Answer:
sin(x)-cos(x)
Step-by-step explanation:

Simplify the denominator:

Simplify the numerator:

Divide the fractions: <u>(a/b)/(c/d) = (a * d)/(b * c)</u>:

Use the identity: <u>2cos(x)sin(x) = sin(2x):</u>

Cancel out the common factor (sin(2x)):
-cos(x) + sin(x)
Simplify:
sin(x) - cos(x)
The sum of 3 fifteens and 4 twos will be 45 +8 = 53
Answer:
-2.5 = x
Step-by-step explanation:
-10 = 4x
the equation between 4 and x is multiplication
as our goal is to move the x on its separate side, we should divide each side by 4 to get rid of the bond between the 4 and the x
Therefore,
-10 = 4x
-10/4 = x
Simplify into decimal if needed
-2.5 = x

Answer:
Step-by-step explanation:
to turn a decimal to a percent, multiply by 100.....or if there is a decimal in there, start from the decimal and just move 2 spaces to the right.
2.346 = 234.6%
and just so you know, to turn a percent to a decimal, divide by 100...or move the decimal point 2 spaces to the left
