Elena walked 20 minutes more than Lin. Jada walked twice as long as Elena. Jada walked for 90 minutes. The equation 2(x + 20) = 90 describes this situation. Match each amount in the story with the expression that represents it

ANSWER BELOW

Step-by-step explanation:

2(X+20)=90

X+20= 90/2

X+20=45

X= -20+45

x=25

^ Lin walks 25 minutes, representing "x".

in the expression (x+20)= The amount Elena walks cause she walks 20 more minutes than Lin.

Therefore Elena walks for (25+20)=45 minutes . (i subsituted  25 for x)

this part -> (x+20) = represents the amount elena walks.

Jada walks 2 times as much as elena= therefore

2(25+20)=90 minutes

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
