0.2x+2.7x−8.1=6.9+1.1x

The answer is not x = 83 tho
and don't do it for the points

0.2x + 2.7x - 8.1 = 6.9 + 1.1x

Combine like terms on left side:

0.2x + 2.7x = 2.9x

Now you have:

2.9x -8.1 = 6.9 + 1.1x

Subtract 1.1x from both sides:

1.8x - 8.1 = 6.9

Add 8.1 to both sides:

1.8x = 15

Divide both sides by 1.8:

X = 8.3333 ( round as needed) or as a fraction = 8 and 1/3

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
