Answers

Answer 1

Given

An algebraic expression is the difference between seven times a number and three times that number.

To find:

The algebraic expression.

Solution:

Let x be the unknown number.

Multiplication is used for times and subtraction is used for difference.

7 times of a number = 7x

3 times of that number = 3x

The difference between seven times a number and three times that number is

[tex]Difference = 7x-3x[/tex]

[tex]Difference =4x[/tex]

Therefore, the algebraic expression for the given statement is 7x-3x and its simplified form is 4x.

Answer 2

Answer:

I got you covered, friend!

the answer you want is 7x-3x

Step-by-step explanation:

7x-3x means the difference between seven times a number (x) and three times that number (also x)

$3000 is invested for a period of 3 years at a rate of 6% compound monthly. What will the balance in the account be at the end of 3 years?

Answers

Answer:

Hence, the total amount of money that the investor would have after 6 years will be $ 536.04 .

Step-by-step explanation

Answer:

Interest = $3573.048

Step-by-step explanation:

Given: $3000 is invested for a period of 3 years at a rate of 6% compound monthly. What will the balance in the account be at the end of 3 years?

The formula to compound interest is:

I = P(1 + R)^T

First, put in the terms:

I = $3000(1 + 6%)^3

Then calculate:

I = $3000(1 + [tex]\frac{6}{100}[/tex])^3

I = $3000(1 + 0.06)^3

I = $3000(1.06)^3, 1.06^3 = 1.191016

I = $3000 x 1.191016

I = $3573.048

A cylinder had a volume of 100 pi. Find one possible radius and height for the cylinder. Explain how you know your combination is correct.

Answers

Answer:

Calculate the volume of a cylinder using the formula V = r2 × π × h. Begin by first finding the area of the circle at one end. Square the radius of the circle and multiply the result by "pi" (the symbol π), or approximately 3.14. Multiply this result by the cylinder's height to get its volume.

Step-by-step explanation:

the height is 4 and the radius is 2

Dana bought 12 pizzas for a Math Club party. Some were pepperoni pizzas that $11.00 each,
and the rest were mushroom pizzas that cost $9.50 each. She paid $124.50 for the pizzas. How
many pepperoni pizzas did she buy

Answers

Answer:

7 pepperoni pizzas

Step-by-step explanation:

First, you take the biggest number and subtract it by 9.5 until you get a number that can be divided into 11 which is 77.

Answer:

7 pepperoni pizzas

Step-by-step explanation:

Where p = # of pepperoni pizzas and m = # of mushroom pizzas

124.50 = 11p + 9.5m

Now you need to guess and check:

Use this equation: (124.5 - 11 * p) / 9.5 and replace p with whole numbers until you get a whole number as the output

I got p=7 and m=5

So she bought 7 pepperoni pizzas

Factor the equation. [tex]x^2+12x+35[/tex]

Answers

Answer:

(x + 7)(x + 5)

Step-by-step explanation:

Given

x² + 12x + 35

Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (+ 12)

The factors are + 7 and + 5 , since

7 × 5 = + 35 and sum = 7 + 5 = + 12, then

x² + 12x + 35 = (x + 7)(x + 5) ← in factored form
