If DE= GF, HJ= 3x+20 and JI= 15x-64, find JI

Please help me! I’m really stuck on what to do

41

Step-by-step explanation:

Step 1:

Given DE = GF,

HJ = 3x + 20

JI = 15x - 64

Step 2 :

When 2 chords of a circle are same in length, then their distance from the center will be equal.

JI and HJ are the chord's length from the center because they are the perpendicular lines which joins the circle's center to the chord.

Hence we have, HJ = JI

=>  3x + 20 = 15 x - 64

=> 12 x = 84 => x = 7

To find JI, substitute the value we got for x in the expression for JI

Therefore JI = 15x - 64 = 15 * 7 - 64 = 41

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
