52s + 30b because 52 x s + 30 x b = 52s + 30b
Answer:
He can purchase 300 white baloons.
Step-by-step explanation:
150$ is 15000 cents
15000 = 60b + 30w
b being number of blue baloons,w number of white baloons and 60 and 30 prices in cents
15000 = 60*100 + 30w
15000 - 60*100 = 30w
15000- 6000 = 30w
30w = 9000
w =300
number of white baloons is 300
Answer: t = 3seconds
Step-by-step explanation:
To find the zero means we will equate the function to zero and then solve, that is
+ 32t + 48 = 0
by factorizing , we have
(t+1)(-16t+48) = 0
Therefore:
t = -1 or t = 3
since time can not be negative , then , t = 3 seconds
