Answer:

3x = 2x + 3.

Step-by-step explanation:

In the question it has been given that three times a number is three more than twice the number.

Let the number is x.

Then by the given statement 3x = 2x + 3

So equation formed can be used to find the value of x

3x - 2x = 3

x = 3

Therefore, the number is 3 and equation to be solved for x is 3x = 2x + 3.

Let the value of the number be represented as x. 

Then, write out an equation; 

3x=2x+3 <--- Solve for x now 
3x-2x=3 
x=3 

Therefore the number is 3. 

Hope I helped :)

Name the place of the highlighted digit. then write the value of the digit 35.052
AysviL [449]

Solution:

Given: 35.052

The standard form is: 35.052

3 is in the tens place. 3 = 3 × 1

5 is in the tens place. 5 = 5 × 1

0 is in the tenths place. 0.0 = 0 × 1/10

5 is in the tenths place. 0.05 = 5 × 1/100

2 is in the tenths place. 0.002 = 2 × 1/1000

The circumference of a circular garden is approximately 24 feet. What is the approximate area inside the circular garden? What i
diamong [38]

Answer:

45.86 ft²

Step-by-step explanation:

Circumference of a circle = 2 * pi * r

Circumference = 24

24 = 2 * 3.14 * r

24 = 6.28r

r = 24 / 6.28

r = 3.8216 ft

Approximate area of garden :

Area of circle :

pi * r^2

Area = 3.14 * 3.8216^2

Area = 45.8585273984

Area = 45.86 ft²

A line has a slope of -4 and passes through the point (0,-6) how do you do this ?
Murrr4er [49]

Answer:

y = -4x-6

Step-by-step explanation:

point slope form

y-y1 = m(x-x1)

y--6 = -4 (x-0)

y+6 = -4(x)

solve for y

subtract 6 from each side

y = -4x-6

A line through the points $(2, -9)$ and $(j, 17)$ is parallel to the line $2x + 3y = 21$. What is the value of $j$?
lys-0071 [83]

Answer:

j=-37

Step-by-step explanation:

step 1

Find the slope of the given line

we have

2x+3y=21

Convert to slope intercept form

Isolate the variable y

subtract 2x both sides

3y=-2x+21

divide by 3 both sides

y=-\frac{2}{3}x+7

The slope is

m=-\frac{2}{3}

step 2

we have the points

(2,-9) and (j,17)

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute

m=\frac{17+9}{j-2}

m=\frac{26}{j-2}

Remember that

If two lines are parallel then their slope are equal

therefore

\frac{26}{j-2}=-\frac{2}{3}

26(3)=-2(j-2)\\78=-2j+4\\2j=4-78\\2j=-74\\j=-37
