I need help With this question

Answer:

25

Step-by-step explanation:

When calculating a percentage of a number always multiply it by the percentage divided by 100. In this case that would be 0.05, 500*0.05=25

Answer:

[tex]x= 6[/tex]

[tex]y = -2[/tex]

Step-by-step explanation:

Given

[tex]SW = 2x + y[/tex]

[tex]WC = x - 2y[/tex]

[tex]SC = 20[/tex]

Required

Determine x and y

Since W is the midpoint;

[tex]SW = WC = \frac{1}{2} * SC[/tex]

[tex]SW = WC = \frac{1}{2} * 20[/tex]

[tex]SW = WC = 10[/tex]

Substitute 10 for SW and WC

[tex]2x + y = 10[/tex] --- (1)

[tex]x - 2y = 10[/tex] ---- (2)

Make x the subject in (2)

[tex]x = 10 + 2y[/tex]

Substitute [tex]x = 10 + 2y[/tex] in (1)

[tex]2(10 + 2y) + y = 10[/tex]

[tex]20 + 4y + y = 10[/tex]

[tex]20 + 5y = 10[/tex]

Solve for 5y

[tex]5y = 10 - 20[/tex]

[tex]5y = -10[/tex]

Solve for y

[tex]y = -10/5[/tex]

[tex]y = -2[/tex]

Recall that [tex]x = 10 + 2y[/tex]

[tex]x = 10 + 2(-2)[/tex]

[tex]x = 10 -4[/tex]

[tex]x= 6[/tex]

Answer:

B. False

Step-by-step explanation:

If the decimal goes on and on forever and never stops or begins to repeat predictably, it's irrational. If the decimal stops after a finite number of digits or begins to repeat predictably, it's rational.

Answer:

A) [tex]\frac{wx}{6}[/tex]

Step-by-step explanation:

[tex]\frac{3wx}{6x}\cdot \frac{3wx}{9w}[/tex]

Multiply:

[tex]\frac{3wx\cdot \:3wx}{6x\cdot \:9w}[/tex]

Cancel off the common factor "w":

[tex]\frac{3x\cdot \:3wx}{6x\cdot \:9}[/tex]

Cancel off the common factor "x":

[tex]\frac{3\cdot \:3wx}{6\cdot \:9}[/tex]

[tex]\frac{9wx}{54}[/tex]

Cancel off the common factor "9":

[tex]\frac{wx}{6}[/tex]

Answer:

it is a rational number

Step-by-step explanation:

Answer:

x = n + 2 + 3 + 4 + 5 + 6

Step-by-step explanation:

Answer:

Ok, if we start with a number n, then we can write the consecutive numbers of n as:

n + 1

n + 2

n + 3..

etc.

Now, suppose that we have an integer x, and we want to write it as a sum of consecutive numbers.

There is a really trivial way.

We know that x + 0 = x.

now, we can write:

0 = (x - 1) + (x - 2) + ... + 1 + 0 + (-1) + (-2) + ..... + (-x + 2) + (x - 1)

Then we wrote zero as a sum of consecutive numbers.

Now we can write:

x = x + 0 = x + (x - 1) + (x - 2) + .... + 1 + 0 - 1 - 2 - ... - (x - 1) = x

Then we show that for any integer x, we can write it as a sum of consecutive integers.

Then it must work for all the integers x, then we prove that all the integers can be written as a sum of consecutive integers.

Step-by-step explanation:

a term is any number seperated by a sign

-9 is the term

Steps to solve:

3/x+2 - √x-3 when x = 19

~Substitute

3/19+2 - √19-3

~Simplify

3/21 - √16

~Simplify

1/7 - 4

~Subtract

-3 6/7

Answer:

Hi there!

Your answer is:

To isolate y that has a fraction, multiply by the inverse of the fraction! This is called the multiplicative inverse property!!

Y is equal to:

y = 2/3 x + 2 & 2/3

Step-by-step explanation:

Heres a break down of how to do this:

-3/4y = -1/2x -2

Multiply both sides by -4/3!

-4/3 × -3/4 = -12/12 (which equals -1!!)

y = -4/3 (-1/2x -2)

y = 2/3 x + 2 & 2/3

I hope this helps you! If you need clarification let me know!

[tex]40-50d[/tex]

Step-by-step explanation:

Use the distributive property:

[tex]10(4-5d)\\\\10(4)-10(5d)\\\\40-50d[/tex]

Since these are not like terms, they can't be further simplified.

Answer:

The value of the expression is 4

Step-by-step explanation:

Given:

Evaluate 4 - 0.25g + 0.5h

When g = 10 and h = 5

Substitute the value of g and h into the expression

4 - 0.25g + 0.5h

= 4 - 0.25(10) + 0.5(5)

= 4 - 2.5 + 2.5

= 4

Therefore, the value of the expression is 4

Answer:

-8/15

Step-by-step explanation:

Answer:

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (-5,9), B (5,7)

The midpoint is

[tex]M = ( \frac{ - 5 + 5}{2} \: , \: \frac{9 + 7}{2} ) \\ = ( \frac{0}{2} \: , \: \frac{16}{2} )[/tex]

We have the final answer as
