Solve the equation.

2(x + 5) = 3x + 1

x =

x=9

Step-by-step explanation:

1. expand brackets first

2(x + 5) = 3x + 1

2x +10=3x +1

2. subrtract2 x from both sides

2x +10=3x +1

10= x +1

3. subtract 1 from both sides

10= x + 1

9+x

x=9

Step-by-step explanation:

2(x+5) = 3x =1

2x + 10 = 3x + 1

10 = x + 1

9 = x

Step 1: Start out by using distributing property. You distribute the 2 to the x and the five, making 2x + 10.

Step 2: You put the variables on one side, keeping them positive. So you do the opposite of +2x, which is -2x. So you subtract 2x from 3x leaving you with 1x or x.

Step 3: You take the numbers and put them on one side, meaning you have to move the +1. TO do that, you do the opposite and take it away from the 10 leaving you with 9 = x

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
