Answer:

(3/5)x+1/4=(3/4)x-2/5

<=> (3/5)x - (3/4)x= -2/5 - 1/4

<=> x(12/20 - 15/20) = -13/20

<=> x(-3/20) = -13/20

<=> x = 13/3

90 POINTS!!!!! Given: KLIJ inscr. in k(O),m∠K = 64°, measure of arc LI = 69°, measure of arc IJ = 59°, measure of arc KJ =97°

Kay [80]

In any cyclic quadrilateral, angles opposite one another are supplementary, meaning

$m\angle K+m\angle I=m\angle L+m\angle J=180^\circ$

and given that $\boxed{m\angle K=64^\circ}$ , we have $\boxed{m\angle I=116^\circ}$ .

By the inscribed angle theorem,

$m\angle JLK=\dfrac12m\widehat{KJ}$

$m\angle ILJ=\dfrac12m\widehat{IJ}$

and since

$m\angle L=m\angle JLK+m\angle ILJ$

we have

$m\angle L=\dfrac{97^\circ+59^\circ}2\implies\boxed{m\angle L=78^\circ}$

and it follows that

$m\angle J=180^\circ-m\angle L\implies\boxed{m\angle J=102^\circ}$

Joe is making $485 payments monthly, but the amount gets interest on a yearly basis, not monthly, so the amount that yields interest is 485*12

also, keep in mind, we're assuming is compound interest, as opposed to simple interest

Xavier Martinez took out a $5,000 loan at 7.5% interest for reconstructing his patio. His monthly payment on the 12-month loan w

Norma-Jean [14]

Paying off the entire loan = 12 * 437.26 = 5,247.12 
He paid 6 * 437.26 = 2,623.56 
He then paid 2,556.03

2,623.56 plus = 2,556.03 = 5,179.59 

 5,247.12 minus 5,179.59 =
67.53 the amount of money he saved.
