Find the sale price of a $15 item after a 20% discount.

Answers

Answer:

Step-by-step explanation:

find 20% of 15 and then take that away from the 15

What you would do is X/15 and 20/100 Now cross multiply so x100 = 15 x 20 15 x 20 = 300, but you need to have x by it self so 300/100 = 3

3x + 2 + x = x + 5

6 − x − 3 = 4(x − 2)

4x − 2 − 2x = x − 5

−(x + 3) = 2x − 6

Answers

Answer:

x=1

Step-by-step explanation:

You need to add the Numbers with an x together as if they were racist on each side so you'd have

4x+2 = x+5

Then to move them to either side you must do the opposite symbol of what they are so if their positive their now negative

4x-x=-2+5

then add them together

3x= 3

then divide the normal number with the number with the x

x=1

For the next problem you Multiply thr number that are in the paranthases by the number on the outside so

6-x-3 = 4(x-2)

6-x-3= 4x-8

then copy the steps that I told you from last problem

-9-x=4x-8

then

-9+8=x+4x

thenn

-1=5x

divide

Answer:

Step-by-step explanation:

so you can always put a 1 infront of a stand alone x making 1x + 6 - 6x + 10

i also like to do a little trick were you can change the subtraction sign to an addition if you make what you subtraction negitive

so we have 1x + 6 + -6x + 10

we can add 6 and 10 and 1x and -6x make an end result of

-5x + 16

(or the other way since it is addition)

Answers

Answer:

a = 5, b = -1

Step-by-step explanation:

Simplify the left side.

Multiply both numerator and denominator by the conjugate of the denominator:

(√3 - 1)/(√3 + 1) = (√3 - 1)(√3 - 1)/(√3 - 1)(√3 + 1) =(√3² - 2√3 + 1)/(3 - 1) =(10 - 2√3)/2 = 5 - √3

Compare this to the right side to get:

5 - √3 = a + b√3a = 5, b = -1

16x2+10x−27=−6x+5

Step 1: Subtract -6x+5 from both sides.

16x2+10x−27−(−6x+5)=−6x+5−(−6x+5)

16x2+16x−32=0

Step 2: Factor left side of equation.

16(x−1)(x+2)=0

Step 3: Set factors equal to 0.
