Answer 1

Answer: 2n - 64

Step-by-step explanation:

If the vairiable n describes the unknown number, and there is twice the number, then we can use the term 2n.

We also have 64 less then that number, and less means to subtract. Therefore, the equation is 2n - 64.

Answer 2

Answer:

2n-64

Step-by-step explanation:

I believe this is the correct answer (Not exactly sure to be honest)

Twice a number means to multiply by 2, so you use the variable (n) and multiply it by 2. For subtracting 64, I believe you usually put it after the (2n) portion of the equation. You may have to flip it though, equation order is important and it's been a while since I've done these so apologies if it's wrong! Good Luck!

They want 2 5 5 2 ​ of this order to be red plums. What is the total amount, in pounds, of red plums the market plans to order this year?

Answers

Answer: 7 3/4 pounds

Step-by-step explanation:

Here's the correct question:

Last year, Bob's Market ordered 15 1/2 pounds of plums from a local orchard. This year, the market plans to order 1 1/4 times as many pounds of plums as were ordered last year. They want 2/5 of this order to be red plums. What is the total amount, in pounds, of red plums the market plans to order this year?

The amount of pounds of plum that is ordered this year will be:

= 15 1/2 × 1 1/4

= 31/2 × 5/4

= 19 3/8

Since they want 2/5 to be red plums, the total amount of red plums will then be:

= 2/5 × 19 3/8

= 2/5 × 155/8

= 310/40

= 7 3/4 pounds

multiple out and simplify (x+6)(x-2)

Answers

Answer:

x² + 4x - 12

Step-by-step explanation:

(x+6)(x-2)

=> (x*x) + (x*-2) + (6*x) + (6*-2)

=> (x²) + (-2x) + (6x) + (-12)

=> x² - 2x + 6x - 12

=> x² + 4x - 12

So, once you simplify this equation the answer you should get is, x² + 4x - 12.

A warehouse has shelves that can hold 8, 12 or 16 each shelf has section holding the same number of skateboards. What is the greatest number of skate boards that can be put in a section

Answers

Answer:

4 skate boards

Step-by-step explanation:

We solve this question using Greatest Common Factor method

We find the factors of 8, 12 and 16

The factors of 8 are: 1, 2, 4, 8

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 16 are: 1, 2, 4, 8, 16

Then the greatest common factor is 4.

Thereeft, ,the greatest number of skate boards that can be put in a section is 4 skate boards

What are the first 3 terms in. t(n)=-2n+7

Answers

Answer:

The first 3 terms of the sequence [tex]t(n)=-2n+7[/tex] are:

[tex]5, 3, 1[/tex]

Step-by-step explanation:

Given the sequence

[tex]t(n)=-2n+7[/tex]

Here [tex]n[/tex] represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

[tex]t(n)=-2n+7[/tex]

[tex]t(1)=-2(1)+7[/tex]

[tex]t(1)=-2+7[/tex]

[tex]t(1) = 5[/tex]

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

[tex]t(n)=-2n+7[/tex]

[tex]t(2) = -2(2) + 7[/tex]

[tex]t(2) = -4 + 7[/tex]

[tex]t(2) = 3[/tex]

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

[tex]t(n)=-2n+7[/tex]

[tex]t(3) = -2(3) + 7[/tex]

[tex]t(3) = -6 + 7[/tex]

[tex]t(3) = 1[/tex]

Therefore, the first 3 terms of the sequence [tex]t(n)=-2n+7[/tex] are:

[tex]5, 3, 1[/tex]

Sign out Fred's bedroom has an area of 54 square feet. The bedroom is 6 times as many square feet as Fred's closet. If the closet is 3 feet wide, what is the length of the closet?

Answers

Answer:

3 feet

Step-by-step explanation:

Area of bedroom = 54 square feet.

Area of closet = Area of bedroom / 6= 54/6= 9 square feet.

Area = length * breadth

9 =  length *3

length = Area/ width

length = 9/3= 3 feet.

As the bedroom is having 6 times the area of the closet we will divide the area of the bedroom by 6 to get the area of the closet ( 54/6= 9) . Area is obtained by multiplying the length and the breadth so we have the width which 3 feet , we divide the area with the width ( 9/3= 3) to get the length = 3 feet.

Max has three pieces of oak trim that are 7 inches, 11 inches, and 18 inches long. He wants to use them to make a triangular base for a candleholder. Will the pieces make a triangle? Explain your answer.​

Answers

Answer:

No

Step-by-step explanation:

Use triangle inequality theorem, which states

"The sum of the lengths of any two sides of a triangle is greater than the length of the third side."

The sum of two sides compared to the remaining side:

7 + 11 = 18 = 18 - not ok7 + 18 = 25 > 11 - ok11 + 18 = 29 > 7 - ok

The sum of two sides is equal to the third side. This makes it impossible to make a triangle. Therefore the answer is no.
