SIMPLE GEOMETRY QUESTION WORTH 13 POINTS!!! EASY EARNED POINTS!!! ANSWER ASAP!

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= -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

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:yes it is correct

Step-by-step explanation:

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.

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

Given that:

The expressions are [tex]3z−2, 2x^3+x-12, 9b, 9x-2[/tex].

Solution:

Monomial : It contains single terms.

Binomial : It contains two terms.

Trinomial :  It contains three terms.

Polynomial : It contains atleast one algebraic term.

Degree of polynomial : It is highest power of the variable.

[tex]3z-2[/tex] ,  here z is the variable. So, it is a polynomial with degree 1 and it is a binomial.

[tex]2x^3+x-12[/tex] ,  here x is the variable with highest power 3. So, it is a polynomial with degree 3 and it is a trinomial.

[tex]9b[/tex] ,  here b is a constant. So, it is not a polynomial and it is a monomial.

[tex]9x-2[/tex] ,   here x is the variable. So, it is a polynomial with degree 1 and it is a binomial.

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

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
