Hello!
The sum of 5/6 and 1/2 is 1 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 + 1/2 = 1 1/2
The difference of 5/6 and 1/2 is 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 - 1/2 = 1/2
Hope this helps!

Answer:
An Acute Angle
Step-by-step explanation:
Start by combining LIKE-TERMS. 13b AND 23 are LIKE-TERMS because they have the same variable (B) and numbers. Remember PEMDAS OR Please Excuse My Dear Aunt Sally. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). There is also FOIL (First, Inside, Outside, Last). Because we will start with Parenthesis(Use the FOIL method because the 56 is part of the parentheses) first, (-56 x b[first part of the set]) = -56b THEN (-56 x [+ {always carry the sign, this shows that it is positive}]1) = -56
Now we have 13b+23b -56b-56
=36b -56b -56
= -20b - 56
This is your final equation because THESE ARE NOT LIKE-TERMS, therefore, they CANNOT be combined
X+3≤ -5+2x
Add 5 to the other side. (the inverse of subtraction, since 5 is negative)
x+8≤2x
Subtract x on both sides.
8≤x <- the answer
I hope this helps!
