<span>Simplifying 2x + n = 3

Reorder the terms: n + 2x = 3
Solving n + 2x = 3

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-2x' to each side of the equation. n + 2x + -2x = 3 + -2x

Combine like terms: 2x + -2x = 0 n + 0 = 3 + -2x n = 3 + -2x

Simplifying n = 3 + -2x</span>

Can someone help me solve this?

Dovator [93]

Answer:

5 felt pads.

7 cards.

Step-by-step explanation:

Remark

The total number of items is 12
So let the felt sheets be x
Let the cards = y

Equations and Solution

x + y = 12

Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.

0.5x + 0.75y = 7.75 Multiply this equation by 2

x + 1.5y = 15.50 write the first equation underneath and subtract.

<u>x + y = 12</u>

.5y = 3 Divide by 0.5

y = 3/0.5

y = 7

So she can get 7 cards.

x + y = 12

x + 7 = 12

x = 12 - 7

x = 5

So she can buy 5 felt pads.

Answer:

1) $\frac{1}{2^7}$ ; 2) $11^7$

Step-by-step explanation:

1) Using the Power of a Fraction Rule $(\frac{a}{b} )^x = (\frac{a^x}{b^x} )$ ,

$(\frac{1}{2} )^7 = (\frac{1^7}{2^7} )$ , which can just be simplified to $\frac{1}{2^7}$ .

2) Using the Negative Exponent Rule, $a^{-x} = \frac{1}{a^{x}}$ ,

$(\frac{1}{11} )^{-7} = \frac{1}{\frac{1}{11^7}}$ , which can be simplified to $11^7$ .
