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.

x + y = 12

.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.

Given:

The given expression is $\frac{4 d+28}{12 d+96} \cdot \frac{d^{2}+14 d+48}{d^{2}+9 d+14}$

We need to multiply the terms.

Multiplication of the terms:

Before multiplying the terms, first we shall find the factors of the quadratic equations.

Thus, we have;

$\frac{4 d+28}{12 d+96} \cdot \frac{(d+6)(d+8)}{(d+2)(d+7)}$

Factor out the common terms, we get;

$\frac{4 (d+7)}{12 (d+8)} \cdot \frac{(d+6)(d+8)}{(d+2)(d+7)}$

Let us cancel the common terms from the above expression.

Thus, we have;

$\frac{4 }{12 } \cdot \frac{(d+6)}{(d+2)}$

Simplifying, the term, we get;

$\frac{1}{3 } \cdot \frac{(d+6)}{(d+2)}$

Now, we shall multiply the terms.

Hence, multiplying the terms, we get;

$\frac{(d+6)}{3(d+2)}$

Thus, the multiplied value of the given expression is $\frac{(d+6)}{3(d+2)}$
