Work out the percentage change to 2 decimal places when a price of £198 is decreased to £160.
Answer:
p ≈ 19.19 %
Step-by-step explanation:
198 - p×198/100 = 160
19800 - 198p = 16000
19800 - 16000 = 198p
3800 = 198p
p = 19.19 %
The percentage change is -19.19%.
What is percentage change?The percentage change (or) the percentage change of a quantity is the ratio of the difference in the quantity to its initial value multiplied by 100.
Given that, a price of £198 is decreased to £160.
Percentage change = (final - initial) amounts ÷ initial amount × 100
Percentage change = (160 - 198) / 198 × 100
= - 38 / 198 × 100
= - 19.19%
The negative is showing decrease.
Hence, the percentage change is - 19.19%

Seth solved a quadratic equation. His work is shown below, with Step 3 missing.
What could Seth have written as the result from Step 3?
+ (x 1)2 + 5 = 23
5(x - 1)2 = 18
Step 1
(x - 1)2 = 36
Step 2
Step 3
x = -5 or = 7
Step 4
Answer:
|x - 1| = 6
Step-by-step explanation:
After step 2, we have that:
(x - 1)^2 = 36
and after step 4, we have the results:
x = -5 or x = 7
After step 2, what we can do in step 3 is: use square root in both sides of the equation:
|x - 1| = 6
This equation can be split in two:
x - 1 = 6 -> x = 7
x - 1 = -6 -> x = -5
So Seth could write this equation in step 3:
|x - 1| = 6
The value of x from the given expression are 5 and 7
Solving expression for the variableGiven the expression
5(x - 1)^2 = 18
Step 2 as shown is given as:
(x - 1)^2 = 36
Take the square root of both sides
√(x - 1)^2 = √36
x - 1 = 6
The solutions are x - 1 = 6 and x + 1 = 6
x = 6 + 1 = 7
x = 6 - 1
x = 5
Hence the value of x from the given expression are 5 and 7

Look at the two equations:
-3x + 6 = 21
-3x + 6 <21
Which statement best describes the process used to solve the equations?
Answer:
From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that the process is exactly the same for solving the equation and solving the inequalityStep-by-step explanation:
Given that the two equations -3x + 6 = 21 and -3x + 6 <21
To find the statement best describes the process used to solve the equations :From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that
-3x+6-6=21-6
-3x=15
[tex]x=-\frac{15}{3}[/tex]
∴ x=-5-3x + 6 <21
-3x+6-6<21-6
-3x<15
[tex]x< -\frac{15}{3}[/tex]
∴ x< -5 From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that the process is exactly the same for solving the equation and solving the inequality.The first equation is a statement of equality, while the second is an inequality. The process is solving equations and inequalities.
The process used to solve the equations involves identifying whether the given expressions are equations or inequalities and then applying appropriate techniques to find the solution.
For the equation [tex]\( -3x + 6 = 21 \)[/tex], the goal is to find the value of [tex]\( x \)[/tex] that makes the equation true. We start by isolating [tex]\( x \)[/tex] on one side of the equation. By subtracting 6 from both sides and then dividing by -3, we find [tex]\( x = -5 \)[/tex]. This is the solution to the equation.
On the other hand, for the inequality [tex]\( -3x + 6 < 21 \)[/tex], the goal is to find the values of [tex]\( x \)[/tex] that satisfy the inequality. We follow similar steps as with the equation but with one crucial difference: when dividing by a negative number, the direction of the inequality sign must be reversed. After isolating [tex]\( x \)[/tex], we find [tex]\( x > -5 \)[/tex]. This represents all values of [tex]\( x \)[/tex] that make the inequality true.
In summary, the process involves understanding whether we are dealing with equations or inequalities, isolating the variable, and solving for its value. For inequalities, attention must be paid to reversing the inequality sign when dividing by a negative number.

Shanti wrote the predicted values for a data set using the line of best fit y = 2.55x – 3.15. She computed two of the residual values.
What are the values of a and b?
a = 0.4 and b = –0.15
a = –0.4 and b = 0.15
a = 8.6 and b = 14.25
a = –8.6 and b = –14.25
[tex]a=4.1-4.5=-0.4\\b=7.2-7.05=0.15[/tex]
The values of a and b are,
⇒ a = -0.4 and b = 0.15
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, Residual value is the difference between the observed value of the dependent variable (y) and the predicted value (ŷ) in a data set.
i.e. Residual value = given value - predicted value
From the table, the residual value corresponding to a has 4.1 as the given value and 4.5 as the predicted value.
Therefore, We get;
a = 4.1 - 4.5
a = -0.4
Similarly, the residual value corresponding to b has 7.2 as the given value and 7.05 as the predicted value.
Therefore, We get;
b = 7.2 - 7.05
b = 0.15
Therefore, a = -0.4 and b = 0.15

jennifer walks 8 miles in the same time she can jog 13 miles. if her jogging speed is 8mph faster than her walking speed, how fast does she walk?
Answer:
12.8mph
Step-by-step explanation:
Let 'w' represent her walking speed
->if her jogging speed is 8mph faster than her walking speed
Jogging speed= w+8
Using the time equation i.e time = dist/speed
For walking when distance is 8miles
time = dist / speed= 8/w hrs
For jogging when distance is 13miles
time = dist / speed= 13/(w+8) hrs
Equating the time
jog time = walk time
13/(w+8) = 8/w
By cross multiplying it
13w = 8w + 64
5w = 64
w=64/5
w=12.8mph
Therefore, 12.8mph is her walking speed.

dan made $242 for 11 hours of work. At the same rate , how many hours would he have to work to make $ 154
Answer: 7 hours to make $154.
Step-by-step explanation: First we want to know how much Dan makes in 1 hour of work. To do this simply divide 242 by 11. 242/11 = 22, or $22 per hour of work.
T find how many hours he would have to work to make $154, simply divide 154 by 22. 154/22 = 7, or 7 hours of work.
So, Dan will have to work 7 hours to make $154.
Final answer:
Dan earns $22 per hour, so to make $154, he would need to work for 7 hours at that same rate.
Explanation:
Dan made $242 for 11 hours of work. To calculate the rate of pay per hour, we would divide $242 by 11 hours, which gives us a rate of $22 per hour. The question asks how many hours Dan would need to work to make $154 at the same rate. To find this, we divide $154 by the hourly rate of $22.
$154 ÷ $22 per hour = 7 hours
Therefore, Dan would have to work for 7 hours to make $154 at the same rate of pay.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. Out of the two given options, 3/4 is closer to 1.
What is a number line?A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.
The value of 13/10 is equal to 1.3, while the value of 3/4 is 0.75. Therefore, the difference between the two numbers from 1 will be equal to,
[tex]D_1 = 1.3-1 = 0.3[/tex]
[tex]D_2 = 1-0.75 = 0.25[/tex]
Since the value of 0.3 is greater than 0.25, therefore, the gap between 13/10 and 1 will be more than 3/4 and 1.
Hence, out of the two given options, 3/4 is closer to 1.

We divide the number line into ___ so we know how far to move left or right when doing equations.
Answer:
units
Step-by-step explanation:
I had this question on flocabulary.
We divide the number line into intervals to understand how far we need to move left or right when solving equations. This division into intervals creates a physical representation that helps visualize calculations and absolute differences between numbers.
Explanation:We divide the number line into intervals so we know how far to move left or right when doing equations. For understanding, let's consider an example. If we're working with whole numbers and the number line is divided into single-unit intervals, moving to the right from 0 to 5 means we've added 5 to our original number. Similarly, moving to the left of 0 to -5 means we've subtracted 5 from our original number.
The division of the number line helps to visualize the calculation process and see physical representation of absolute differences between numbers. For example, if we make the distance between each interval equal to one unit, the distance between 1 and 3 on the number line is 2 units, which corresponds to the absolute difference between these numbers.
