For what value of x does f(x) = g(x) when f(x) = 4x - 10 and g(x) = 0.5x + 7.5
sladkih [1.3K]

Answer:x=5

Step-by-step explanation:

4x - 10 = 0.5x + 7.5

-0.5x       -0.5x

3.5x - 10 = 7.5

       +10    +10

3.5x = 17.5

divide both sides by 3.5 and you get x=5

5 A swimming pool is being filled using a pípe A at x gallons per hour. After two hours, pipe B is used
Tpy6a [65]

Answer:

Example 1:

A tank can be filled by pipe A in 3 hours and by pipe B in 5 hours. When the tank is full, it can be drained by pipe C in 4 hours. if the tank is initially empty and all three pipes are open, how many hours will it take to fill up the tank?

Solution:

Step 1: Assign variables:

Let x = time taken to fill up the tank

Step 2: Use the formula:

Since pipe C drains the water it is subtracted.

1/3+1/5-1/4=1/x

Step 3: Solve the equation

The LCM of 3, 4 and 5 is 60

Multiply both sides with 60

solve the eqn

Answer: The time taken to fill the tank is 3 9/17 hours.

 

 

Work Problem: Pumps draining a tank

Example:

A swimming pool can be emptied in 6 hours using a 10-horsepower pump along with a 6-horsepower pump. The 6-horsepower pump requires 5 hours more than the 10-horsepower pump to empty the pool when working by itself.

How long will it take to empty the pool using just the 10-horsepower pump?

HELP 6th GRADE MATH
wlad13 [49]

Answer: What is the formula for finding the area of a triangle?

Not technically, but sometimes you may have to find the height using the Pythagorean Theorem, so if you have the hypotenuse and the base of a right triangle, the height, h = √(c^2 - b^2), so the area of the triangle could be found by A = 1/2 b √(c^2 - b^2), but it is the same principle as A = 1/2 b h.
