Answer:
Step-by-step explanation:
Amount of water in tank 1 = amount of water in tank 2
30t +25 = -20t + 1000
Add 20t to both sides
30t + 20t + 25 = -20t + 20t + 1000
50t + 25 = 1000
Subtract 25 from both sides
50t + 25 - 25 = 1000 - 25
50t = 975
Divide both sides by 50
t = 975/50 = 39/2
t = 19 minutes 30 seconds
After 19 1/2 minutes both tanks will have 610 liters of water
7x-x=19-7
6x=12
x=2

Answer:
I have uploaded a picture so you could understand it a little more.
A linear function is when there is a table that gives numbers that represent a function, as shown in the picture.
In the Image, there is a table with a x and y column. And in both columns, there are numbers.
This is what the table looks like in the picture:
<u> x y </u>
0 4 The key is y = 2x + 4
1 6 <------ lets grab the number 1 in the x column and lets
2 8 multiply it by two. Now add four to it, and we will
3 10 have the number 6 in the y column.
4 12
I hope I helped you! God bless :-)
Answer:
6 I think
Step-by-step explanation:
7 + 5(x - 3) = 22
7 + 5x - 15 = 22
7 + 5x = 37
5x = 30
x = 6
{ 6 }
Answer:
x ≤ 22
Step-by-step explanation:
≤ means less than or equal to
≥ means greater than or equal to
