Answer:
4 and 19
Step-by-step explanation:
One number : 4x+3 (this is 3 more than 4 times x)
Another number: x This is tricky because the main number for comparison is "another number", which is x
Sum of the #s is 23: Means add them and = 23, so
x+(4x+3) = 23
5x+3=23
5x=20
x=4 and the other # is 4x+3, so 4(3)+3=19
Answer:
<em>Both buckets will have the same amount of water after 25 minutes</em>
Step-by-step explanation:
<u>Equations</u>
Let's call:
t = number of minutes elapsed for both buckets
The red bucket already has 200 L of water and it's flowing in at a rate of 6 liters per minute. Thus, the volume of water in this bucket is:
R = 200 + 6t
The blue bucket has 500 liters of water and is being drained at 6 liters per minute. The volume can be modeled by the equation:
B = 500 - 6t
The condition for both buckets to have the same amount of water is:
R = B
200 + 6t = 500 - 6t
Adding 6t and subtracting 200:
6t + 6t = 500 - 200
12t = 300
t = 300/12
t = 25 minutes
Both buckets will have the same amount of water after 25 minutes
Answer:
yellow i think
Step-by-step explanation:
68 is rounded to 70. 29 is rounded to 30. This leaves you with 70 - 30, which equals 40. Which is letter D.
