Answer:

1) 4(x-7)=32

2) \frac{1}{3}x=x-12

3) 10+\frac{x}{2}=-15

4) (3x)-1=5+x

Step-by-step explanation:

Given : Expressions in words.

To find : The expressions value?

Solution :

Let x be the number,

According to question,

1) "Four times the difference of a number and 7 is 32"

\Rightarrow 4(x-7)=32

2) "One third of a number is 12 less than the number itself"

\Rightarrow \frac{1}{3}x=x-12

3) "Ten increased by the quotient of a number and 2 is -15"

\Rightarrow 10+\frac{x}{2}=-15

4) "One less than the product of a number and 3 is 5 more than the number itself"

\Rightarrow (3x)-1=5+x

<u>Part 1)</u> "Four times the difference of a number and 7 is 32"

Let

x--------> the number

we know that

the expressions is equal to

4(x-7)=32

therefore

<u>the answer part 1) is</u>

4(x-7)=32

<u>Part 2)</u> "One third of a number is 12 less than the number itself"

Let

x--------> the number

we know that

the expressions is equal to

\frac{1}{3} x=(x-12 )

therefore

<u>the answer part 2) is</u>

\frac{1}{3} x=(x-12 )

<u>Part 3)</u> "Ten increased by the quotient of a number and 2 is -15"

Let

x---------> the number

we know that

the expressions is equal to

10+ (\frac{x}{2} )= -15

therefore

<u>the answer Part 3) is</u>

10+ (\frac{x}{2} )= -15

<u>Part 4)</u> "One less than the product of a number and 3 is 5 more than the number itself"

Let

x---------> the number

we know that

the expressions is equal to

(3x)-1=5+x

therefore

<u>the answer Part 4) is</u>

(3x)-1=5+x

The perimeter of a rectangular parking lot is 296 m if the width of the parking lot is 65 m , what is its length
Sophie [7]

Answer:

166

Step-by-step explanation:

So the width is 65, so two sides are each 65m long. So multiply 65*2 which is 130. this means that the other two sides need to equal 130 when added, so divide 130/2 which is 65

What are the x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of
Mrrafil [7]

Answer:

\left ( \frac{3x_2+5x_1}{8},\frac{3y_2+5y_1}{8} \right )

Step-by-step explanation:

Given: P is Three-fifths the length of the line segment from K to J

To find: x- and y-coordinates of point P on the directed line segment from K to J

Solution:

Section formula:

Let point K and J be (x_1,y_1)\,,\,(x_2,y_2) such that the point p(x,y) divides KJ in ratio m:n

Then coordinates of point  P are given by \left ( \frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n} \right )

Take m:n=3:5

So,

coordinates of point P = \left ( \frac{3x_2+5x_1}{3+5},\frac{3y_2+5y_1}{3+5} \right )=\left ( \frac{3x_2+5x_1}{8},\frac{3y_2+5y_1}{8} \right )
