Answer:

<h2>50</h2>

Option D is the correct option

Solution,

Let no.of ducks be X

Let no.of goats be y.

Total heads= X+y=80 ➡️ equation (i)

Total legs= 2x+4y=260➡️ equation (ii)

X= 80-y

2(80 - y) + 4y = 260 \\ or \: 160 - 2y + 4y = 260 \\ or \: 160  + 2y = 260 \\ or \: 2y = 260  - 160 \\ or \: 2y = 100 \\ or \: y =  \frac{100}{2}  \\ y = 50

Number of goats= 50

Hope this helps...

Good luck on your assignment...

Shawna and her best friend Keisha go shopping.
amid [387]

Answer:

138

Step-by-step explanation:

p(x) = 3x^4 + 2x^3 − 4x^2 + 21

Let x = 2

p(2) = 3*(2)^4 + 2*(2)^3 − 4*(2)^2 + 21

       = 3*16+2*8-4*4+21

       =48+16-16+21

        = 69

This is per girl

There are 2 girls

2 * 69

4(p - 7) = 44
First distribute the 4 over the parentheses
4p - 28 = 44
Add 28 to both sides:-
4p = 44 + 28
4p = 72
Divide both sides by 4:-
p = 72/4
p = 18 (answer)

Original price of a CD: $20.00 <br> Discount 42% <br> Tax 6%
vodomira [7]
First, we can subtract the discount from the original price. Divide the discount (42%) over 100.

42/100 = 0.42

Next, we need to multiply. It's basically asking what 42% of 20 is. 

0.42 × $20 = $8.40

Now, we know that we will have $8.40 on the CD because of the discount. We can subtract the saved amount from the original amount to get the price.

$20 - $8.40 = $11.60

You will pay $11.60 for the CD without taxes.

----------

Now to add the taxes.... To do this, do the same first step we did when finding the discount price. 

6/100 = 0.06

Multiply. Like I said, you can think of it as, '6% of 11.60'. 

0.06 × 11.60 = $0.70

Last step is to ADD. Since taxes add more money onto the current price, we will have to add.

$11.60 + $0.70 = $12.30

---------

The total price of the CD will be: $12.30.
