1/2 = 3/6
5 gallons of water changed it to 5/6, so that would mean 2/6 would be 5 gallons worth.
5 x 3 = 15.
Hope this helps.
We have y - 2 = m(x + 5), where m = (-1 - 2)/(10 + 5) = -3/15 = -1/5;
Then y - 2 = (-1/5)(x + 5);
5y - 10 = (-1)(x + 5);
5y - 10 = -x - 5;
x + 5y - 5 = 0 is the equation of the line.
Answer: 2
The equivalent ratios are 1:2 and 5:10
Step-by-step explanation:
Let the number of days needed be x.
First day = 4 miles = 3.5 + 0.5
Second day = 3.5 + 0.5(2)
Third day = 3.5 + 0.5(3)
Equation: 3.5 + 0.5x
<u>Find the number of days needed to run 8 miles:</u>
3.5 + 0.5x = 8
0.5x = 4.5
x = 9
Answer: Casandra 8 miles on the <u>9th day</u>.
