Original price is the jeans = Rs450
Discount = 25%
Discount amount
= 25% of 450
= 25%(450)
= 25/100 × 450
= 25/10 × 45
= 5/2 × 45
= 225/2
= Rs112.5
Price after discount
= original price - discount amount
= 450 - 112.5
= Rs337.5
write the linear equation from the given information in slope intercept form (-1,3); slope=-3
Answer:
y = -3xStep-by-step explanation:
The standard expression of equation of a line in slope-intercept form is expressed as;
y = mx+c
m is the slope
c is the intercept
Given
slope m = -3
Point (x, y) = (-1, 3)
x = -1 and y = 3
Get the intercept
To get the intercept c, we will substitute the given values into the equation above to have;
y = mx+c
3 = -3(-1)+c
3 = 3 + c
c = 3-3
c = 0
Substitute m = -3 and c = 0 into the equation above;
y = mx+c
y = -3x+0
y = -3x
Hence the required linear equation is y = -3x

Step-by-step explanation:
If Alfonso does a job in 30 hours more than Zoe, and they can do the job together in 8 hours, how long would it take Zoe to do the job alone?
Answer:
Step-by-step explanation:
Let the time it will take Alfonso be x
Let the time it will take Zoe be y
If Alfonso does a job in 30 hours more than Zoe, then;
x = 30+y...... 1
Also if they can do the job together in 8 hours, then;
x+y = 8.... 2
Substitute 1 into 2;
x+y=8
30+y+y = 8
40+2y = 8
2y = -32
y = -16
Hence X = 30-16
X = 14
y = 30+14 = 44
hence it will take Alfonso about 44hours to do the work alone
Can a number be both rational and irrational? Why or why not?
Answer:
Step-by-step explanation:
If it is irrational, it can never be rational unless it is acted upon by something else like a power.
Pi, no matter what is done to it, can never be rational. Once a number is declared as irrational, that is what it remains.

There are two types of fish in a lake. These are carp and pike.
In a netted area of the lake 120 carp and 16 pike were caught
In the whole lake it is estimated there are 34 000 fish
Zalika estimated that there are 4000 pike in the lake altogether.
How does Zalika work out this estimate.
Answer: Ratios
Step-by-step explanation:
Zalika can work out this estimate by using the ratio of carp to pike that she first caught. This is how to use the ratios:
1) 120 carp : 16 pike --> from given information
2) 136 fish : 16 pike --> add the numbers together to get total fish compared to pike
3) Multiply by 250 --> 34000 divided by 136 is 250
4) 34000 fish : 4000 pike --> 16x250=4000
12.) Find the x-intercept and y intercept of the following equation.
9x + 6y = -36
Answer:
Thevalue of x-intercept is 0
and y intercept is-6.
Step-by-step explanation:
here,9x+6y=-36
9x = -36 - 6y
x=(-36 -6y)/9
x=(-12-2y)/9.........(i)
putting value of x in question
9[(-12-2y)/9]+6y=-36
-12-2y+6y= -36
-12+4y= -36
4y=-24
y=-6
puting value of x in equation (i)
x=(-12-2y)/9
x=(-12-2×-6)/9
x=0

The perimeter of a rectangle window is 226 cm. If the length of the window is 62 cm, what is its width?
Answer:
51 cm
Step-by-step explanation:
perimeter = 2 * length + 2 * width
226 = 2 * 62 + 2 * width
226 = 124 + 2 * width
226 - 124 = 2 * width
102 = 2 * width
102/2 = width
51 = width

Answer:
1. x= -4
2. x= 18
3. x= -15
4. x = 6
Step-by-step explanation:
Use relationship of angles to create equations and solve for x
You need to pay attention to see if the sides will be equal to each other or equal to 180
first picture on top left is x = -4
second picture on top right is x = 19/2
third picture on bottom left is x = -5

D. [tex]\frac{1}{27}[/tex]
Step-by-step explanation:
[tex]3^{-3}[/tex] = [tex]\frac{1}{27}[/tex]. First you need to remove the negative exponent, to do this move the term into the denominator. [tex]\frac{3^{-3} }{1}[/tex] becomes [tex]\frac{1}{3^{3} }[/tex], then solve for [tex]3^{3}[/tex], which equals 27. So your answer is [tex]\frac{1}{27}[/tex].

Karen earns $5 by delivering newspapers each week. She saves $3 and she spends the rest. How many weeks will it take her to save enough money to buy a $35 gift card? (Use the table to help you solve the problem; you will need to copy it onto a piece of paper...)
explain your answer down below.
Answer:
Step-by-step explanation:
There is not a table to look at.
But, if she saves $3 a week. 35/3= 11.6. It'll take her 11.6 or 12 weeks to save up $35.
Answer:
12 weeks
Step-by-step explanation:
She earns $5 each week, but she only saves $3. This would mean that she saves $3 a week and with a end goal of $35, it would take 11.6 weeks, which would round up to 12.

Eighteen 2.5 gallon buckets are needed to fill a cistern with water. Find the constant of variation. Please help! Thank you!
Given:
Eighteen 2.5 gallon buckets are needed to fill a cistern with water.
To find:
The constant of variation.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
Where, k is constant of variation.
In the given problem, water in cistern (w) is directly proportional to number of buckets (n).
[tex]w\propto n[/tex]
[tex]w=2.5n[/tex] (Capacity of each bucket is 2.5 gallons)
Therefore, the constant of variation is 2.5.
Answer:
45
Step-by-step
I just did 18 * 2.5!
It a simple answer!
The quantites are inversely so that means you multiply the numbers. Like 18 * 2.5. That's how I got 45
