What is 10x-2(x+6)=52 ?

Answers

Answer:x=8

Step-by-step explanation:Reorder the terms:

10x + -2(6 + x) = 52

10x + (6 * -2 + x * -2) = 52

10x + (-12 + -2x) = 52

Reorder the terms:

-12 + 10x + -2x = 52

Combine like terms: 10x + -2x = 8x

-12 + 8x = 52

Solving

-12 + 8x = 52

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12' to each side of the equation.

-12 + 12 + 8x = 52 + 12

Combine like terms: -12 + 12 = 0

0 + 8x = 52 + 12

8x = 52 + 12

Combine like terms: 52 + 12 = 64

8x = 64

Divide each side by '8'.

x = 8

Simplifying

x = 8

show that n(n+1)(n+2) is divisible by 6
Solution
(​

Answers

Proof by induction

Base case:

n=1: 1*2*3=6 is obviously divisible by six.

Assumption: For every n>1 n(n+1)(n+2) is divisible by 6.

For n+1:

(n+1)(n+2)(n+3)=

(n(n+1)(n+2)+3(n+1)(n+2))

We have assumed that n(n+1)(n+2) is divisble by 6.

We now only need to prove that 3(n+1)(n+2) is divisible by 6.

If 3(n+1)(n+2) is divisible by 6, then (n+1)(n+2) must be divisible by 2.

The "cool" part about this proof.

Since n is a natural number greater than 1 we can say the following:

If n is an odd number, then n+1 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted.

If n is an even number" then n+2 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted.

Therefore by using the method of mathematical induction we proved that for every natural number n, n(n+1)(n+2) is divisible by 6. QED.

Omar's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs $4.10 Omar per pound, and type B coffee costs $5.30 per pound. This month, Omar made 141 pounds of the blend, for a total cost of $640.50. How many pounds of type A coffee did he use?

Answers

Hey there! I'm happy to help!

Let's use the variables A and B to represent the number of pounds used of types A and B.

4.10A+5.30B=640.50

A+B=141

Let's rearrange the bottom equation to solve for B.

A+B=141

Subtract A from both sides.

B=141-A

We can put this value of B into the first equation to solve for the number of pounds of type A Omar used.

4.10A+5.30(141-A)=640.5

We use distributive property to undo parentheses.

4.10A+747.3-5.3A=640.5

We combine like terms.

-1.2A+747.3=640.5

Subtract 747.3 from both sides.

-1.2A=-106.8

Divide both sides by -1.2

A=89

Omar used 89 pounds of type A coffee in this month's blend.

Kaleb can skateboard 75 feet in 25 seconds. How far can he skateboard in 3.25 minutes?

Answers

Answer:

585 Feet

Step-by-step explanation:

First, you have to consider how much seconds in a minute. 60.

Then, multiply 75 feet to make it match to 60 seconds. So 60/25. You get 2.4. You multiply 2.4 by 75 to get 180 feet per minute.

Finally, you multiply 180 by 3.25, as it is 3.25 minutes.

he can go 3 feet per a second, so there are 195 seconds in 3.25 minutes so you would do 3 x 195 giving you an answer of 585 feet in 3.25 minutes

Use the number line to find 1/4+-21/8

Answers

[tex]-\frac{19}{8}[/tex]

Step-by-step explanation:

[tex]\frac{1}{4}-\frac{21}{8}=\frac{2}{8}-\frac{21}{8}=\frac{2-21}{8}=-\frac{19}{8}[/tex]

The required number line represents 2 whole intervals (16/8) and then 7 more parts (7/8) from 0, and ends up at the point marked 2 3/8.

What is Number Line?

In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.

To add fractions with different denominators, we need to find a common denominator. In this case, we can use 8 as the common denominator:

1/4 + -21/8

1/4 - 21/8

2/8 - 21/8

-19/8

-2 3/8

To represent 19/8 on a number line, we need to divide the interval between 0 and 3 into 8 equal parts, and then count 23 of these parts from 0.

The number line would look something like below as shown.

Thus, the required number line represents 2 whole intervals (16/8) and then 7 more parts (7/8) from 0, and ends up at the point marked 2 3/8.

Answers

Answer:

Step-by-step explanation:

Suppose pieces of chocolate pie served at a restaurant average 350 calories with a standard deviation of 20 calories. Calories have a Normal distribution due to inexact cutting of the pies. Which graph represents the proportion of pieces of pie that have more than 375 calories.

Answer: The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and for a negative z score means the  raw score is below the mean. The z score is given as:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Given that: μ = 350 calories, σ = 20 calories, x > 375

[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{375-350}{20}=1.25[/tex]

From the graph, The shaded area represents the proportion of pieces of pie that have more than 375 calories

From the normal distribution table, P(x > 375) = P(z > 1.25) = 1 - P(z < 1.25)

= 1 - 0.8944 = 0.1056 = 10.56%

An oil tanker can be emptied by the main pump in 4 hours. An auxiliary pump can empty the tanker in 11 hours. If the main pump is started at 7 PM​, when should the auxiliary pump be started so that the tanker is emptied by 10 PM​?

Answers

Answer:

The pump should be added by 8PM

Step-by-step explanation:

An oil tanker can be emptied by the main pump in 4 hours.

An auxiliary pump can empty the tanker in 11 hours.

the main pump is started at 7 PM,and we have 10 PM - 7PM = 3 hours to empty the tank.

So we have to look for the combined rate of the both pumps .

Let's say the volume= x

Rate of first pump= x/4

Rate of second pump= x/11

The rate will be added together

Combined rate= x/11 + x/4

Combined rate= 15x/44

But they have three hours to complete their pump

15x/44 = 3

X=1.0227

The pump should be added by 8PM
