Carmela sms on her oven which heats up a 80 degrees per minute. The temperature of her house, and therefore her oven, is 70 degrees. Let x be the number of minutes that I will take for ter oven to reach 390 degrees.
which equation could be used to solve for the number of minutes?

○ 80x + 70 = 390

○ 80x - 70 = 390

○ 70x - 80 = 390

○ 70x + 80 = 390

80x - 70 = 390

Step-by-step explanation:

80/minute, starts at 70, Question: How many minutes will it take her oven to reach 390 degrees?

1.  70+80= 150

2. 150+80= 230

3. 230+80= 310

4. 310+80= 390  

It will take 4 minutes for her oven to get to 390 degrees.

○80x - 70 = 390

Hope this helped you, have a good day bro cya)

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.
