Answer:

The answer to this equation is 7.5

Step-by-step explanation:

What I did is started with PEMDAS:

6÷2 (1 + 2) ÷4 (4 + 5) ÷ 6

          ^               ^

         (3)            (9)

Now the 3 and the 9 are what are in the ()

6÷2 = 3... 3  (3) = 9.

9 ÷ 4 = 5.

The 9 from earlier is still in parenthesis...

Take 5 and the 9 in parenthesis and multiply (If a single number is in (), It means to multiply anyway)

5 (9) = 45

The Final Step is to divide by 6

45 ÷ 6 =  (FINAL) 7.5

I hope this helped! (:

Answer:

[tex]3\frac{3}{8}[/tex]

Step-by-step explanation:

6 ÷ 2(1+2) ÷ 4(4+5) ÷ 6 =​

----------------------------------------

By order of operations, parentheis comes first.

6 ÷ 2*(1+2) ÷ 4*(4+5) ÷ 6 =​

6 ÷ 2*(3) ÷ 4*(9) ÷ 6=

----------------------------------------

Next comes multiplication and division. Now, we can remove  the parentheis and solve from left to right.

6 ÷ 2*(3) ÷ 4*(9) ÷ 6=

6 ÷ 2*3 ÷ 4*9 ÷ 6=

3*3 ÷ 4*9 ÷ 6=

9 ÷ 4*9 ÷ 6=

27/8=

Answer:

f(n) = 155 - 14(n-1) [Question 1, Arithmetic sequence]

f(15) = -41 [Question 2, 15th term]

Step-by-step explanation:

Given the explicit formula for an arithmetic sequence: f(n) = f(1) + d(n-1).

Where d is the common difference, f(n) is the nth term, and f(1) is the first term.

Given that the first term f(1) is 155 from the table since 1 is n, and 155 is f(n). And the second term f(2) is 141 since n is 2, and 141 is under f(n) on the table when n is 2.

Subtract the two terms to find the common difference: d = f(2) - f(1) = f(3) - f(2) = f(4) - f(3) = ...

d is 155-141= -14.

Remember how the first term in the sequence is 155, and how d is -14, we can make this into an equation:

f(n) = f(1) + d(n-1) → f(n) = 155 - 14(n-1).

We can test this by matching the equation by input, and output to the table:

f(1) = 155 - 14(1-1) = 155

f(2) = 155 - 14(2-1) = 155 - 14 = 141

f(3) = 155 - 14(3-1) = 155 - 28 = 127

f(4) = 155 - 14(4-1) = 155 - 42 = 113

f(5) = 155 - 14(5-1) = 155 - 56 = 99

......

f(15) = 155 - 14(15-1) = 155 - 196 = -41

Answer:

Your question might have an error :( All inequality equations have to have a inequality symbol somewhere in the equation. Yours dont have one but no worries. I'll see what I can do.

Based on your equation, that is not a inequality, so therefore your answer would have been: (-5x-16)

Step-by-step explanation:

If your equation was:

(-5x-10<-6) your answer would have been: x>-4/5

(-5x-10>-6) your answer would have been: x<-4/5

(-5x>-10-6) your answer would have been: x<16/5

(-5x<10-6) your answer would have been: x>-4/5

Those are all the possible outcomes of that equation :)

Please double check to make sure that is what the question states : )

Answer:

A

Step-by-step explanation:

Answer:

A. 5

Step-by-step explanation:

It is A. 5 because if you look at the factors of 15 and 20, there are two common factos in both of them. 1 and 5, but the questions is asking for the greatest common factor of 15 and 20. 5 is greater than 1, so 5 is the greatest common factor, making A the answer.

Answer:

[tex]m=8x-5-4\Delta x[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=4x^2-5x-1[/tex]

And we want to use the difference quotient:

[tex]m=\frac{f(x+\Delta x)-f(x)}{\Delta x}[/tex]

To find the slope function.

So, let's substitute [tex]x+\Delta x[/tex] for our function. This yields:

[tex]m=\frac{(4(x+\Delta x)^2-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]

Let's square. Use the perfect square trinomial pattern. This yields:

[tex]m=\frac{(4(x^2+2x\Delta x-\Delta x^2)-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]

Distribute:

[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)-(4x^2-5x-1)}{\Delta x}[/tex]

Distribute the right:

[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)+(-4x^2+5x+1)}{\Delta x}[/tex]

Combine like terms:

[tex]m=\frac{(4x^2-4x^2)+(-5x+5x)+(1-1)+(8x\Delta x-4\Delta x^2-5\Delta x)}{\Delta x}[/tex]

The first three terms will cancel. This leaves us with:

[tex]m=\frac{8x\Delta x-4\Delta x^2-5\Delta x}{\Delta x}[/tex]

We can factor out a Δx from the numerator:

[tex]m=\frac{\Delta x(8x-4\Delta x-5)}{\Delta x}[/tex]

The Δx will cancel. So, our slope function is:

[tex]m=8x-5-4\Delta x[/tex]

And we're done!

Answer:

Step-by-step explanation:

Move the decimal point in the divisor and dividend.

Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to the right. At the same time, move the decimal point in the dividend (the number you’re dividing) the same number of places to the right.

Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.

Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.

Line up each digit in the quotient just over the last digit in the dividend used in that cycle.

Answer:

.60 per can

Step-by-step explanation:

39 dollars divided by 60 cans

The ratio of the amount of money that Kristen paid to the number of cans gives the amount per can thus it will be $0.6 per can.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

Kristen paid $39 for 60 cans of corn.

Ratio of the amount to the number of cans,

39/60 = $0.6 per can

Hence "The ratio of the amount of money that Kristen paid to the number of cans gives the amount per can thus it will be $0.6 per can".
