From the sum of 3x+ 5y -2 and 2x-3y +1 subtract the sum of 4x -8y +3 and -5x + 6y +7

Answers

Answer 1

Answer:

Answer:

First, let's simplify both sums by combining like terms:

3x + 5y - 2 + 2x - 3y + 1 = 5x + 2y - 1

4x - 8y + 3 - 5x + 6y + 7 = -x - 2y + 10

Now we can subtract the second sum from the first:

(5x + 2y - 1) - (-x - 2y + 10) = 5x + 2y - 1 + x + 2y - 10

Simplifying this expression, we get: 6x + 4y - 11

Convert base 2 number 10001 in decimal?

Answers

To convert a base 2 (binary) number to decimal, we can use the following method:

Starting from the right, multiply the value of each binary digit (0 or 1) by 2 raised to the power of its position, where the position of the rightmost digit is 0, the one to its left is 1, and so on. Then, add up these values to get the decimal equivalent.

For the binary number 10001:

1 * 2^4 + 0 * 2^3 + 0 * 2^2 + 0 * 2^1 + 1 * 2^0

= 16 + 0 + 0 + 0 + 1

= 17

Therefore, the decimal equivalent of the binary number 10001 is 17.

A circle has a circumference of 2 pi cm. Which statement about the circumference and area is true? A comparison of the area and circumference is not possible since the area cannot be determined. The numerical values of the circumference and area of the circle are equal. The numerical value of the circumference is greater than the numerical value of the area. The numerical value of the circumference is less than the numerical value of the area.

Answers

Answer:

Third option: The numerical value of the circumference is greater than the numerical value of the area.

Step-by-step explanation:

The area of a circle can be calculated with this formula:

$A=\pi r^2$

Where "r" is the radius of the circle.

The circumference of a circle can be calculated with this formula:

$C=2\pi r$

Where "r" is the radius of the circle.

In this case you know that:

$C=2\pi \ cm$

Then, if you subsitute this value into the formula $C=2\pi r$ and you solve for "r", you get that the radius of the circle is:

$2\pi \ cm=2\pi r\n\nr=( 2\pi \ cm)/(2\pi) \n\nr=1\ cm$

Then, substituting the radius into the formula for calculate the area of a circle adn evaluating, you get that its area is:

$A=\pi (1\ cm)^2\n\nA=\pi \ cm^2$

Based on the obtained, you can identify that:

$2\pi >\pi$

Therefore, the numerical value of the circumference is greater than the numerical value of the area.

Answer:

C: The numerical value of the circumference is greater than the numerical value of the area.

What is the greatest common factor of 18 and 35

Answers

The greatestcommonfactor of 18 and 35 is 1.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the liketerms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The greatestcommonfactor of 18 and 35.

Now,

See all the factors of 18.

= 1, 2, 3, 6, 9, and 18.

See all the factors of 35.
= 1, 5, 7, and 35.

We see that,

The greatestcommonfactor is 1.

Thus,

The greatestcommonfactor of 18 and 35 is 1.

of the dinner equally. However, since Matthew's dad provided concert tickets for the
group, the friends agree that Matthew doesn't have to help pay for the car service.
The friends divide this cost equally among themselves. If each friend spends a total of
$30, how many friends went to the concert with Matthew?
