Assuming you're trying to find t, first you would plug in the numbers given to get 105=(700)(.05)t
next, you multiply p and r to get 105=35t
after that, you divide the 105 by 35 to get the final answer of t=3
Answer: She had 200 cards to start with
Step-by-step explanation:
Let x = the amount of cards she had initially. This means she had x cards to start with.
She gave half of the cards she had to a friend. This means she gave her friend x/2 cards. She is left with with (x-x/2) = x/2 cards.
She also gave 1/4 of the remaining cards to her brother. This means that she gave (1/4 × x/2) = x/8 cards to her brother.
Remaining number of cards will be x/2 - x/8 = (4x-x)/8 = 3x/8
She still has 75 cards left. This means
3x/8 = 75
Cross multiplying with 8, it becomes
3x = 75×8 = 600
x = 600/3 = 200
She had 200 cards to start with.
Answer:
I think it would be 55+8x. I hope this helps. :)
Step-by-step explanation:
55 gallons of water
8 gallons per minute
It would be 55 gallons (the original amount in the tank) plus 8 gallons per minute. (8x)
x = how many minutes the tank is being filled up more.
so if you were to fill up the tank another 5 minutes, the equation would be 55+8(5)
55+40
95 would be the answer.
