Answer:

The greatest number of identical packets she can make with no items left over is 23. Each packet will have 4 crayons and 1 sheet of paper.

Step-by-step explanation:

The first step is to check if exists a linear relationship between the amount of crayons and the amount of sheets of paper. We can check this by dividing one amount over the another one :

\frac{92}{23}=4 ⇒ This proportion 92 : 23 is equivalent to 4 : 1

We find that for each sheet of paper we will need 4 crayons to make all the packets identical.

Now, to see which will be the greatest number of packets we only need to look at the number of sheets of paper (because each packet will have only one sheet of paper).

The teacher has 23 sheets of paper. Therefore, she will be able to make 23 identical packets ( where each one will have 4 crayons and 1 sheet of paper).

-5x-4y=2a 4x-5y=2 which of the following choices of A will results in a system of linear equations with exactly one solution​
hjlf

Answer:

<h3>            Any of them.</h3><h2>          a ∈ R</h2>

Step-by-step explanation:

-5x - 4y = 2a                         4x - 5y = 2

-4y = 5x + 2a                        -5y = -4x + 2

y = (5x + 2a):(-4)                    y = (-4x + 2):(-5)

y = -⁵/₄x - ¹/₂a                           y = ⁴/₅x - ²/₅

m₁ = -⁵/₄,  b₁ = -¹/₂a                  m₂=⁴/₅,  b₂= -²/₅

               -⁵/₄ ≠ ⁴/₅

Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.

Work out the length of ab, give your answer to 3 significant figures
Aleksandr [31]

Answer:

D = 9.85 units

Step-by-step explanation:

A (1,7) and B(10,3)

Using Distance Formula to find the length

=> Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

=> D = \sqrt{(10-1)^2+(3-7)^2}

=> D = \sqrt{(9)^2+(-4)^2}

=> D = \sqrt{81+16}

=> D = \sqrt{97}

=> D = 9.85 units (Upto 3 sfs)
