The correct answer according to me is 3=12
Answer:
Ok, so we have the fact that plus +minus=minus
Thats the fact. It always works that way that same signs means positive and different means negative, as explained with logic.
4+(-5)
So we know that 4 is positive and -5 is negative
if you look at it through a number line, substracting 5 from 4 you have
3--->2---->1---->0---->-1
Under zero, the negatives start, so its proved by maths and logic as well.
Step-by-step explanation:
X+x+2+x+2+2x-5=49
you would then combine all the x’s
which would equal 5x+2+2-5=49
the you would add up your numbers =ing
5x+-1=49
then add -1 to the other side of the = sign making the one positive which would equal
5x=50
divide by 5
x=10
Answer:
B
Step-by-step explanation:
521,370 would round to 521,400
26,839 would round to 27,800
