Answer:
it is x=27.if im wrong im sorry im 10 and in collage. im smart but i have a lot of work to do.
Step-by-step explanation:I have a lot of thinges on my mind.
determine the mode for the following set of test scores: 63, 70, 75, 80, 85, 85, 85, 92, 92, 95, 99. (a.92) (b.85) (c.84) (d.83)

The mode is the score that occurs the most
Here it is 85
Choice B
A common logarithmic provides the following value for the log10 of 8.65:
<span><span>0.9370161
Which number is closest to this one?
The answer is D) 0.9370.
This means that 8.65 = 10^(.9370). Note that that the number is less than 1, since 10^1 is 10, and 8.65 is less than 10. </span></span>
Two ratios that are equal to 7:6 are 14:12 and 21:18, as they are the same, but 7 and 6 are multiplied by the same number (2 in the first, and 3 in the second.)
Use the arithmetic operations to get the variable x on one side of the equation and everything else on the opposite side.
If something is being is being done to a variable, we undo that operation by using the inverse of that operation.
For example, if 10 is being added to x, we use the inverse of addition or subtraction.
18 - 7x = -20.5
We variable x is being multiplied by 7 and is subtracting 18. We need to undo all those operations.
18 - 7x = -20.5
-7x = -38.5
Now the variable is only being multiplied by -7. Reverse the operation.
-7x = -38.5
x = 5.5
So, x is equal to 5.5.
