Perimeter of rectangle = 26
Length is 7 less than 9 times the width.
We have to find the width of rectangle[tex].[/tex]
_________________________________
Let, width of rectangle be x therefore length of rectangle will be (9x - 7)
We know that, perimeter of rectangle is given by
perimeter = 2 (length + width)⇒ perimeter = 2 (l + b)
⇒ 26 = 2 [(9x - 7) + x]
⇒ 13 = x + 9x - 7
⇒ 20 = 10x
⇒ x = 2 (width)
Cheers!Step-by-step explanation:
Let breadth be x
As it is given that, the Length is 7 less than 9 times :
Therefore, Length will be 9x - 7
Perimeter of reactangle = 26
➳ 2 ( Length + Breadth) = 26
➳ 9x - 7 + x = 26/2
➳ 10x = 13 + 7
➳ 10x = 20
➳ x = 2
Therefore,
Breadth = x = 2 Length = 9x - 7 = 9(2) - 7 = 11Related Questions

First, let's multiply the top and bottom by 9 to get rid of the fraction in the denominator.
27 / 4 is the final answer.
Answer:
31/9
Step-by-step explanation:
3 4/9 as an improper fraction is 31/9.
We get our answer by multiplying the denominator of the mixed numbers by its whole number and adding that answer to its numerator. We get 31, and we put that over the denominator.
3 4/9
9x3=27

When Joseph first starts working at a grocery store, his hourly rate is $10. For each year he works at the grocery store, his hourly rate increases by $0.50. Joseph's hourly rate R, in dollars, is a function of t, the number of years he works at the grocery store. Write the function's formula.
Answers
Answer:
R(t)=10+0.50t
Step-by-step explanation:
His rate is based on time, for the first side of the equation.
His beginning pay would be 10, so 10 would act as the y intercept. The rate increases by 0.50, so for every year (t) it would increase by 0.50, why you add 0.50 and multiply by the amount of years he works.

1/3 (6y - 9) = -2y + 13
Answers
Answer: 3,75 ( 15/4)
Step-by-step explanation:
1/3 (6y - 9) = -2y + 13
6y/3 - 9/3 = - 2y + 13
2y - 2 = - 2y + 13
2y + 2y = 13 + 2
4y = 15
y = 15/4

The more time that I spend reading, the more pages I have read. Which variable is independent?
Answers
Answer:
The more time i spend reading
Step-by-step explanation:
The variable which causes a change to the variable which we intend to measure in an experiment is the independent variable, Hence, the independent variable is the amount of time spent reading.
The Independent variable in an experiment is also called the explanatory variable, which is used to tweak the value obtained for the dependent or measured variable.
In the scenario described, the measured variable is the number of book pages read which is determined by the number of time spent reading (independent variable.)

6-x=5x+30 know the answer?
Answers
Answer:x=-4
Step-by-step explanation:
move 5x to the other side by cancelling it out with -5x
that causes it to be 6-6x=30
move 6 to other side by cancelling out with -6
causes it to be -6x=24
divide by -6 to get x alone
x=24/-6
answer is -4 when reduced
The solution to the equation 6 - x = 5x + 30 is x = -4.
To solve the equation 6 - x = 5x + 30, follow these steps:
Start by combining like terms on each side of the equation:
6 - x = 5x + 30
Rearranging the equation:
6 - 30 = 5x + x
-24 = 6x
Divide both sides of the equation by 6 to isolate the variable x:
-24/6 = 6x/6
-4 = x

Answers
Answer:
a = 1Step-by-step explanation:
equation given: a - 2(4 - a) = 7a - 12
distribute and expand the equation
a - 8 + 2a = 7a - 12
combine similar terms:
a + 2a - 7a = -12 + 8
simplify:
-4a = -4
a = -4 / -4
a = 1proof that a = 1
a - 2(4 - a) = 7a - 12
1 - 2(4 - 1) = 7(1) - 12
1 - 2(3) = 7 - 12
1 - 6 = -5
-5 = -5 therefore, the a = 1 is correct.
Steps to solve:
a - 2(4 - a) = 7a - 12
~Distribute left side
a - 8 - 2a = 7a - 12
~Combine like terms on the left side
-a - 8 = 7a - 12
~Add 8 to both sides
-a = 7a - 4
~Subtract 7a to both sides
-8a = -4
~Divide -8 to both sides
a = 1/2
