The distance travelled by the runner running at a rate of 12 mph for 15 min is 3 miles.
Speed is the ratio of distance travelled to time taken. Speed is given by:
Speed = distance/time
Given that the runner is running at a rate of 12 mph for 15 min, hence:
speed = 12 mph, time = 15 min * 1/60 min per hour = 0.25 hours.
Hence:
Speed = distance/time
12 mph = distance/0.25 hours
distance = 3 miles
The distance travelled by the runner running at a rate of 12 mph for 15 min is 3 miles.

Find the discriminant and determine the number of real roots for each equation. Show steps.
-3p^2 - 2p = 0
Answer:
discriminant: 4; number of real roots: 2
Step-by-step explanation:
The coefficients a, b and c of this quadratic are {-3, -2, 0}.
Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.
Because the discriminant is positive, this quadratic has two real, unequal roots.
-3p^2 - 2p can be factored as follows: -p(3p + 2). If we set this expression equal to zero, we can find the roots: {-2/3, 0}

Two trains train a interim be weird total of 333 tons. Train hey is heavier than train B.The difference of their weight is 141 tons… What is the weight of each train??
Answer:
Weight of Train A = A = 237 tons
Weight of Train B = B = 96 tons
Step-by-step explanation:
Two trains train a and be weigh a total of 333 tons. Train A is heavier than train B.The difference of their weight is 141 tons… What is the weight of each train??
Let us represent:
Weight of Train A = A
Weight of Train B = B
Our system of Equations is given as:
A + B = 333 tons..... Equation 1
A - B = 141 tons....... Equation 2
We solve using Elimination method
We Add Equation 1 and 2 together to Eliminate B
Hence:
2A = 474 tons
A = 474 tons/2
A = 237 tons
Solving for B using Equation 1
A + B = 333 tons..... Equation 1
237 tons + B = 333 tons
B = 333 tons - 237 tons
B = 96 tons
Therefore:
Weight of Train A = A = 237 tons
Weight of Train B = B = 96 tons

What could you do to the equation 100x + 300 = 500 to change it into x + 3 = 5?
Answer:
2+3=5
Step-by-step explanation:
100x + 300 = 500
100x = 500 - 300
100× = 200
100x/100 = 200/100
therefore ^x = 2
x + 3 = 5
2 + 3 = 5
The equation 100x+300=500 is equal to the equation x+3=5.
Given that,
The equation is 100x+300=500
We have to get the equation x+3=5 from the given equation.
What is the equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. In any mathematical equation, we have LHS = RHS (left hand side equals right hand side).
We can solve in 2 methods.
1st method,
Taking the equation
100x+300=500
Divide the equation by 100
100x/100+300/100=500/100
We get
x+3=5
2nd method,
Taking the equation
100x+300=500
Taking 300 to right side
100x=500-300
Subtracting the 500 and 300
100x=200
Taking 100 to right side
x=200/100
Dividing the 200 by 100
x=2
Now,
x+3=5
Taking x to right side
x=5-3
Subtracting 5 and 3
x=2
Therefore, the equation 100x+300=500 is equal to the equation x+3=5.
