State a conclusion that seems reasonable. 6 + 0 = 6, 8 + 0 = 8, 9 + 0 = 9, 100 + 0 = 100.

Whatever number added to 0 remains the same.

Step-by-step explanation:

When you add a number to 0, the number itself doesn't change at all because there isn't anything in 0. So any number that is added to 0 doesn't change at all.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
