However, none of the ordered pair is a solution to the equations. Unless.. I made a mistake.
The answer is negative three
Answer:
choice 2) x+2y+3 = 7
Step-by-step explanation:
equation to match:
x+2y = 4
add 3 to each side
x+2y+3 = 7 (which is the same as choice 2, x+2y+3 = 7)
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation.
Hope this helps!
9 and 2/4 can be written as 9.5 in decimals. We usually round 5 up, so we would round it to 10.
if it was 9.4 we would round it down to 9.
