A number is 1/7 another number. the difference of the number is 18. assume that you are subtracting the smaller number from the larger number. find the number

Answers

Answer:

21 and 3

Step-by-step explanation:

Let's call the small number $x$ and the larger number $y$ .

According to the problem:

$x=(1)/(7)y$

And when you substract the smaller number from the larger number you get 18:

$y-x=18$

substituting the first equation in the second one:

$y-(1)/(7)y=18(6)/(7)y=18\n y=(18*7)/(6) =3*7=21\ny=21$

the larger number is 21.

Using the first equation to find $x$ :

$x=(1)/(7)y\n x=(1)/(7) (21)\nx=3$

the smaller number is 3.

a = the smaller number
b = the larger number
a = 1/7 b
b - a = 18
b - 1/7b = 18
6/7b = 18
b = 21
a = 1/7 * 21
a = 3

Is 12 cups greater than 3 pints

Answers

yes. 1 pint = 2 cups. youd only need 6 cups to make 3 pints. therefore 12 cups would be 6 pints.

12 cups is 6 pints so therefore if 6 is greater than 3 your answer is yes.

Linda is planning to build a rectangular deck that is 12 feet longer than it is wide. Find its width if its area is 589 square feet. Write an equation that models this problem?

Answers

Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589
$x^(2) +12x = 589$
Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
