Answer:

The price of hot dog is $2.5 and that of a pretzel is $1.25.

Step-by-step explanation:

Let the cost of hotdogs be x and that of pretzels be x.

So,

4x+3y = 13.75 ...(1)

and

2x+5y = 11.25 ...(2)

Multiply equation (2) by 2.

4x+10y = 22.5 ...(3)

Subtract equation (1) from (3).

4x+10y-(4x+3y) = 22.5-13.75

4x+10y-4x-3y = 8.75

7y = 8.75

y = 1.25

Put the value of y in equation (1).

4x+3(1.25) = 13.75

4x+3.75 = 13.75

4x = 13.75-3.75

4x = 10

x = 2.5

So, the price of hot dog is $2.5 and that of a pretzel is $1.25.

A nature preserve worker calculates there are 6,000 deer in Sharon Woods Park. She also estimates that 75 more deer die than are

Nikolay [14]

The linear equation used to represent this situation is y = -75x + 6000

A linear equation is in the form:

y = mx + b;

where y, x are variable, m is the slope of the line and b is the y intercept.

Let y represent the amount of deer present in x years. There are 6000 deer presently, hence a = 6000. Also 75 more deer die than are born each year. Hence m = -75.

The linear equation is given by:

y = -75x + 6000

In 3 years:

y = -75(3) + 6000

y = 5775

For there to be 5325 deer:

5325 = -75x + 6000

x = 9 years

HELP ME PLEASE?? :( HELP ME

Crazy boy [7]

I really dislike long simplification times 4 questions so I will jsut put the answers on some of them

1. remember that the denomenator cannot equal zero so find what values will and restrict them
the answer is the third one or $\frac{3}{(x+6)(x-1)}$

2. second one
(3x-2)/(5x)

3. what you would do is factor the top and divide factors making ones
answer is the fourth one or $\frac{2(3x^{2}-7)}{2x^{2}+3}$

4. find the LCM of the denoemators
4x and 2
4x=2 times 2 times x
2=2
LCM=4x
answer is the third one or 4x

ANSWERS:
1. third
2. second
3. fourth
4. third
