Answer:

8(x/2) + 8(3/8) = 1(8)

8(x/2)..the two cancels out and you are left with 4x

8(3/8)..the 8 cancels and leaves with 3

1(8)=8

4x+3=8

Subtract the 3 from both sides to get the x term alone

4x=5

Divide both sides by x to get alone

x=5/4

What is the y1 of 3x-5y=20

Aliun [14]

Unsure of what you mean by "y1."

If you wish to solve this eqn for y, do this:
-5y = - 3x + 20,
-3x + 20
y = ---------------- = (3/5)x - 4 (answer)
-5

chet needs to buy 4 work shirts,all costing the same amount .the total cost before chet appplies a $25 gift certificate can be n

Rashid [163]

So for this problem, let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount.

Choose the correct product of (6x − 2)(6x + 2). (1 point)

Vanyuwa [196]

You did not give any choices but this can easily be solved using the FOIL method.

FOIL stands for First, Outside, Inside, Last.

In your equation you have (6x-2)(6x+2)
You will multiply the terms that correspond to each letter

First: Means first terms of each set. In this case 6x and 6x
6x x 6x = $36x^{2}$ Now you have your first term in the sequence.

Outside: Means terms found in the outside areas of the whole equation, in this case it is 6x and 2
6x x 2 = 12x Now this is the second term

Inside: Means terms found in the inside areas of the whole equation, in this case it is -2 and 6x
-2 x 6x = -12x Now this is your third term

Last: Means the last terms of each set. In this case it is -2 and 2
-2 x 2 = -4 This is your last term

Now you have what you need for your new equation:

$36x^{2} + 12x -12x - 4$

Because your second and third terms are like terms, you can combine them by doing the operation indicated. 12x-12x = 0 so now you can cancel it out from your equation and your left with:

$36 x^{2} - 4$ This is your product
