Find the equation and solve it.

1 answer:

5 0

4(3x + 1)= 76
*There are 4 sides to a square and they are all equal in length, so you would mulitply 3x +1 by 4
*The total perimeter is 76
*Distribute the 4 into the equation

12x + 4=76
*subtract 4 on both sides

12x=72
*divide 12 on both sides

x=6
*Plug 6 in for x in the equation

3(6) +1
*this means that each side of the square would be 19 meters
*If you want to check to make sure you solved for x correctly, just plug it into the equation[4(3x + 1)]

Hope this helps!

Suppose you have the following information. 12% of all drivers do not have a valid driver’s license, 6% of all drivers have no i

lubasha [3.4K]

Answer:

e) 0.14

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a driver does not have a valid driver's license.

B is the probability that a driver does not have insurance.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a driver does not have a valid driver's license but has insurance and $A \cap B$ is the probability that a driver does not have any of these things.

By the same logic, we have that:

$B = b + (A \cap B)$

We start finding these values from the intersection.

4% have neither

This means that $(A \cap B) = 0.04$

6% of all drivers have no insurance

This means that $B = 0.06$ . So

$B = b + (A \cap B)$

$0.06 = b + 0.04$

$b = 0.02$

12% of all drivers do not have a valid driver’s license

This means that $A = 0.12$

$A = a + (A \cap B)$

$0.12 = a + 0.04$

$a = 0.08$

The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about

$P = a + b + (A \cap B) = 0.08 + 0.02 + 0.04 = 0.14$

So the correct answer is:

e) 0.14

emmainna [20.7K]

Answer:

10x−31

Step-by-step explanation:

Let's simplify step-by-step.

10x+9−40

=10x+9+−40

Combine Like Terms:

=10x+9+−40

=(10x)+(9+−40)

=10x−31

Hope this helps and can you please give me brainliest ;-)

What is $20.00 less than 2.5 times the price of $64.80

KatRina [158]

To figure this out youll have to multiply 64.80 by 2.5 first then youll get 162 after to figure out the answer you subtract 20 from that amount and get 142

What is 2 - 3y is less than or equal to 12? That was the question.

Ivenika [448]

Answer:

$2-3y\leq 12\\-2+2-3y\leq 12-2\\-3y\leq 10\\\frac{-3}{3}y\leq \frac{10}{3} \\y\geq \frac{10}{3}$
