John's extremely generous mother gave him $150 to spend on new school clothes. Shirts cost $15 each and a pair of pants cost $25. If John spent all $150 and bought 5 shirts, how many pairs of pants did he buy?

3 pairs of pants

Step-by-step explanation:

he can still buy 3 pairs of pants

Step-by-step explanation:  15x5=75

75 + 75 = 150

he can buy 5 shirts

and 3 pairs of pants

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.
