Answer: 2-(2x+40) or (2x+40)-2
Step-by-step explanation: If you wanted to solve the problem, you have to do the stuff in the parentheses before you do the stuff out of the parentheses. In the parentheses, you will have to solve 2x before you do anything else. When you solve 2x, the answer to that, add it to 40. Then the answer in the parentheses, subtract it by 2 and you can get the answer.
Answer:
i believe the answer is 3pi/4
Answer:
Options: A, B, and C correctly solve for x.
Step-by-step explanation:
A).
= 
Multiplying both sides by 2 gives;
5x = 15
x = 15 ÷ 5 = 3
∴ This option correctly solve for x.
B).
x +
= 7
x = 7 -
= 
∴ This option correctly solve for x.
C).
x + 3 = 
x = 
But the option give x as 5/6 hence this option does not correctly solve for x.
D).
5x = 11/2
x = 11/2 ÷ 5 = 11/2 × 1/5 = 11/10
But the option gives x as 10/11 so it does not correctly solve for x.
The answer to the question is 5 so CD=5
