Bill should put the brackets around 18-9 so the correct answer is option B. 10- 4 +3 x (18-9)
Answer:
1/3
Step-by-step explanation:
Ask me in the comments of you need an explanation.
:)
P=2(l + b)
P=2l + 2b
P-2b=2l
P-2b/2=l
C is your answer
20: 30-4 x (2+5)=2
21. 17-(8-5)= 14
22. You put (10/2)-3+1, but it isn't necessary
Explanation: to solve these equations, use PEMDAS (parentheses, exponents, multiplication, division.) these equations don't involve exponents, though, so ignore that part. If 30 is left alone, you would multiply 4x2 before doing anything else. This would mean you would have 30-8+5' which gets you to 27, an incorrect answer. However, if you put parentheses around (2+5), you add those first, meaning you would then have 30-4(2+5) = 30-4(7) = 30-28= 2.

When solving an equation, we need to make sure that all variables are on one side and all numbers are on the other side.
Since we have numbers on both sides, we need to move all of them to one side:-
