-3 to both sides
4b/2 = 8 +b

multiply both sides by two
(4b/2 = 8 + b) X2 = 4b = 16+2b

subtract 2b from both sides
2b = 16

divide both sides by 2
b=8

How to solve an equation.

1. Simplify any parentheses using the distributive property if needed.
2. Combine like terms if needed.
3. Use the addition principle of equality if needed.
4. Use the multiplication or division principle of equality if needed.

$\frac{4b}{2} + 3 = 11 + b$
2b + 3 = 11 + b
b + 3 = 11 <-- Subtract b from each side
b = 8 <-- Subtract 3 from each side

So, b is equal to 8.

Let's solve your equation step-by-step.0.2(x+50)−6=0.4(3x+20)Step 1: Simplify both sides of the equation.0.2(x+50)−6=0.4(3x+20)(0.2)(x)+(0.2)(50)+−6=(0.4)(3x)+(0.4)(20)(Distribute)0.2x+10+−6=1.2x+8(0.2x)+(10+−6)=1.2x+8(Combine Like Terms)0.2x+4=1.2x+80.2x+4=1.2x+8Step 2: Subtract 1.2x from both sides.0.2x+4−1.2x=1.2x+8−1.2x−1x+4=8Step 3: Subtract 4 from both sides.−1x+4−4=8−4−1x=4Step 4: Divide both sides by -1.−1x−1=4−1x=−4Answer:x=−4

Answer:

7.92% probability that a particular death is due to a traffic accident

Step-by-step explanation:

The relative frequency approach to find the probability that a particular death is due to a traffic accident is the number of deaths due to traffic accidents divided by the total number of deaths.

We have that:

624 deaths from traffic accidents

7883 total deaths.

$p = \frac{624}{7883} = 0.0792$

7.92% probability that a particular death is due to a traffic accident
