2 + 97 = 99

3 + 96 = 99

4 + 95 = 99

5 + 94 = 99

6 + 93 = 99

7 + 92 = 99

8 + 91 = 99

9 + 90 = 99

Answer:

$s = 54m +160$

Step-by-step explanation:

Given: The attachment

Required: Determine the equation

We start by picking any two equivalent points on the table:

$(m_1,s_1) = (2,268)$

$(m_2,s_2) = (4,376)$

Next, we determine the slope, M:

$M = \frac{s_2 - s_1}{m_2 - m_1}$

$M = \frac{376 - 268}{4-2}$

$M = \frac{108}{2}$

$M = 54$

The equation is then calculated as:

$s - s_1 = M(m - m_1)$

Where:

$M = 54$

$(m_1,s_1) = (2,268)$

So, we have:

$s - 268 = 54(m - 2)$

Open bracket

$s - 268 = 54m - 108$

Collect like terms

$s = 54m - 108 + 268$

$s = 54m +160$

Hence, the equation is: $s = 54m +160$

A pet store employee counts 23 heads and 68 feet on the animals in the store. The store currently only has kittens and parakeets

Aloiza [94]

Answer:

11 kittens and 12 parakeets

Step-by-step explanation:

each kitten has 4 feet while each parakeet has 2

11 x 4 = 44 (kittens)

12 x 2 = 24 (parakeets)

11 + 12 is 23 which is your 23 heads.

44 + 24 is 68 which would be your feet
