Answer: Tiffany 15mph, Maggie 20mph
Step-by-step explanation:
Set up the equation 4((x+5) + x) = 140. x+5 represents how many miles Maggie covered in one hour. x represents how much Tiffany traveled in one hour. 140 is the number of miles in total. 4 is the number of hours in total.
Simplify the equation.
(x+5) + x = 35 Divide both sides by 4
2x+5 = 35 Combine like terms
2x = 30 Subtract 5 from both sides
x = 15 Divide both sides by 2
Tiffany traveled 15mph, while Maggie traveled 15+5=20mph.
Answer:
30% probability that it will be yellow, or green
Step-by-step explanation:
The urn has red, white, blue, yellow, and green balls.
Each ball is chosen with the following probabilities:
1/10 = 10% probability it is red
2/5 = 40% probability it is white
1/5 = 20% probability it is blue.
p probability it is yellow or green
What is the probability that it will be yellow, or green
The sum of all probabilities is 100%. So
10 + 40 + 20 + p = 100
p = 30
30% probability that it will be yellow, or green

The solution of the equation which is as described in the task content when expressed in its simplest form is; -5/13.
<h3>What is the solution of the equation as described in the task content?</h3>
It follows from the task content that the solution to the equation is to be determined and expressed in its simplest form.
Given;
-1/2 -1/2(4/5x+1) = -2 -3x
By distributing the coefficients: we have;
-1/2 - 2/5x - 1/2 = -2 -3x
Hence, by collecting like terms; we have;
-1/2 - 1/2 + 2 = -3x + (2/5)x
1 = -13x/5
Therefore; by cross-multiplication; we have;
5 = -13x
Divide both sides by; -13.
x = -5/13.
Ultimately, the solution of the equation which is as described in the task content when expressed in its simplest form is; -5/13.
