b.
- 1
d.
1
Answer:
D. x=1
Step-by-step explanation:
Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1
x = 1 for equation 5x - ( 4x - 1) = 2.
An equation is a mathematical statement that shows that two mathematical expressions are equal. It may have one variable, two, three and so on.
For given equation,
5x - ( 4x - 1) = 2
This is a equation in one variable which can be solved by transposing the terms.
Firstly, Solving the parenthesis,
5x-4x+1=2
Then, Solving the like terms.
x+1=2
To calculate the value of x, subtract 1 from both the sides.
x+1-1=2-1
x=1
Thus, the value of x is 1. So, option d) is correct.

what is opportunity sampling
Answer:
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.

Determine the rate
100 cars pass by in 2 hours
Answer:
if 100 came by in 2 hours 50 would come by in one hour
Step-by-step explanation:
split it it's by 2
If 100 came by in 2 hours then 50 would come by in one hour.
What is unit rate?There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.
We have been given 100 cars pass by in 2 hours
We need to find the unit rate.
Total car = 100
Time = 2 hours
Unit rate = 100/2
Unit rate = 50
Therefore, the unit rate of 50 car in one hour.

Find the gradient of the line segment between the points (-1,1) and (-1,4).
Answer:
The gradient of the line segment between the points (1,-1) and (3,-13) is -6
Step-by-step explanation:
The gradient of the line segment between the points (1,-1) and (3,-13) is -6
Step-by-step explanation:
We need to find the gradient of the line segment between the points (1,-1) and (3,-13)
The gradient is basically the slope of line.
The formula used to calculate slope\gradient is: Slope=\frac{y_2-y_1}{x_2-x_1}\\
We have x_1=1, y_1=-1, x_2=3, y_2=-13
Putting values and finding slope
Slope=\frac{y_2-y_1}{x_2-x_1}\\\\Slope=\frac{-13-(-1)}{3-1} \\Slope=\frac{-13+1}{2} \\Slope=\frac{-12}{2}\\Slope=-6
So, gradient of the line segment between the points (1,-1) and (3,-13) is -6

A phone company charges $67 for monthly access and $14 for each gigabyte of data used. If you sign a two-year contract and use 147.5 gigabytes of data, what is the total amount you will pay for phone service?
Answer:
the answer is below :)
Step-by-step explanation:
BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y. ($120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x to find where the gigabytes are the same.
100 + 10x = 120 + 5x
Subtract 100 from both sides: 10x = 20 + 5x
Subtract 5x from both sides: 5x = 20.
Divide both sides by 5: x = 4. 4 gigabytes is the answer.
a brainliest would be appreciated :)
The total amount you will pay for phone service is 4 gigabytes.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
BigBytes will be 100 +10x = y
Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y.
We have $120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x;
100 + 10x = 120 + 5x
Now Subtract 100 from both sides:
10x = 20 + 5x
Then Subtract 5x from both sides:
5x = 20.
Now Divide both sides by 5:
x = 4.
Hence, the total amount you will pay for phone service is 4 gigabytes.

Answer:
Step-by-step explanation:
volume = πr²h = π·3²h = 63π
h = 7 cm
The height of the given cylinder is 7 cm. Therefore, option D is the correct answer.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, the volume of a cylinder is 63π cm³ and the radius is 3 cm.
We know that, the formula to find the volume of a cylinder is πr²h.
Now, πr²h=63π
π×3²×h=63π
h= 7 cm
Therefore, option D is the correct answer.
