X + 2x -20 = 85

Combine like terms:

3x -20 = 85

Add 20 to both sides:

3x = 105

Divide both sides by 3

X = 35

x = 35

Step-by-step explanation:

x + 2x - 20 = 85 , that is

3x - 20 = 85 ( add 20 to both sides )

3x = 105 ( divide both sides by 3 )

x = 35

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
