started with 225 added 75
225 +75 = 300 then added 200
300 +200 = 500, took 50 out
500-50 = 450 then added 125
450 +125 = 575
895-575 = 320
Answer is B $320
Answer:
(11.4 - 22.8) / (26 - 7)
-11.4 / 19 this is the rate at which it burns - the slope
h = (-11.4/19)t + b
22.8 = (-11.4/19)7 + b
22.8 = (-79.8/19) + b
22.8 = -4.2 + b
27 = b
h = (-11.4/19)t + 27
Substitute 15 for t to determine the height of the candle.
Answer:
7
Step-by-step explanation:
Substitution then simplify
Answer:
(4x3-6x) + (8x-12)= 2x
(4x3+8x) + (-6x2-12)= 2(2x-3) (x^2+2)
Step-by-step explanation:
All you have to do is simplify.
