Jeri has a total of 40 pets with a total of 160 legs. If
she owns only cats and dogs, how many of each does
she have? Write a system of equations to represent
this situation. Solve it using any method.

Answers

Answer 1

Answer:

let x be the number of cats and y be the number of dogs:

x + y = 40

4x + 4y = 160

If you divide both sides of the second equation by 4, you will be left with:

x + y = 40

Then, subtract both equations:

x + y =40

- (x + y = 40)

0 = 0

Since you have a number = a number, there are infinite solutions.

What is the equation of the line that passes through the point (8, 4) and has a slope
of 3/2?

Answers

Answer:

y = (3/2)x - 8    slope-intercept form

3x - 2y = 16      standard form

Step-by-step explanation:

Use the point-slope form of a line to do this problem.

[tex]y - y_{1} = m(x - x_{1} )\\[/tex]

In your case [tex](x_{1} , y_{1} ) = (8, 4)[/tex]

So. y - 4 = 3/2 ( x - 8)  

multiply thru by 2

2y - 8 = 3(x - 8)

2y - 8 = 3x - 24

2y = 3x - 16

y = (3/2)x - 8    slope-intercept form

3x - 2y = 16      standard form

ax^2+bx+c is the first degree polynomial of x which of these letters equal zero?

Answers

First degree polynomials means that the maximum power x is raised up to that does not have a coefficient 0 is 1. And here we have a term ax^2 which means it could not be a first degree polynomial if a has a positive or negative value. Thus, letter a in this case should be 0 in order for this to be a first degree polynomial of x.

Step-by-step explanation:

2x +3y = 9
-3x +3y = -6

Answers

Rewrite the second equation:

This is to make the calculation easier. There are other ways to do this as well.

3y = 3x - 6

Substitute that into the first equation:

Since they are the same thing (=), it is possible to replace 3y.

2x + (3x - 6) = 9

Solve the equation:

2x + 3x = 9 + 6

5x = 15

x = 3

Substitute x = 3 into the first equation:

2(3) + 3y = 9

6 + 3y = 9

3y = 3

y = 1

Answer: x = 3, y = 1

Work out the 30th term in the sequence.

Answers

Answer:

88

Step By Step

Step-by-step explanation:

An arithmetic sequence is defined as

an=a+d(n-1) where an=nth term, a=initial term, n=term number, and d=common difference

For sequence 1,4,7... a=1 and d=4-1=7-4=3 so

an=1+3(n-1)

an=3n-2, so the 30th term is

an=3(30)-2

an=88

Total pounds of candy bought = 8.25

Candies that are red = 2.5

Candies that are blue = 3.75

Candies that are white willbthen be:

Total pounds bought - (Red + Blue)

= 8.25 - (2.5 + 3.75)

Answers

Answer:

16 people

Step-by-step explanation:

Given that :

Number of people to tour = 80

Number per group = 16

Number of groups = 4

Total number of people who make up the entire groups :

Number per group * number of groups

16 * 4 = 64

The number of people in the last tour group :

80 - 64

= 16 people

in the model below what is x and how do I solve it​

Answers

Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.

X=6

Step-by-step explanation:

(8x-4)+(3x+17)=(17x-23)

Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.

11x+13=17x-23

Now this is what the equation should look like after combining ur alike terms.

11x+13=17x-23

-11x. -11x.

now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.

13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.

36=6x and now u just divide the 36 by 6 and remember to always divide by the x

Now the answer is x=6

PLS HELPPPPPPPPPPP​

Answers

Answer:

a = 18

Step-by-step explanation:

2(a-7)=a+4

Distribute 2 into left side: 2a -14 = a + 4

subtract a from both sides  2a-a-14 = a+4-a

Simplify: a  - 14 = 4

Add 14 to both sides: a - 14 + 14 = 4 +14

Simplify:   a = 18

If wanted, plug a into original to double check work:

plug in: 2 (18-7) = 18+4

do parenthesis first: 2 (11) = 18+4

do multiplication : 22 = 18+4

additions: 22 =22

a = 18 is correct.

Answer:

A=18

Step-by-step explanation:

2(a-7)=a+4

2a-14=a+4

add 14 to both sides

2a=a+18

subtract a from both sides

a=18
