Tony Owens a special pet store that sells only snacks and elephants currently he has a total of 11 snacks and elephants in stock
bagirrra123 [75]

Answer:  There are 8 snake and 3 elephants.

Step-by-step explanation:

Let x= Number of snakes

y= Number of elephants

We know that , snake has no legs elephant has 4 legs.

Then, Total animals = x+y=11  (i)

Total legs = 4y = 12

⇒ y=3   .. (ii)[divide both sides by 4]

Substitute value of y from (ii) in (i) , we get

x+3=11\Rightarrow\ x=8

Hence, there are 8 snake and 3 elephants.

How is |3+10| = |3| + |10| equal
Morgarella [4.7K]

Answer:

First we must figure out what the question means. It is asking how the absolute value of 3+10 is equivalent to the absolute value of 3 plus the absolute value of ten.

Next we should solve the expressions: The absolute value of 3 plus 10 is 13. The absolute value of 3 plus the absolute value of 10 is 13. 13 and 13 are the same number.

Therefore, the expressions are equivalent.  Thus, having your answer.

15. A rectangle has a length of 2x - 1 and a width of 3x + 7. Find the perimeter of this rectangle.
andrew11 [14]

Answer:

10x + 12 and 6x² + 11x - 7

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is length and w is width )

   = 2(2x - 1) + 2(3x + 7) ← distribute parenthesis

    = 4x - 2 + 6x + 14 ← collect like terms

     = 10x + 12

--------------------------------------------------

The area (A) of a rectangle is calculated as

A = lw

   = (2x - 1)(3x + 7) ← expand using FOIL

    = 6x² + 14x - 3x - 7 ← collect like terms

    = 6x² + 11x - 7
