ok I've got an entire sheet of problems like the following where I must fill in the missing digit:

7 x 4 - A = 25 <---------- this is easy but the ones like this get to me,

5 x C x 33 + 42 = 6,642

91 (divided by) A + 25 = 38

Yeah, im in 8th grade and these are just reviews from other years and I COMPLETLEY forgot them :oops: .

And if I posted this in the wrong place sorry.
 
What's your question? I see no "missing digit" and the likes :shock:
 
5 x C x 33 + 42 = 6,642

C = missing digit.

I replaced the missing digits with letters for the sake of making things look a little neater.

Use * for multiplication, not x : 5 * C * 33 + 42 = 65
WHY are you calling it a digit? It's a NUMBER!

5 * C * 33 = 165C; so 165C + 42 = 6642
Can you solve that for C?
 
Ok I think Im confused I dont have to SIMPLIFY I have to find what the value of C is so...
 
1) Change your signature. You have no chance of success with an attitude like that. It isn't funny.

2) "Simplfy" is a very odd term. Solving very often is simplfying. Can you solve that last expression for C, or not?

3) Try to relax.

Try solving the equation one of the tutors provided to you earlier.

Thank you.

Hey

Hey I'm here to help so your solving for C....yes?

1.So first simplify your promblems(combine like terms)
2.Now that you've done that do the Order of Operations

P = Parenthesis = Please
E = Exponents = Excuse
M = Multiplication = My
D = Division = Dear
A = Addition = Aunt
S = Subtraction = Sally

3. Ok now that you know what they are try solving (the second eqauls sign is how to remember them)

4. So what did you get? If you got an answer and understand try plugging the vaule of "C" back into the problem and check.....my teacher calls this "Plug n' Chug"

YOU SHOULD GET AN ANSWER AND SEE IF YOUR RIGHT

If you don't.....

1.Check your work on the checking
2. Try Checking your work that you did originally
3. Ask Questions, and reply back to this topic and I help you some more

p.s. Private Message (PM) if you need more help I would be happy to help you! :)
 
Oh ok now I get it, Thanks for the help

5*C*33+42 = 165C + 42 = 6,642 Which means...... 165 * what + 42 = 6642 :idea:
