What value of p makes the equation true?
2 answers:
Answer:
The value of p is -20
Step-by-step explanation:
From the question in the figure above;
+
= 0
we will have to make p subject of the formula
To do that, lets re-arrange the equation
+
= 0
This equation can be rearrange to become;
= 0
Now, multiply both-side of the equation by 5. This will help us get rid of the 5 on the left hand side of the equation.
The equation becomes;
3p + 40 - p = 0
3p - p + 40 = 0
2p + 40 = 0
subtract both-side of the equation by 40
2p + 40 -40 = 0 -40
2p = -40
Divide both-side of the equation by 2
On the left hand side of the equation, the 2 in the numerator will cance that of the denominator
p =
p = - 20
Therefore p =-20 makes the equation true

SOLUTION:
Step 1:
In this question, we are given the following:
Step 2:
The details of the solution are as follows:
Step-by-step explanation:
Given :
At the state fair, admission at the gate is $9.
In addition, the cost of each ride is $3.
Suppose that Sam will go on x rides.
Then, cost of x rides ( in dollars) = Cost per ride x Number of rides
=3x
Total cost ( in dollars) : Admission fee + cost of x rides
= 9+3x
Sam wants the total number of dollars he spends on admission and rides to be at most t ( less than or equal to t )
CONCLUSION:
The final answer is:
Using the values and variables given, write an inequality describing this.
