Answer:
x = 112
Step-by-step explanation:
We can create two equations 1. one that calculates calories burned and 2.another that calculates minutes:
20*x + 5*y = 1200
x + y = 120
Then we can solve for x
x = 120 - y
then we can plug that into the top equation:
20(120 - y) + 5y = 1200
divide by 5:
4(120 - y) + y = 240
distribute:
480 - 4y + y = 240
and then do all that combining like factors what not and simplify and solve:
480 - 3y = 240
-3y = -240
y = 8
NOW WE CAN JUST PLUG IN THE ANSWER FOR Y TO FIND X
8+x =120
x = 112
Answer:
y=2/7x+2.5
Step-by-step explanation:
33.3%, move the decimal to the left twice to make it easier. then multiply 29.99 by .333. take that and subtract it from 29.99. I got 20, I'm not sure if that's right though
I think you have to multiply them. If you have a calculator you can do it easily.
Answer:
Step-by-step explanation:
Let d represent the total number of days that the milk will last.
The total number of cat warriors travelling together is 8. Each cat needs 4 liters of milk per day to maintain good morale. This means that the 8 cat warriors would need
8 × 4 = 32 liters of milk.
Let n represent the total number of liters of milk available. Therefore, the total number of days the milk will last, d would be
d = n/32
Mirri has a supply of 96 liters of milk. Another cat has enough milk to last for 2 days. This means that the amount of milk that the cat has is 4 × 2 = 8 liters. Total amount of milk available would be
96 + 8 = 104 liters
Therefore
d = 104/32 = 3.25 days
