Does any one know how to do 2r+4<8 it’s aggravating me

Step-by-step explanation:

2r+4<8

subtract 4 from both sides

2r<4

divide by two

no need to reverse the sign since you are not dividing by a negative number

r<2

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
