What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given radical expression can be simplified as shown below,

5√20 - 3√45

Write the under root values in the factored form,

= 5√(4×5) - 3√(9×5)

Simply the function that can be simplified,

= 5(√4 × √5) - 3(√9 × √5)

= 5(2√5) - 3(3√5)

= 10√5 - 9√5

Take √5 as the common term from the two of the given terms,

= (10 - 9) √5

= 1 √5

= √5

Hence, the value of the expression when simplified is equal to √5.

An angle measures 40 more than the measure of its supplementary angle. What is the measure of each angle

Answers

Sum of two angles that are supplementary = 180°

Let the first angle be x .

Then the other angle = x + 40

Measure of each angle =

[tex]x + x + 40 = 180[/tex]

[tex]2x + 40 = 180[/tex]

[tex]2x = 180 - 40[/tex]

[tex]2x = 140°[/tex]

[tex]x = \frac{140}{2} [/tex]

[tex]x = 70°[/tex]

Which means :-

The first angle:-

[tex]= x = 70°[/tex]

The second angle :-

[tex]x + 40[/tex]

[tex]70 + 40[/tex]

[tex] = 110°[/tex]

Therefore , the two supplementary angles are 70° and 110° .

x < -8, third from top option in the picture.

Step-by-step explanation:

5(2x - 4) < -100

10x - 20 < -100

10x < -80

x < -8

Answer:

3rd option from the top (open circle arrow going left)

Step-by-step explanation:

5(2x-4) is less than - 100

5 times 2x is 10x and 5 times - 4 is - 20 so,

10x - 20 is less than - 100

now do inverse operations to isolate x, add 20

- 20 plus 20 is 0 and -100 plus 20 is - 80

10x is less than -80

divide both sides by 10 and you get,

x is less than - 8

Answers

Answer:

x= 17

HJ= 27

JK= 153

HK= 180

Step-by-step explanation:

If HJ=x+10

JK=9x

KH=14x−58

a) Draw a sketch of the segments described above

Find attached to this answer the diagram of the sketch of the segments described above

b) Write an equation using the segment addition postulate that will help you solve the problem

HJ + JK = KH

x + 10 + 9x = 14x - 58

c) combine like terms ( x terms on one side of the equal sign and numbers in the other side of the equal sign) x + 10 x + 10 + 9x = 14x - 58

10 + 58 = 14x - x -9x

68 = 14x - 10x

68 = 4x

x = 68/4

x  = 17

d)

x= 17

HJ= x + 10

= 17 + 10

= 27

JK= 9x

= 9 × 17

= 153

HK=14x −58

HK = 14 × 17 - 58

= 238 - 58

Given the above equation, what is the value of
10-[(a -3) - 7]?

Answers

Answer:

10

Step-by-step explanation:

a=3+7

a=10

10-[(10-3)-7]=

=10-[7-7]=

=10-0=

=10

The solution of expression 10 - [(a - 3) - 7] would be 10.

Given that,

The equation is,

-7 + a = 3

Now, we can simplify the equation as,

- 7 + a = 3

a - 7 = 3

Subtract 3 on both sides,

a - 3 - 7 = 0

(a - 3) - 7 = 0  .. (i)

Here, the equation to simplify is,

10 - [(a - 3) - 7]

Substitute the value from equation (i),

10 - 0

= 10

Therefore, the solution of expression is 10.

A shop sells bagels for $5 per dozen. You can use the table to answer
the questions. Explain your reasoning. (Show all your work)

1. At this rate, how much would 6 bagels cost?

2. How many bagels can you buy for $50?

Answers

Answer with step-by-step explanation:

Lets says the number of bagels is B and the price in dollars is D.

Equation: D × 12/5 = B

1. 6 is half of a dozen, which means the price would be half of 5, 2.5

2. $50 is 10× the amount of $5, so the amount of bagels would be 10 × 12, which is 120 bagels.

Hope this helped! (brainliest please)

A Dozen mathematically means 12.

It is important to note that:

$5 = 12 bagels

1) 12 bagels = $5

          6 bagels = ?

Cross Multiply

6 bagels  x $5 / 12

= $7.50

Therefore, 6 bagels would cost $7.50

2) $5 = 12 bagels

         $50 = ?

Cross multiply

$50 x 12 bagels / $5

= 120 bagels

Therfore, you can buy 120 bagels for $50
