The answer is 3 equation is 3x-3=2x
The first statement says that the number tripled is 3 more then when it’s doubled. It means that 2x which is being doubled is equal to 3x-3.
You set it up as 3x-3=2x
To solve you subtract the 2x from both side and end up with x-3=0
And then you have to add 3 to both side to get the answer x=3

Answer:

-cos^4(x)

Step-by-step explanation:

Step 1: Use the Pythagorean identity : 1=cos^2(x) + sin^2(x)

1-sin^2(x) = cos^2(x)

-1+sin^2(x) = -cos^2(x)

cos^2(x) (-cos^2(x))

Step 2: Factor out common terms cos^2(x)

cos^2(x) (sin^2(x)-1)

Ans: -cos^4(x)

Answer:

75%

Step-by-step explanation:

we know that 60% of x is 120. we can rewrite this to .6x = 120, to get x we divide both sides by .6, so x = 200. now 120 + 30 = 150. then we divide 150 out of 200 which is .75 it 75%
