Tavon has a gift card for $70 that loses $3 for each 30-day period it is not used. he has another gift card for $ 60 that loses $ 2.50 for each 30-day period it is not used. a. write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. b. what will the value of each card be when they have equal value?

Hello,

Your answer would be: 55

My work:

For this problem all you have to do is keeping subtracting 3 until you get a matching number in which I got 55.

Hope this helps!

Brainliest!?!

Have a great day:)

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.

i can you answer this question sweetie!
