The answer in the solution set that will make the equation true is 10
How to determine which answer in the solution set will make the equation true?The equation is given as
4p + 5 = 6p - 15
Collect the like terms in the above equation
So, we have
4p - 6p = -5 -15
Evaluate the like terms
So, we have
-2p = -20
Divide both sides by -2
So, we have
p = 10
Hence, the answer in the solution set that will make the equation true is 10

How to find the slope of the line in the picture?To calculate the slope of the line, we make use of two points on the line
The two points to use are
(0, 0) and (25, 70)
The slope of the line is then calculated as
Slope = (y2 - y1)/(x2 - x1)
So, we have
Slope = (70 -0)/(25 - 0)
Evaluate
Slope = 2.8
Note that the slope can also be regarded as the constant average rates of change or the gradient

Bailey starts playing a game on her cell phone with the battery fully charged and plays until the phone battery dies. While playing the game the charge in Bailey's battery decreases by half a percent per minute. Write a function for the percent change in the battery while Bailey is playing the gane
The linear function for the percent change in the battery while Bailey is playing the gane is:
B(t) = 100 - 0.5t, 0 ≤ t ≤ 200.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The intercept is the initial battery, of 100.The slope is of -0.5, as the battery decays by 0.5% each minute.Hence the function is:
B(t) = 100 - 0.5t.
The battery will be of 0, when:
B(t) = 0.
100 - 0.5t = 0.
t = 100/0.5.
t = 200.
Hence the function is:
B(t) = 100 - 0.5t, 0 ≤ t ≤ 200.

A sled team consists of 11 dogs and the musher. Each dog weighs 70 pounds and the musher weighs 160 pounds. What is the average weight of the sled team members?
a
68.5 pounds
b
115 pounds
c
73.5 pounds

The average weight of the sled team members is 77.5
What is an average value?Average value can be calculated by finding the sum of a set of numbers then count the total number, then divide the sum with the number of the counted values.
To calculate the average weight of the sled team members, then we know that there are 11 dogs and the musher, which implies that there are total number of 12 animals.
Then we can find the total number of the dogs as (11*70) =770 dogs, then we can add to the musher which makes the total number of (770+160)=930
Then the average weight of the sled team members is [tex]\frac{930}{12} =77.5[/tex]

Eva went to shop and bought 3 apples, 5 peaches, 8 bananas, 1 pineapple and 3 melons. what are the mean and median of her purchase?
If Eva went to a shop and bought 3 apples, 5 peaches, 8 bananas, 1 pineapple, and 3 melons, then the mean and median of her purchase are equal to 4 and 3 respectively.
Mean can be described as the most common value in a group of numbers. The mean of a certain set can be found by the ratio of the sum of the values to the number of values.
Mean = Sum total of the expressions/ Number of expressions
Sum of the values = 3 + 5 + 8 + 1 + 3 = 20
Number of values = 5
Mean = 20 / 5
Mean = 4
Median can be described as the central number in a series of numbers or a dataset.
If we arrange the given dataset in ascending order, that is from smallest to largest, then the median can be found as follows,
1 + 3 + 3 + 5 + 8
As the middle number is 3, therefore the median of the given data set is equal to 3.

what percent of 54 is 23? explained
Answer: 42.59
Step-by-step explanation:
Step 1: First, write the problem as an equation: P% = X/Y
Step 2: Here, X is 23, Y is 54, so the equation is P% = 23/54
Step 3: A percent is a ratio of a number expressed out of 100. So P% means P/100
Step 4: Substitute P/100 instead of P% in the above equation, then P% = 23/54 becomes P/100 = 23/54
Step 5: Solve for P
P/100 = 23/54
P = (23/54) * 100 = 42.59
Therefore, 23 is 42.59 percent of 54
What is the slope of the line that passes through the points (-7, -2) and
(-2,-22)? Write your answer in simplest form.
Answer:
-4
Step-by-step explanation:
Compute the slope of the line through the following points:
p_1 = (-7, -2) and p_2 = (-2, -22)
The slope of the line through (x_1, y_1) and (x_2, y_2) is:
(y_2 - y_1)/(x_2 - x_1)
Substitute (x_1, y_1) = (-7, -2) and (x_2, y_2) = (-2, -22):
= (-22 - -2)/(-2 - -7)
-(-7) = 7:
= (-22 - -2)/(-2 + 7)
-2 + 7 = 5:
= (-22 - -2)/5
-(-2) = 2:
= (-22 + 2)/5
-22 + 2 = -20:
= (-20)/5
The gcd of -20 and 5 is 5, so (-20)/5 = (5 (-4))/(5×1) = 5/5×-4 = -4:
Answer: = -4
