Answer:
A) B. 18-6
B) 20÷4
C) 20
Step-by-step explanation:
<u>Part A</u>
The order of operations tells you that the first step is to evaluate any expressions in parentheses. Here, that means you first evaluate (18 -6).
__
<u>Part B</u>
After parentheses have been removed, the next step is to perform multiplication and division. Here, there is only one term involving division, so you divide 20 by 4 as your second step.
__
<u>Part C</u>
After you have done parts A and B, your expression is ...
3 + 12 + 5
The value of this sum is 20.
Answer:
6 cases
Step-by-step explanation:
76÷14= 5.4
round up so every item can be put in a case.
Inequality: 120m>=2w+2(6+w). (6+w=l). this is it because you cant have a bigger perimeter than what you need. distribute: 120m >=4w+12. subtract 12 from both sides, then divide by 4. that will give you w=27. add 6 and get 33 for length
Answer:
x = 17.5°
Step-by-step explanation:
complementary means their sum is 90°.
