If a+b=5 and a-b=3 then b=? a) -2 b) 1 c) 2 d) 4 e) 8 i think the answer is 1?

a+b=5 and a-b=3 should be re-written as

a+b=5

a-b=3

Combine these to obtain 2a = 8. Then a =4. Sub 4 for a in either equation. If you do that in the 2nd equation you'll get 4 - b = 3, or b = 1.

Then the solution is (4,1). Please note that this has 2 parts: 4 and 1.

These are the coordinates of the solution, the point at which the 2 lines intersect.

answer for #1 is c

answer for #2 is d

can i get brainliest

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
