Answer:

There are 18 pigs and 12 chickens.

Step-by-step explanation:

p = # of pigs

c = # of chickens

I'm assuming each animal has one head and all the pigs have 4 legs and all the chickens have 2 legs, therefore:

p+c = 30

4p+2c = 84

Elimination:

-2(p+c = 30)        -2p -2c = -60

4p +2c = 84         4p +2c = 84

                            2p    =     24

                               p    =    12

Now substitute p for 12:

12 + c = 30

c      =    18

Check:

4(12) + 2(18) = 84

48     + 36    = 84

84 = 84

There are 18 chickens and 12 pigs.

expression: -24 * 4

Integer: -96

The pool loses 96 fl oz of water after 4 minutes.

Explanation:

4x+8=32

Isolate for x. Start by subtracting 8 from both sides of the equation.

4x+8−8=32−8

4x=24

Divide both sides of the equation by 4.

4x4=244

x=6

Answer:

volume = Pi(2x^2+3x-5) x (2x+5)^2    or     P1(8x^4+52x^3+100x^2-125)

Step-by-step explanation:

radius = (4x+10)/2 = 2x+5

volume = Pi(2x^2+3x-5) x (2x+5)^2

volume = Pi(2x^2+3x-5) x (4x^2+20x+25)

volume = P1(8x^4+52x^3+100x^2-125)

Answer:

Explanation:

Remove Parenthesis: (a) = a

3x² + 4 - (-2x² + 3x + 6)

Simplify -(-2x² + 3x + 6): 2x² - 3x - 6

3x² + 4 + 2x² - 3x - 6

Simplify 3x² + 4 + 2x² - 3x - 6

5x² - 3x - 2

Apply Perfect Square Formula: (a - b)² = a² - 2ab + b²²: a = 2s, b = 7

(2s)² - 2 · 2s · 7 + 7²

Simplify (2s)² - 2 · 2s · 7 + 7²

4s² - 28s + 49

Answer:

- 62

Step-by-step explanation:

Calculate the sums within the brackets first and then multiplication, as stated by the BOMDAS rule.

B = Brackets

O = ?

M = Multiplication

D = Division

A = Addition

S = Substitution

(- 6 + 4) = -2

(5 + 9) = 14

- 2 × 14 = -28

- 28 - 3 = - 31

2 × - 31 = - 62

Answer:

4

0+0+0+5+6=7+10 = 28

28 divided by 7 is 4

To find mean you need to add up all the numbers then divided them by the total number of numbers there are. 0+0+0+5+6=7+10 has 7 numbers so I divided 28 by 7.

Step-by-step explanation:

A function rule describes how to convert an input value (x) into an output value (y) for a given function. An example of a function rule is f(x) = x^2 + 3. A function table is another name for an input-output table, a table that shows how a value changes according to a rule.

Answer: After t seconds, Fred is far away from Mark by (45-t).

Step-by-step explanation:

Given: Mark gives Fred a 45meter head start.

After t seconds, the distance of  Fred from the starting point = 5t+45

The distance of Mark from the starting point = 6t

Now, Distance between Fred and Mark after t seconds = Location of Fred - Location of Mark

= (5t+45)-6t

= 5t+45-6t

= 45-t

Hence, After t seconds, Fred is far away from Mark by (45-t).

Answer:

yes, yes, no, yes, yes (x > 0)

Step-by-step explanation:

the longest side must not be greater than the other 2 sides added up.

5 + 7 > 8 (yes)

10 + 3 > 11 (yes)

16 + 5 = 21 (no)

4 + 1.4 > 5 (yes)

3x + 4x > 5x (yes, x > 0)

Answer:

x = 5

y = 2

Step-by-step explanation:

In this question, you will have to use one of the equations to find the value of x in terms of y and substitute it in the other equation or vice versa.

y = 2x - 8

x - y = 3

Use the second equation to find the value of x in terms of y.

x - y = 3

x = y + 3

Now that we found that, we can substitute it in the other equation.

y = 2 (y + 3) - 8

y = 2y + 6 -8

y = 2y -2

y + 2 = 2y

y = 2

Now that we got y we can substitute the value in any of the equations to find x.

x - 2 = 3

x = 5

Answer:

29.) 7.2 + 3 = 10.2

30.) 15.5 + 2 = 17.5

31.) 0.8 + 11 = 11.8

32.) 8.7 + 9 = 17.7

33.) 21.8 + 6 = 27.8

34.) 1.6 + 8 = 9.6

Hope this helps!

Step-by-step explanation:

29. m-3= 7.2

1. add three on both sides

30. n-2= 15.5

1. add two on both sides

The same applies to the rest.
