The ducks and horses have 64 legs altogether.
How many horses are there?

Answers

Answer 1
13 would be your answer.

Answer 2

Answer:

6 ducks and 13 horses

Step-by-step explanation:

x ducks

19-x horses

2x+4(19-x)=64

2x+76-4x=64

4x-2x=76-64

2x=12

x=6 ducks

19-x = horses

19-6=13 horses

I am pretty sure it’s 120%

Answer:

112%

Step-by-step explanation:

percentage change value formula

c2 =  X2  -  X 1       X   100

             X1                   1

WHERE,

C2 = RELATIVE VALUE

X2  = FINAL VALUE  ( TODAY'S VALUE)  = 32,860

X1 = INITIAL VALUE  (1992 VALUE) = 15,500

PERCENTAGE CHANGE = 100

C2 =   32860  -   15500   X   100

Find the cost of leveling a badminton court 132m long and 58 m broad at the rate of Rs. 80 per sq. m.

Answers

Answer:

Rs. 612,480

Step-by-step explanation:

Hi there,

Here the question asks us to find the cost of leveling a badminton court at the rate of Rs.80 per sq..

So by the word leveling we know that we have to find the area of the court in order to proceed further.

(I am assuming the court to be rectangular in shape).

Area of a rectangle = Length * Breadth

*Length = 132 meters

*Breadth = 58 meters

==> 132*58= 7656 m^2

So now that we got the area of the badminton court lets find the cost of leveling it ==>

Cost of leveling per meter^2 = Rs. 80

Area = 7656 m^2

==> 7656 * 80 = 612,480

So the cost would be Rs. 612,480

Big Red Gymnastics Academy charges an initial fee of $ 200 to rent its gym for birthday parties. The academy then charges an additional $75 per hour. Write an equation that gives the total cost of the gym as a function of gym time (in hours).

A. y= 75x - 200
B. y= 200x + 75
C. y= 75x + 200
D. y= 200 - 75x

Answers

Answer: C. y= 75x + 200

Step-by-step explanation:

Since they charge $75 an hour x represents the house and they charge an initial fee of $200 so you add that to the $75 an hour

Answer:

C

Step-by-step explanation:

The equation y  = mx + b helps use to solve this type of problem

We know the initial amount to rent the gym is $200, that will be our b for this case since it is the y-intercept. This is the y-intercept since that is the initial amount.

The slope for this equation will be 200 represented by m. The key term that represents this is out slope is per. "$75 per hour." Since the function is in hours we don't need to convert hours into another unit.

Now if we plug in the variables, we get the equation y = 75x + 200 which is what C is.

A pen costs twice as much as a pencil. If 7 pens and 12 pencils cost $6.50, find the cost of a pencil.

I know the answer (pencil $0.25, pen $0.5), but I need to figure out how the answer is solved.

Answers

1. Observe the problem

2. Make a system of linear equations

x is pens

y is pencil

As stated in the text, x=2y

x=2y

7x+12y=6.50

Using substitution,

7(2y)+12y=6.50

14y+12y=6.50

26y=6.50

y=0.25

Substituting it back into the first equation:

x=2(0.25)

x=0.5y=0.25
