Is the number a multiple of 8? Write yes or no. 4, 8, 20, 40.WHAT IS MULTIPLE

BARSIC [14]

Consider two integers $x,y$ . We say that $x$ is a multiple of $y$ if $x$ is evenly divisible by $y$ :

$\dfrac{x}{y} = k,\quad x,y,k \in \mathbb{Z}$

Alternatively, we can say that $x$ is a multiple of $y$ if there exists an integer $k$ such that $x = ky$

So:

4 is not a multiple of 4, because 4/8 is not an integer.
8 is a multiple of 8, because 8/8=1
20 is not a multple of 8, because 20/8 is not an integer
40 is a multiple of 8, because 40/8=5

For a particular event, 771 tickets were sold for a total of $3037. If students paid $3 per ticket and non-students paid $5

BlackZzzverrR [31]

Answer:

Number of student tickets were sold = 409

Step-by-step explanation:

Total number of tickets sold = 771

I.e Students ticket (S) + Non students ticket(N S) = 771

Total amount to be paid for tickets = $ 3037

Amount paid by students per tickets = $3

Amount paid by non-students per tickets = $5

So, according to question

S + NS = 771

3 S + 5 NS = 3037

Solve both equations

5 S + 5 NS = 771 × 5

3 S + 5 NS = 3037

so ,

(5 S + 5 NS) - (3 S + 5 NS ) = 3855 - 3037

Or, 2 S = 818

I.e S = $\frac{818}{2}$ = 409

Hence, The number of student tickets were sold = 409 Answer

Is -3x+4y=8 parallel or perpendicular to -4x+3y=-6

meriva

Step-by-step explanation:

4y = 3x +8

y= 3/4x +2

3y = 4x -6

y = 4/3x -2

neither, perpendicular is negative reciprocal, and parallel m is the same. 3/4 =\ 4/3 and they are not negative reciprocals.
