Step-by-step explanation:
P(black or yellow) = P(black) + P(yellow) − P(black and yellow)
P(black or yellow) = 1/25 + 1/5 − 0
P(black or yellow) = 6/25
On 6/25 divide 6 by 25=.24 and 2 3/4= 2.75 you have 2 and then 3/4=.75
Answer:
Option A. 
Step-by-step explanation:
step 1
Find the area of the brownie pan
The area of the trapezoid is equal to

step 2
To calculate the number of days, divide the total area of the brownie pan by 30 square centimeters of brownie
so

f(x) + g(x) = 5x - 3 - 2x + 7
= 3x + 4
