Hi there!
Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :
(x - 
) + 
= -7
subtract on each side of the equation
x - = -8.25
add on each side of the equation
x = -7.5
-7.5 - 3/4 = -8.25
-8.25 + 5/4 = <u>-7</u>
So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer: multiply the number of pounds by 16 to get number of ounces (since there isn't a number in between weighs/pounds)
Answer:
x=2.4650
Step-by-step explanation:
I assume that you mean 
so let s use the ln() function
so x = ln(15)/ln(3)
x = 2.4650
Answer:
where are the equations?
Step-by-step explanation:
tell me and I will edit my answer to answer ur question
To make the exponent positive, make a fraction. 1/3 * 1/3. This is 0.1 repeating. 3^1 is 3. So the answer is no.
