I'm not quite sure these are right. You might wanna check with a classmate or something first.
Step-by-step explanation:
(6x + 10) + (x + 17) + (4x - 34) = 180
11x - 7 = 180
11x = 173
x = 15.73 (answer had repeating decimal so i rounded up in the hundredths place)
(6x + 10)
6 (15.73) + 10
94.38 + 10
104.38
(x + 17)
(15.73) + 17
32.73
(4x - 34)
4(15.73) - 34
62.92 - 34
28.92
Step-by-step explanation:
Let n be the number of nickels that Casey has.
We are told that Megan has 4 times as many nickels as Casey has, therefore, the number of nickels that Megan has will be 4*n.
Now we will add the amounts of nickels that Casey and Megan have to find the total amount of nickels.
Therefore, the expression 
will represent the total number of nickels that Casey and Megan have .
Upon combining like terms we will get,
Therefore, Casey and Megan have 5n nickels.
42 degrees is the average.
A is the correct answer to this problem
Answer:
Answer in simplified mixed form is 1 5/6
Step-by-step explanation:
We need to solve: -6 7/8 divided by (-3 3/4)
This can be written as:
-6 7/8 ÷ (-3 3/4)
Since -6 7/8 = -55/8 and -3 3/4 = - 15/4
So we can write :
-6 7/8 ÷ (-3 3/4) = -55/8 ÷ (-15/4)
or (-55/8 ) / (-15/4)
or (-55/8) * (-4/15)
or -(-220/120)
or 11/6
or 1 5/6 , this is the answer
We got the answer in simplified mixed form is 1 5/6
