4(x+2) = 4·x + 4·2 = 4x + 8
3(x+7) = 3·x + 3·7 = 3x + 21
5(2x+7) = 5·2x + 5·7 = 10x + 35
Answer:
66.667%
Step-by-step explanation:
In a fair die, there are 6 possible rolls. Out of the 6, 1 number is chosen each time. Since order does not matter in this problem, we will be applying combination, so this would be written as 6C1 x 4. In order to exclude 3 and 4, from 6, the choices must be narrowed down to 4. Written out as an equation, this would be 4C1 x 4. To get the percentage, simply divide the two equations.
(4C1 x 4)/(6C1 x 4) = 0.66667 = 66.667%

Answer:
22-6x>4
One solution was found :
x < 3
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
22-6*x-(4)>0
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
18 - 6x = -6 • (x - 3)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by -6
Remember to flip the inequality sign:
Solve Basic Inequality :
2.2 Add 3 to both sides
x < 3
