You would add up the percentages first, which would bring everything up to 35%. You would then take the original cost of the item, which is $30 and multiple it by the 35%. 

The equation would look like...

30 x .35 = 

This will give you $10.50, which isn't the final answer.

You would then subtract 10.50 from the $30 that was asked for at the beginning by the retailer. 

Your final answer is $19.50. :) Which isn't a bad deal if I say so myself.

Distribute property to simplify 4(3x+2)
Julli [10]

Here is the equation:

4(3x+2)

Since 4 is next to the parentheses, you have to multiply everything in the parentheses by 4.

First multiply 3x by 4:

3x \times 4 = 12x

Now multiply 2 by 4:

4 \times 2 = 8

Now add them together:

12x+8 = 12x +8

Your answer is <u>12x + 8</u>

Help me with this two problems please <br> (The problema are in a picture):
Sav [38]

Answer:

Hey there!

I would prefer method two.

Both methods give the right solution, but method two is more straightforward. Instead of distributing, you simply divide and don't need to do as much work.

Let me know if this helps :)

What is the equation in slope-intercept form of the line
kari74 [83]

Answer:

-5/2x+3

Step-by-step explanation:

you reciprocate the slope since you are trying to find a line perpendicular.

From this m=2/5 to -5/2

then use the formula y-y1 =m(x-x1)

then you put in the points

y - - 2= -5/2(x- 2)

y+2= -5/2x +5

-2            -2

y= -5/2+ 3
