Answer:

b = 23/2 or b = 11.5

Step-by-step explanation:

STEP 1: Simplify both sides of the equation.

1/2(4b - 6) = 20

(1/2)(4b) + (1/2)(- 6) = 20 (DISTRIBUTE)

2b + - 3 = 20

2b - 3 = 20

STEP 2: Add 3 to both sides.

2b - 3 + 3 = 20 + 3

2b = 23

STEP 3: Divide both sides by 2.

2b/2 = 23/2

b = 23/2

To solve you move the variables to the side and divide both sides by the factor number that doesnt have the variables your answer would be b=23/2 as a decimal is 11.5

Answer:

sqrt(5)

Step-by-step explanation:

Honestly think this person means to find the magnitude of the vector. You can use dot product here, the vector with itself... But that isn't the last step.

v dot v=4+1=5

and so |v|=sqrt(5)
