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.

Write a percent problem for which the percent is greater than 100 and the part is known . Use the percent equation to solve you

KATRIN_1 [288]

A percent greater than 100 could be 150%.
Lets say part is 15
15 is 150% of what?
is/of=%/100
fill in that and cross multiply to find "of"
15/x=150/100
x should equal 10.
I'm not sure exactly what your asking but if you are supposed to just make up numbers? And solve for it? That should be what you're looking for. Good luck I guess!

Solve each system by graphing.

ValentinkaMS [17]

Answer:

no solution

Step-by-step explanation:

These lines have the same slope and different y-intercepts, so graph as parallel lines. As such, they will have no point of intersection, so there is NO SOLUTION to this system of inconsistent equations.
