Find the smallest number that divides by 44 55 and 220 leaving remainder 5
galina1969 [7]
The numbers from which we are to determine the smallest number that can be divided leaving a remainder of 5 are 44, 55, and 220. We have to do the prime factorization of all the numbers to determine their least common multiple (LCM).

Factorization of 44:
   44 = 11 x 4 = 11 x 2 x 2

Factorization of 55:
  55 = 11 x 5

Factorization of 220:
  220 = 11 x 20 = 11 x 5 x 4

Since 220 has all the factors from 55 and 44 then, the least common multiple is 220. Add 5 to the LCM in order to determine the unknown.

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

HELPPP QUICKKK PLSSSS PEOPLE I NEED HELP NOW PLSSSSS Which of the following equations describes the line shown below? Check all
Sav [38]

Let there exists a point (x, y) on the given line.

Slope of all points must be same, as they lie on the same line.

=> (y - 1)/(x - 2) = (4 - 1)/(-4 - 2)

=> (y - 1)/(x - 2) = - 1/2

=> y - 1 = (-½) (x - 2)

Option 1 is the correct option
