Answer:

x= -3

Step-by-step explanation:

Distribute 4(2-4x) which leaves you with 8-16x-3x=65

combine the like terms which leaves you with 8-19x=65

subtract 8 from both sides 8-19x-8=65-8 which leaves you with -19x=57

lastly divide -19 from both sides which leaves you with x= -3

Answer:

six thousand

Step-by-step explanation

it lies in place of thousand and value is 6

6* 1000=6000

The place value is thousand.

Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000. It is important that children understand that whilst a digit can be the same, its value depends on where it is in the number.

given number:

6,029

So, place values are as follows:

9- ones

2- tens

0- hundred

6 - thousand

Hence, the place of 6 is thousand

Step-by-step explanation: count 8, 17 times and that is how you get your answer

The length of the rectangle is 17 cm if the area of a rectangle is 136 square centimeters.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is given that:

The area of a rectangle is 136 square centimeters.

A  = 136 square cm

w = 8 cm

A = lw

136 = 8l

l = 17 cm

Thus, the length of the rectangle is 17 cm.

Answer:

1.33333333333

Step-by-step explanation:

|9x - 9| = 36

To solve for the first solution, simply disregard the absolute value signs.

9x - 9 = 36

Add 9 to both sides

9x = 45

Divide both sides by 9

x = 5

To find the second solution, disregard the absolute value signs and change 36 to -36

9x - 9 = -36

Add 9 to both sides

9x = -27

Divide both sides by 9

x = -3

Now, we need to find the sum of these two solutions.

5 + (-3) = 5 - 3 = 2

The measure of DE = 90 degrees because its corresponding central angle = 90 degrees.

Answer:

x = 29.8

Step-by-step explanation:

x represents the unknown number

20.7 + x = 50.5

x + 20.7 - 20.7 = 50.5 - 20.7

x = 50.5 - 20.7

x = 29.8

Answer:

x = 19

Step-by-step explanation:

Since C is between B and D , then

BC + CD = BD , substitute values

8x + 13 + 12x - 73 = 320 , that is

20x - 60 = 320 ( add 60 to both sides )

20x = 380 ( divide both sides by 20 )

x = 19

Answer:

550 $45 tickets, so $24750 worth of $45 tickets

Step-by-step explanation:

If $45 tickets=x, $65=y, and $95=z, then the question is saying x=y+z. And if x+y+z=1,100, then x=1100/2, so 550 $45 tickets. 550*45 is $24750

Step-by-step explanation:

Answer:yes it is correct

Step-by-step explanation:

Answer:

never true

Step-by-step explanation:

6(x + 1) = 2(5 + 3x)

distribute

6x + 6 = 10 + 6x

combine like terms by subtracting 6x and 6 from both sides

0 = 4

that is not a true statement, so this equation is never true

x + 84 = 4x

These are equal because they're vertical angles. Now, let's subtract x from both sides.

84 = 3x

Divide both sides by 3

28 = x

x + 84 = 28 + 84 = 112 degrees

Answer:

y = 1/7

Step-by-step explanation:

The value of x is 25 then y is 7.

In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.

Given:

y ∝ 1 √ x

and, y= 5 when x= 49

So, the relation will be

y ∝ 1/√x  

y = k/√x

So, 5 =  k/√49

5 = k /7

k = 35

Now, k = y/ √x

35 = y √25

35 = 5y

y = 7

Hence, when x is 25 then y is 7.
