(15-6)-3 = 15 - (6 -3) dose this make sense or nonsense?

solmaris [256]

No it does not make sense. You misused the parenthesis and the "-" multiplied the variables within the parenthesis and as a result one of them subtracted (15 - 6) by 3 and the other added, which is why the final values are 6 apart. This is not how you use properties in math.
(15 - 6) - 3 = 9 - 3 = 6
15 - (6 - 3) = 15 - 3 = 12

Total consumption of fruit juice in a particular country in 2006 was about 1.85 billion gallons. The population of that country

Eduardwww [97]

Given :

Population of country in 2006 , P = 300 million.

Consumption of fruit juice in 2006 by while population, C = 1.85 billion.

To Find :

The average number of gallons of fruit juice consumed per person in the country in 2006.

Solution :

We know, 1 billion = 1000 million.

C = 1.85 billion = 1850 million.

Now, average umber of gallons of fruit juice consumed per person in the country in 2006 is :

$c =\dfrac{C}{P}\\\\c=\dfrac{1850}{300}\ gallons/person\\\\c=6.17 \ gallons/person$

Hence, this is the required solution.

Please help me !!!! Will mark brainliest

Answer:

The value of x is 108°

Step-by-step explanation:

Given interior angles of parallelogram are:

$\frac{2}{3}x, x, \frac{2}{3}x\ and x$

The sum of interior angles of a parallelogram is 360°.

We will use this information to find the value of x.

So adding up all the angles and putting the sum equal to 360 we get,

$x+\frac{2}{3}x+x+\frac{2}{3}x = 360$

$2x+\frac{2}{3}x+\frac{2}{3}x = 360\\2x + \frac{4}{3}x = 360$

Taking LCM on left side of the equation, as it involves fraction

$\frac{6x+4x}{3} = 360\\\frac{10x}{3} = 360$

Multiplying both sides by 3

$\frac{10x}{3} * 3 = 360 * 3\\10x = 1080$

Dividing both sides by 10

$\frac{10x}{10} = \frac{1080}{10}\\x = 108$

Hence,

The value of x is 108°

25 POINTS HELP PLEASE! Complete the table and pattern. Determine the common difference. Write the explicit rule.

Mumz [18]

Answer:

Look below for the answers.

Step-by-step explanation:

What I'm going to do is one of these very carefully and leave the other 2 to you. They follow exactly the same pattern and once you see one of them done, you should be able to do any of them.

Six

Step one

Find the common difference.

Two values on the second line are always together so subtract the higher number one from the lower numbered on.

n = 3 and n = 4 on this question are side by side. That is you have f(4) and f(3)

ALWAYS subrract the lower numbered one from the higher numbered one

d = f(4) - f(3) = 60 - 64 = - 4

Step Two

Find the first term.

The first term is ALWAYS f(1). Always. There is never any kind of exception. f(1) in this case is 72

Step Three

Write the general explicit term

The general formula for the explicit Formula is ALWAYS

tn = first term + (n -1)*d

first term = 72

d = - 4 from above.

Explicit formula = 72 + (n - 1)*(-4) So the fifth term is

Example

t5 = 72 + (5 - 1)*(-4)

t5 = 72 + 4*(-4)

t5 =72 - 16

t5 = 56

Step Four

Write the Recursive formula

It is always in the same formal

tn = t_(n - 1) + (common difference)

tn = t_(n - 1) - 4 in this case

Example

Find t2

t2 = t1 - 4

t2 = 72 - 4

t2 = 68

If you do the other two, you can leave them in my PM and I will mark them.
