Farmer John looks out on his farm. One pen has chickens and pigs. John counted 12 heads and 34 legs. How many of each animal did he see? EXPLAIN your reasoning. I DO WANT YOU TO EXPLAIN AND ANSWER QUICKLY PLEASE

Answers

34 legs and 12 heads

Chicken has 2 legs and Pig has 4 legs, both got one head

7 chicken heads, 7 x 2= 14 chicken legs

5 pig heads, 5 x 4= 20 pig legs

7 chicken heads + 5 pig heads = 12 heads

14 chicken legs + 20 pig legs = 34 legs

Answer: He saw 7 chickens and 5 pigs

The area of a rectangle is 5x^3+19x^2+6x-18 with length x + 3. Using synthetic division, what is the width of the rectangle?

Answers

To compute for the area of the rectangle, we multiply the dimensions so if  we need to find the width of the rectangle, we have

width = (Area)/(length)

Thus, given an area of (5x³ + 19x² + 6x - 18) and a length of (x + 3), to find the width, we have

width = (5x³ + 19x² + 6x - 18) / (x + 3)

Through the coefficients of the polynomial, we can apply synthetic division to find the quotient as shown below.

5  19  6  -18 | -3
   -15 -12  18
_____________
5   4   -6  0

Thus, the given values below the line are the coefficients of the width. So, we have the rectangle's width as (5x² + 4x - 6) units.

Answer: (5x² + 4x - 6) units

How to solve equation 2x/5+1=7?
How to solve equation x/3-4=10?

Answers

If you would like to solve the equation 2x / 5 + 1 = 7, you can do this using the following steps:

2x / 5 + 1 = 7
2x + 5 = 5 * 7
2x = 35 - 5
2x = 30
x = 15

If you would like to solve the equation x/3 - 4 = 10, you can do this using the following steps:

x/3 - 4 = 10
x/3 = 10 + 4
x/3 = 14
x = 14 * 3 = 42

Subtract. Write your answer in simplest form.

A first number plus a second number is 10. Twice the first number plus the second totals 26.

Answers

1st number = x
2nd number = y

2x + y = 26
                    -
  x + y = 10

x = 16

26 - (2 x 16) = -6

10 - 16 = -6


Number 1 is 16
Number 2 is -6
