Brownies are now on sale. Each brownie costs $0.20 less than the original price. Right now, if you buy 8 of them it will cost $1

Airida [17]

Answer: The original price of brownie was $2.1 each.

Step-by-step explanation:

since we have given that

Let the original price will be x

Number of brownie purchased = 8

According to question , each brownie costs $0.20 less than the original price.

So, it becomes

$8\times (x-0.20)=\$15.20\\\\8x-1.6=15.20\\\\8x=15.20+1.60\\\\8x=16.8\\\\x=\frac{16.8}{8}\\\\x=\$2.1$

Hence, the original price of brownie was $2.1 each.

Enter the correct answer pls help

Phoenix [80]

Answer:

$\huge\boxed{\sf x = 8a}$

Step-by-step explanation:

$\sf \frac{3}{a} x - 4 = 20\\\\Add \ 4 \ to \ both \ sides\\\\\frac{3}{a} x = 20+4\\\\\frac{3}{a} x = 24\\\\Multiply \ both \ sides \ by \ a\\\\3x = 24 * a\\\\Divide \ 3 \ to \ both \ sides\\\\x = 24a / 3\\\\x = 8a\\\\\rule[225]{225}{2}$

Hope this helped!

Determine if the ordered pair (6, 4) is a solution to the inequality

kvasek [131]

Answer:

Step-by-step explanation:

all we need to do is to plug the point (6,4) in the inequality and see if it satisfies it :

pay attention that here we have x=6 y=4

4< $\frac{3}{4} (6) - 3$

we simplify we get :

4<4.5-3

4<1.5 which is incorrect so (6,4) is not a solution. moreover

notice that 4 is > than 1.5 so the point lies above the line

thus the answer is : A

you can also solve this problem by graphing the line $y=$ $\frac{3}{4} x-3$ and plotting the point (6,4) and hence you will notice that the point is above the line
