Question 994474: What are all possible factors of a^6b^6?
Answer by MathLover1(11324) (Show Source):
Question 994245:
_4_
6+3(2)1=? The 4 goes over the 3(2) in fraction form..
_4_ _2_
I worked it and got to 6+ 6 1 = 6+ 3 1
The 4 goes over the +6 and the 2 goes over the +3 in fraction form. Not sure if you can see it like I typed it. I apologize.
But I can't figure out if I'm doing that right and where to go from there

Question 993951: What are the solutions of 4(3x5)+x<2y27 when y=4
Answer by Boreal(1464) (Show Source):
You can put this solution on YOUR website! 4(3x5)+x<2y27
y=4
12x+20+x<827
11x+20<35
11x<55;; divide by 11 and change the inequality
x>5
===
Check
4(10.01)+5<35
40.04+5 < 35
35.04<35
I used 10.01, but any number greater than 10 will work, If x=5, 10 would work.

Question 991134: 4x6+3x2+4
Create an equivalent expression that includes a set of parenthesis so that the value of the expression is 48
Found 2 solutions by Theo, solver91311: Answer by Theo(5548) (Show Source):
You can put this solution on YOUR website! you should use * to indicate multiplication rather than x.
this avoids confusion between a variable called x and the multiplication symbol.
your expression is 3*6 + 3*2 + 4
without parentheses this becomes 18 + 6 + 4 which is equal to 28.
place the parentheses as shown below and it will be equal to 48 as desired.
3 * (6 + 3*2 + 4)
the expression inside the parentheses becomes:
6 + 6 + 4 which becomes 12 + 4 which becomes 16.
3 * 16 = 48.
Answer by solver91311(20879) (Show Source):
You can put this solution on YOUR website!
Do not use "x" to indicate multiplication. Use "*" (Shift8). "x" gets confused with the variable x.
An "equivalent" expression is just that, equivalent. By the order of operations, your expression has a value of 34. Any equivalent expression, by definition must have a value of 34, otherwise it isn't equivalent.
And to add insult to injury, no possible configuration of A set of parentheses can transform the given expression into an expression that has a value of 48, presuming the order of numbers and operations must remain the same.

Change both fractions to a common denominator and then compare the numerators. You don't actually have to find the lowest common denominator.
10 times 9 is 90, so your first fraction converts to 27/90 and the second one converts to 20/90. 27 is larger than 20.

Question 989682: How do you solve this algebra equation?
9k + 6 = 8k + 13
Found 3 solutions by MathTherapy, ikleyn, josgarithmetic: Answer by MathTherapy(4047) (Show Source):
You can put this solution on YOUR website!
How do you solve this algebra equation?
9k + 6 = 8k + 13
Subtract 8k from both sides
Subtract 6 from both sides
This should give you the value for k, after combination of the liketerms on each side
Answer by ikleyn(988) (Show Source):
You can put this solution on YOUR website! .
Distract 8k from both sides.
You will get
k + 6 = 13.
Distract 6 from both sides. You will get
k = 13  6 = 7.
Answer. k = 7.

.(supply the step)
k=7
That can be done in one step or two steps.
That was the response. Use the properties.

My earlier "answer" of 19 was wrong. k=7 is the true answer. I did the steps in my head, and did not catch my mistake while handling these steps.

Ex) 5+(8×5)+72÷8. Answer for this is 8×5
1)5+9+10+16÷4
So what at I'm trying to figure out is what do I have to do please help me
Answer by stanbon(69061) (Show Source):
You can put this solution on YOUR website! Finding first expression
Determine the frist expression to evaluate
In each problem Ex) 5+(8×5)+72÷8. Answer for this is 8×5

Note: These are "order of operation" problems.
The proper order is PEMDAS which means parentheses,exponents,Multiplication,
Division,Addition,Subtraction.

1)5+9+10+16÷4
Ans: There are no parentheses
There are no exponents
There is no multiplication
There IS division, so the answer is 16/4
