Answer:

One of the most common algebraic symbols is the use of x, y or another letter of the alphabet to indicate a variable or unknown quantity. Common symbols used in algebra also include those related to equality, inequality, factorials and organization, like braces, brackets and parentheses.

Answer:

different variables represent unknown numbers.

Step-by-step explanation:

For example the equation 5x = 15

X is a variable that represents an unknown number. To get the unknown number in the example you need to divide 15 by 5 and 5 by 5 to get X alone and then X will equal 3.

So 5×3=15

I hope this helps

Erica can paint her room 5 hours .If she had her friend Rachel help her , they can paint the room together in 3 hours .How long
LUCKY_DIMON [66]

Answer:

7 hours 30min

Step-by-step explanation:

Step one :

Given data

We are told that Erica can paint 1 room in 5hours

Her work rate is 1/5 room per hour

And also with the assistance of her friend they can paint 1 room in 3 hours

Hence their combined work rate is 1/3 room per hour

Step two

The combined work expression is

1/A+1/B=1/T

Where A=Erica's work rate

B=Rachael's work rate

T=combined work

1/5+1/B=1/3

1/B=1/3-1/5

1/B=5-3/15

1/B=2/15

B=15/2

B=7.5 hours

It will take Rachel 7 hours 30min to paint the room

Given the equation y = 2 x - 8, what is the slope and the y -intercept?
jeka94

Answer:

m=2 and b=-8

Step-by-step explanation:

This equation is organized in slope-intercept form, y=mx+b. In this form, m is the slope and b is the y-intercept.

When given the equation, y=2x-8, we can see that 2 is in the place of m and -8 is in the place of b. The reason the y-intercept isn't 8 is that y=2x-8 can be written as y=2x+(-8) since y=mx+b involves addition. Therefore, the slope is 2 and the y-intercept is -8.

m=2 and b=-8

I hope this helps!

Someone please answer<br> 2.1 ( x + 5 ) = 7
tatuchka [14]
Since we have the 2.1 next to the parenthesis, we need to first distribute.

2.1 * x  &   2.1 * 5

2.1x + 10.5

Then we take that and add the equals seven to the problem to move onto the next step.

2.1x + 10.5 = 7

We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.

2.1x + 10.5 = 7
       - 10.5   -10.5

2.1x = -3.5

To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.

2.1x = -3.5
/2.1     /2.1

x = 1.66666666667

Hope this helped!
