Find the inverse for 43 modulo 660

Tatiana [17]

We're looking for $x$ such that

$43x\equiv1\mod{660}$

so for some integer $n$ we can write

$43x+660n=1$

Apply Euclid's algorithm:

$660=43(15)+15$
$43=15(2)+13$
$15=13(1)+2$
$13=2(6)+1$
$\implies(660,43)=(43,15)=(15,13)=(13,2)=1$

From this we have

$1=13-2(6)$
$\implies1=-6(15)+7(13)$
$\implies1=-20(15)+7(43)$
$\implies1=-20(660)+307(43)$
$\implies(-20(660)+307(43))\equiv307(43)\equiv1\mod{660}$

which means 307 is the inverse of 43 modulo 660.

I need this answered quick. What sum is represented by the following number line?

lianna [129]

Answer:

2 $\frac{3}{4} + -4\frac{1}{4} = -1\frac{2}{4}$

Step-by-step explanation:

The initial position of the blue line is 2 and 3/4. The final position (represented by the red line) is -1 and 1/2. 2 and 3/4 - 4 and 1/4 is the only thing you can subtract to get -1 and 2/4.

What's the constant of y=2x+5

mestny [16]

5 would have to be the constant, because in algebraic terms, a constant is a term that contains only numbers and no variables, which would knock 2x right out of the question. Hope I helped.
