As an estimation we are told £3 is €4.
Convert €20 to pounds.
Answer:
£15
Step-by-step explanation:
Set up a proportion, where x is €20 in pounds
[tex]\frac{3}{4}[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x:
4x = 60
x = 15
So, €20 is equal to £15

J. Multiplication Property of Equality
K. Division Property of Equality
Answer:
Substitution property
Step-by-step explanation:
From the list of given options, the option that answers the question is
H. Substitution property
This is so because replacing a term or a value with another implies substitution, as shown when.
WV was substituted for TU in RS+TU=XY.
None of the other options A-G & I-K justify the given expression and operation.
Hence, we can conclude that the answer to the question is the Substitution property

A rectangular car park is being measured so that a fence can be constructed around it.The width of the car park is 12 m, correct to the nearest metre. The length of the car park is 34 m, correct to the nearest metre.What length of fence should be ordered to guarantee that there will be enough to surround the car park?
Answer:
92mStep-by-step explanation:
Since we are to construct the fence around the park, to determine the length of the fence, we will find the perimeter of the rectangular car park.
Perimeter of the car park = 2(Length + Width)
Given
Width of car park = 12m
Length of the car park = 34 m
Substituting the given data into the formula;
Perimeter of the park = 2(12+34)
Perimeter of the park = 2(46)
Perimeter of the park = 92m
Hence the length of fence that should be ordered to guarantee that there will be enough to surround the car park is 92m

You have $5.50 in your pocket and then you receive $5.50 for doing your chores.You have $5.50 in your pocket and then you receive $5.50 for doing your chores.
Answer:
For the first three situations, the sum is zero.
Step-by-step explanation:
As the expenses are negative of earnings, so assuming the earning amount is positive while the spending amount is negative.
Shawna spends $20 and she earns $20,
So, the sum of the total amount is
-20+20=0
A diver dove down 20.14 feet under-water and then descended 20.14 feet.
First, the diver ascends 20.14 feet then descends the same.
As the ascending and the descending are opposite to each other.
The sum of both is
+20.14-20.14=0
So, in this case, the diver has a sum of zero.
For shooting over par the golfer have +2 points while for shooting under par the golfer have -2 points,
So, the total points are
+2-2=0
So, in this case, the golfer has a sum of zero points.
In the last case, you already have $5.50 in your pocket and then you receive $5.50 for doing your chore.
This time, there is an addition of $5.50 to the money you already have.
So, the total money, after receiving the $5.50 is
$5.50+$5.50=$11
In this case, the sum of the total amount is not zero.
Hence, for the first three situations, the sum is zero.

Given (x – 1)2 = 50, select the values of x.
x = –49
x = 51
x= 1 + 5 (2
x= 1 - 5 (2
x= 1 + 5 √2
x= 1 - 5 √2
The values of x in the expression are x = 1 + √51 and x = 1 – √51.
We have,
Expanding the left side of the equation, we get:
(x – 1)2 = x2 – 2x + 1
So, we have:
x2 – 2x + 1 = 50
Subtracting 50 from both sides, we get:
x2 – 2x – 49 = 0
Now, we can use the quadratic formula to solve for x:
x = [2 ± √(22 – 4(1)(–49))] / (2)
x = [2 ± √(204)] / (2)
x = [2 ± 2√51] / (2)
x = 1 ± √51
Therefore,
The values of x are x = 1 + √51 and x = 1 – √51.

A student did an experiment to test the hypothesis that brand name paper towels soak up water better than generic paper towels. What would be the independent variable in the student's experiment?
Answer: The independent variable is the brand and the dependant variable is the amount of water you use.
Step-by-step explanation:
The Independent variable is the condition that you change in an experiment.
The dependant variable is the condition that you measure in an experiment.
The independent variable in the student's experiment is the type of paper towel used.
In an experiment, there are three types of variables:
The independent variable : the experimenter can change or manipulate this variable in order to determine its effect on the dependent variable. The dependent variable : this is the variable whose value would be determined in the experiment.The extraneous variable : this is the variable that can affect the result of the experiment but it is not researched in the experiment.In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.

what are the steps for solving -4+2x=5-(x-3)+3x
Answer:
I Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Step-by-step explanation:
Simplify
-4 + 2x = 5 + -1(x + -3) + 3x
Reorder your terms
-4 + 2x = 5 + -1(-3 + x) + 3x
-4 + 2x = 5 + (-3 * -1 + x * -1) + 3x
-4 + 2x = 5 + (3 + -1x) + 3x
Combine your like terms 5 + 3 = 8
-4 + 2x = 8 + -1x + 3x
Combineyour like terms -1x + 3x = 2x
-4 + 2x = 8 + 2x
Add -2x to each side of your equation.
-4 + 2x + -2x = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 + 0 = 8 + 2x + -2x
-4 = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 = 8 + 0
-4 = 8
Solving
-4 = 8

In Cherokee County, the fine for speeding is $17 for each mile per hour the driver is traveling over the posted speed limit. In Cherokee County, Kirk was fined $221 for speeding on a road with a posted speed limit of 30 mph miles per hour. Kirk was fined for traveling at what speed, in miles per hour?
Answer:13 miles over the speed limit
Step-by-step explanation:
Answer:
H
Step-by-step explanation:
The fine for speeding is $17 mile per hour. Thus, for speeding for a total of x miles per hour above the posted speed limit of 30 mile per hour, there will be a fine of: 17(x - 30)
X in the equation is the speed of the driver and the negative sign in the equation shows that the driver was traveling at a total speed greater than the posted speed limit (thus, x - 30 is the speed above the posted speed limit in which the driver will be fined for).
Since the driver was fined $221, the equation becomes:
17(x - 30) = 221
divide both sides by 17
x - 30 = 221/17
x - 30 = 13
x = 13 + 30
x = 43
The driver was fined for travelling at a speed of 43 miles per hour which is 13 greater than the posted speed limit.
