Answer:
Correct option: C
Step-by-step explanation:
To solve the equation m*5 - 8 = -6, we can use the following steps:
step1: sum 8 in both sides, to make m*5 be the only term in the left side.
m*5 = 2
step2: divide both sides by 5, then we will have 'm' isolated in the left side.
m = 2/5
So the operations we could use is: add 8 to each side and then divide each side by 5.
Correct option: C
If a 12 gallon tank is filled with water at rate of 1/4 of the tank in 5 seconds, then it's filled with 3 gallons per 5 seconds (because 1/4 * 12 = 3). 5/6 of the tank is as much as 5/6 * 12 = 5 = 60/6 = 10 gallons.
If 3 gallons of the tank are filled in 5 seconds, then 10 gallons will be filled in (10 ÷ 3) * 5 = 3 1/3 * 5 = 16 2/3 seconds.
Answer: It will take 0 minutes and 16 2/3 seconds to fill 5/6 of the tank.
I hope that's what you meant :)

Answer:
y = - 9, y = 3
Step-by-step explanation:
Calculate distance d using the distance formula
d =
with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (10, y)
d =
=
Given distance between points is 10, then
= 10 ( square both sides )
64 + (y + 3)² = 100 ( subtract 64 from both sides )
(y + 3)² = 36 ( take the square root of both sides )
y + 3 = ± = ± 6 ( subtract 3 from both sides )
y = - 3 ± 6 , thus
y = - 3 - 6 = - 9
y = - 3 + 6 = 3
