Kedwin has $150.00 and wants to buy a new pair of headphones that cost $175.00 plus 10% shipping. He decides to wait until the headphones go on sale. What is the smallest sale rate that he needs to be able to afford them? 10% 20% 25% 30%

25%

Step-by-step explanation:

Amount Kedwin has for the purchase = $150

Total cost of purchase :

Item cost =. $175

Shipping cost = 0.1 * 175 = 17.5

Total cost =. $(175 + 17.5) = $192.5

Smallest sale rate in other to afford the item:

At 10%

(1 - 0.1) * 192.5 = $173.25

At 20%

(1 - 0.2) * 192.5 = $154

At 25%

(1 - 0.25) * 192.5 = $144.375

Hence, smallest sale rate needwd is 25%

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
