Answer:
x-0,6x=20
0,4x=20/:0,4
x=50
Step-by-step explanation:
The original price of the jacket will be $50.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that after a 60% reduction, a jacket sold for $20. The original cost of the jacket will be calculated as below:-
Let the unknown number be x. Form the equation and solve for the value of x.
x-0,6x=20
0,4x=20/:0,4
x=50
Therefore, the original price of the jacket will be $50.

The temperature at 9:00 AM was 42°F. The temperature dropped 9 degrees per hour for the next seven hours. What is the temperature at 4:00 PM?
Hey there! I'm happy to help!
Let's call our hours h. Here is what we have going on.
42-9h
4:00 PM is 7 hours after 9:00 AM. So, we will replace the h with 7 and evaluate.
42-9(7)
42-63=-21
Therefore, the temperature would be -21°F.

If the sum of two consecutive number is 71 and one number is x then the other number is options are x +(x+1)=71,x+(x+2)=71,x+x=71,none of these
Answer:
x + (x + 1) = 71
Step-by-step explanation:
One number is x
So, other number = x + 1
Since, the sum of two consecutive number is 71
Therefore, x + (x + 1) = 71
Answer:
x + (x + 1) = 71Step-by-step explanation:
x - some integer
then the consecutive integer would be:
x+1 or x-1 (as x is consecutive to x-1)
the sum: x + (x + 1) or (x - 1) + x
the sum is 71 so:
x + (x + 1) = 71 or (x - 1) + x = 71

Is √10 repeating, greater than, less then, or equal to five? Because 10 lies between two consecutive perfect squares (in increasing order) ______ and ______, √10 repeating is located between the square roots of these two numbers. This means √10 repeating is located between ______ and ______, so √10 repeating is less than 5.
Given:
The number is [tex]\sqrt{10}[/tex].
To find:
The correct values for each blank.
Solution:
The given number is [tex]\sqrt{10}[/tex].
We know that, 10 lies between two consecutive perfect squares 9 and 16, [tex]\sqrt{10}[/tex]. repeating is located between the square roots of these two numbers.
[tex]\sqrt{9}=3\text{ and }\sqrt{16}=4[/tex]
This means [tex]\sqrt{10}[/tex] repeating is located between 3 and 4.
So, [tex]\sqrt{10}[/tex] repeating is less than 5.
Therefore, Blank-1=9, Blank-2=16, Blank-3=3 and Blank-4=4.

if 5x+3y=41 and x+y=11, then the value y-x is
Answer:
[tex]y-x=3[/tex]
Step-by-step explanation:
Subtract y from both sides of the equation.
[tex]x = 11-y[/tex]
[tex]5x+3y=41[/tex]
Replace all occurrences of x in [tex]5x+3y=41[/tex] with 11 -y
[tex]x=11-y[/tex]
[tex]5(11-y)+3y=41[/tex]
simplify [tex]5(11-y)+3y=41[/tex]
[tex]x=11-y[/tex]
[tex]55-5y+3y=41[/tex]
add -5y and 3y
[tex]x= 11-y[/tex]
[tex]55- 2y=41[/tex]
Solve for y in the second equation.
Move all terms not containing y to the right side of the equation.
[tex]x=11-y[/tex]
[tex]-2y=-14[/tex]
Divide each term by − 2 and simplify.
[tex]x=11-y[/tex]
[tex]y=7[/tex]
Replace all occurrences of y in x
[tex]x=11-(7)[/tex]
[tex]y=7[/tex]
simplify.
[tex]x=4[/tex]
[tex]y=7[/tex]
Replace the variable x with 4 in the expression.
[tex]y-(4)[/tex]
Replace the variable y with 7 in the expression.
[tex](7) - (4)[/tex]
Multiply − 1 by 4 .
[tex]7-4[/tex]
Subtract 4 from 7 .
[tex]3[/tex]
Answer:y-x=3
Step-by-step explanation: substitution method
5x+3y=41........ equation 1
x+y=11 .........equation 2
Since we are given two different equations in terms of two different linear equations, let us try to solve them using the concept of method of substitution:
we find that y=11-x
we will substitue y into equation 1
5x+3(11-x) = 41
5x+33-3x=41
5x-3x=41-33
2x=8
2x/2=8/2
x=4
x+y=11
then you substitute
4+y=11
y=11-4
y=7
y-x
7-4=3
