If the other number is x, then the first can be expressed as 2x-14. Then the sum of the numbers is
x + 2x - 14 = 67
3x - 14 = 67
3x = 81
x = 27
2x - 14 = 40
The numbers are 27 and 40.

-We need to start by first declaring variables to our numbers. We will use 'a' for the first number and 'b' for the second number.

-These are what the equations would look like because of what was said in the description.


a + b = 67

a = 2b - 14


now we can substitute 'a' into the first equation since it is given to us.

(2b - 14) + b = 67

-Now we can simplify until we get 'b' alone

3b - 14 = 67

3b = 81

b = 27

-Now, substitute 'b' into the first equation and simplify until 'a' is alone.

a + 27 = 67

a = 40

-To check this we can substitute our answers into the second equation since we already know it works on the first one.

(40) = 2(27) - 14

40 = 54 - 14

40 = 40

-So in conclusion your answers would be:

First number (a) = 40

Second number (b) = 27

Find the value of the variable if P is between J &amp; K. <br><br> JP = 2x ; PK = 7x ; JK = 27
Nana76 [90]
J ---- P --- K

JP = 2x
PK = 7x
JK = 27

2x + 7x = 27
9x = 27
x = 27/9
x = 3

The value of P is 3.

JP = 2x = 2(3) = 6
PK = 7x = 7(3) = 21

Fred and Sue want to fence in a rectangular area in their yard for a vegetable garden. Suppose that they have 30 feet of fencing
larisa [96]

Answer:

a=35x−x^2

Step-by-step explanation:

Having  

70 ft of fencing with a  

width of x

feet and knowing the perimeter of a rectangle is  

p=2w+2l

we can state the length of the garden as:

70=2x+2l

and solving for  l

we know the length with be:

2l=70−2x or l=35−x  

And then knowing the formula for the area of a rectangle is  

a=w⋅l

we can write the equation as:

a=x⋅(35−x)a=35x−x^2
