Answer:
0.25
Step-by-step explanation:
use desmos for this, it's very helpful :)
As we multiply the matrices on the left-hand side,we have;
x+3y=5---eq1
x+4y=6---eq2
eq1-eq2
-y=-1
y =1
Subsitution of y=1 in eq1,
x+3(1)=5
x+3=5
x=5-3
x=2
Answer:
2
Step-by-step explanation:
Given two points on the line, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7 - -3)/(3 - -2)
= (7+3)/(3+2)
= 10/5
=2
<span>First you take 3/4 of the tank (18000 gallons)
then you have to divide that by 40 to find out how many minutes it will take to get it.
the answer would be 450 minutes</span><span>i hope that thiss helps you out, have an amazing day!!</span>
200L / 10L
= 20
Since it takes 1 hour to drain 10L, and in order to get 200L you need to drain 10L 20 times, it will take you 20 hours to drain 20L of water
Answer: 20 hours
