decrease £220 by 15%
If we decrease £220 by 15% then it would be £187
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
To find the percent of a number:x percent of number p is,
x% of p = p × (x/100)
For given example,
We need to decrease £220 by 15%
First we find the 15 percent of £220
15 percent of £220 is,
⇒15% of £220 = 220 × (15/100)
⇒15% of £220 = 220 × 0.15
⇒15% of £220 = £33
Now, we decrease £220 by 15%,
£220 - £33 = £187
Therefore, if we decrease £220 by 15% then it would be £187

Answer:
5x+3
Step-by-step explanation:
Answer:
5x + 3 = y
Step-by-step explanation:
y represents the answer
3 more means +3
Product is the answer when two or more values are multiplied together.
So, three more than the product of 5 and x would be 5x + 3 = y
Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weighs 4 kg. The total weight of Carl's baggage is 35kg
Write an equation to determine the weight, w, of each of Carl's checked bags.
And the weight of each of Carl's check bags
Answer:
(35 - 4)/2 = w and 15.5kg
Step-by-step explanation:
To get the weight of both bags you would have to first subtract the backpack's weight from the total weight. 35 - 4 = 31. Now divide by 2 to get the weight of one bag. 31/2 = 15.5. Each bag weighs 15.5 kg

Describe all numbers x that are at a distance of 4 from the number 9. Express this using absolute value notation.
Answer:
|x - 9| = 4
Step-by-step explanation:
All numbers x that are at a distance of 4 fro the number 9
Given two numbers a and B, the absolute distance between them is written as :
|a - b| = c
Hence all numbers x at distance of x from 9
|x - 9| = 4
{x : |x - 9| = 4}
Ellen has a coupon for 1.55 off a loaf of bread. The regular price of bread is 4.63. The loaf is cut into 14 slices. What is the price per slice if Ellen uses her coupon?
Answer:
0.22 or 22 cents
Step-by-step explanation:
4.63 (original bread price) - 1.55 (coupon) = 3.08
divided by 14 slices of bread is 22 cents
Answer:
$0.22 per slice
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS

Apply the coupon to the loaf of bread first. $1.55 off a loaf of bread means subtracting this amount from the original price of bread.
$4.63 - $1.55 = $3.08If the loaf is cut into 14 slices, we should divide the loaf of bread's new price by 14.
$3.08 / 14 = $0.22The price per slice if Ellen uses her coupon is $0.22 per slice.

What is a formula that can be used to find the area of one triangular section of the door how do you know the formula will work?
Answer:
[tex]Area = \frac{1}{2} L B[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
Determine the formula of one of the triangular sections
From the attachment, we have that:
[tex]L = Length[/tex]
[tex]B = Height[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} * L * B[/tex]
[tex]Area = \frac{1}{2} L B[/tex]
How to know the formula works?
From the attachment, we can see that the rectangle is divided into two equal triangular sections.
The area of the rectangle is:
[tex]Area = L* B[/tex]
[tex]Area = LB[/tex]
Because the rectangle is divided into two equal triangular sections.
This implies that, the area of one of the triangular sections is half the area of the rectangle.
So:
[tex]Area(Triangle) = \frac{1}{2}Area(Rectangle)[/tex]
Substitute LB for the area of the rectangle
[tex]Area(Triangle) = \frac{1}{2}LB[/tex]
By comparison:
[tex]Area(Triangle) = \frac{1}{2}LB[/tex] and [tex]Area = \frac{1}{2} L B[/tex] are the same
write down an expression for the nth term of the following sequence
5, 11, 17, 23, ...
Answer:
[tex]a_{n}[/tex] = 6n - 1
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence
d = 11 - 5 = 17 - 11 = 23 - 17 = 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 6 , then
[tex]a_{n}[/tex] = 5 + 6(n - 1) = 5 + 6n - 6 = 6n - 1

What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
In the middle school band, there is 1 oboe for every 7 clarinets.
Here, The ratio of the oboes to the clarinets is,
⇒ 1 : 7
Hence, Three three equivalent ratios to compare the oboes to the clarinets are,
⇒ 1 : 7
⇒ 1 / 7
⇒ 1×2 / 7×2
⇒ 2 / 14
And, 1 : 7
⇒ 1×3 / 7×3
⇒ 3 / 21
And, 1 : 7
⇒ 1×4 / 7×4
⇒ 4 / 28

Step-by-step explanation:
Jack and Jane are married and both work. However, due to their responsibilities at home, they have decided that they do not want to work over 65 hours per week combined. Jane is paid $14 per hour at her job, and Jack is paid $10 per hour at his. Neither of them are paid extra for overtime, but they are allowed to determine the number of hours per week that they wish to work. If they need to make a minimum of $850 per week before taxes, what is the maximum amount of hours that Jack can work per week according to these limits?
By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation , we find that y=20 hours, which is Jack's maximum working hours.

A.-22
B.2
C.22
D.134
Answer:
A
Step-by-step explanation:
-3(x-p)2+g=0
-3x2+12x=10
-3(x2-4x)=10
-3(x2-4x+4)=10+12
x2-4x+4 = (x-2)2
-3(x-2)2=22
-3(x-2)2-22=0
q = -22
willie has 4 treasure chests which have a combined weight of 240 pounds. If each chest weighs at least 20 pounds what is the heaviest possible weight of one of the chests?
A. 177
B. 180
C. 217
D. 234
Answer:
B. 180
Step-by-step explanation:
There is a condition that each chest needs to be at least 20 pounds and we can use that to our advantage. Because we want one of the boxes to be really heavy, we need the other three to be really light. Let's set the heavy box as variable y. Set each of the other three boxes equal to 20. Because the combined weight is 240, then the equation so far is 240 = (20*3)+y.
Now, we can solve for y. 240-60 = 180, so the heaviest box has to be 180 lb.
a cinema has three screens last saturday there were 500 visitors
Answer:
200 visitors went to screen 1.
125 visitors went to screen 2.
175 visitors went to screen 3.
Step-by-step explanation:
We will find number of visitors who went to screen 1 by finding 40% of 500 as we are told that 40% of 500 visitors went to screen 1.
Therefore, 200 visitors went to screen 1.
Now we will find number of visitors who went to screen 2. We are told that 25% of 500 visitors went to screen 2.
Therefore, 125 visitors went to screen 2.
Now we will find the number of visitors who went to screen 3 by subtracting combined number of visitors who went to screen 1 and screen 2 from total number of visitors.
Therefore, 175 visitors went to screen 3.
