90 x= 81 + 25 I need help ?

charle [14.2K]

Answer:

$x = \frac {53} {45}$

Step-by-step explanation:

Step 1: Combine on the right side

$90x = 81 + 25$

$90x = 106$

Step 2: Divide both sides by 90

$\frac {90x} {90} = \frac {106} {90}$

$x = \frac {106/2} {90/2}$

$x = \frac {53} {45}$

Answer: $x = \frac {53} {45}$

zubka84 [21]

Substituting x = 3 into the first expression:

-4(3) - 8 = -12 - 8 = -20

Substituting x = 3 into the second expression:

-2(3 + 1) - 2(3 + 3) = -2(4) - 2(6) = -8 - 12 = -20

egoroff_w [7]

Answer:

126

Step-by-step explanation:

In this case n = 9 and r = 4

9!/ (4! * (9-4)!)

9!/ (4! * 5!)

= 126

9! = 9x8x7x6x5x4x3x2x1
