The two equations from the previous activity are given below. k = 500 - a
3k + 10a = 3,600 (2)

Now use the substitution method to solve the modified system of linear equations. Solve the system to find the number of kids and adults who visited the carnival.

3 (500-a)+10 (a)=7200

1500-3a+10(a)=7200

1500+7a=7200

7a=7200-1500

7÷(7a=5700)

a=814.2

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

1/3 + 1/5 = 8/15.
