Answer:

9

Step-by-step explanation:

Thirty divided by one hundred multiplied by thirty percent is equals to nine.

The value of 30% of 30 is 9

Given the expression

30% of 30

30% can also be written as 30/100 = 0.03

Substitute into the expression

30% of 30

= 0.3 * 30

= 9

Hence the value of 30% of 30 is 9

Answer:

x = (64 + 5) ÷ 3

Step-by-step explanation:

                                        3x - 5 = 64

Add 5 to both sides:            3x = 64 + 5 = 69

Divide both sides by 3:          x = 69 ÷ 3 = 23

So the answer is x = (64 + 5) ÷ 3

Note:  If we didn't add the parentheses then using the order of operation x = 64 + 5 ÷ 3 would be x = 64 + [tex]\frac{5}{3}[/tex] = 65 [tex]\frac{2}{3}[/tex]

Answer:

10 : 3

Step-by-step explanation:

Convert one of the measurements so that it is in the same form as the other.  (Easiest to convert m to cms so we are not working with decimals)

2.5 m = 2.5 x 100 = 250 cm (since there are 100 cm in a meter)

Therefore, as a ratio:

250 : 75

We can divide both by 5:

50 : 15

We can further divide by 5:

10 : 3

(no further simplifying)

So 2.5 m to 75cm as a ratio is 10 : 3

Multiply total serves by percentage:

The table helps the reader understand, ''the high number of refugees forced to relocate".

Given

The table shows Jewish emigration from Germany between 1933 and 1939.

The pressure placed on the Jewish people in Germany was the main factor that forced a high number of refugees to relocate.

The number of Jews in Germany in January 1933, was about 523,000. These Jews decided to leave the country after the Nazi takeover.

Emigration numbers were mostly 37,000 and they went to Belgium, Denmark, France, the Netherlands, and Switzerland, which always demonstrated an openness to receive the Jewish immigrants.

Hence, the table helps the reader understand, ''the high number of refugees forced to relocate".

Answer:

x = ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

3x² + 7 = 28 ( subtract 7 from both sides )

3x² = 21 ( divide both sides by 3 )

x² = 7 ( take square root of both sides )

x = ± [tex]\sqrt{7}[/tex]

that is x = - [tex]\sqrt{7}[/tex] , x = [tex]\sqrt{7}[/tex]

Answer:

A. +[tex]\sqrt{7}[/tex]

Step-by-step explanation:

3x^2+7=28
3([tex]+\sqrt{7} ^{2}[/tex] )+7=28

3(7)+7=28

Answer:

0.8

Step-by-step explanation:

To find a fraction as a decimal you divide the top by the bottom :

24÷30=0.8

The decimal of the fraction, 24 / 30 is 0.8.

Decimals are the numbers, which consist of two parts namely, a whole number part and a fractional part separated by a decimal point.

Therefore, let's convert the fraction 24 / 30 to a decimal number as follows:

Hence, let's divide both the numerator and denominator by 6

24 / 30 ÷ 6 / 6 = 4 / 5

Therefore,

4 / 5 = 0.8

Answer:

(-6,8)

Step-by-step explanation:

First, when we look at the graph, we need to look at where the two linear lines intersect. We find that they intersect at (-6,8). Now that we found the solution to the equation, that is the entitled answer.

First you need to find the discount amount. You do this by changing 15% into a decimal.

So,

15/100 = 0.15

Then we multiply,

0.15x12.33 = 1.8495 Or $1.85

Since there was a 15% discount, we have to subtract 12.33 by 1.85.

So,

12.33-1.85 = 10.48

If there is a 4.5% tax, we'll change 4.5% into a decimal.

So,

4.5/100 = 0.045

Then we multiply by the new amount,

0.045x10.48 = 0.4716

Now we have to add because it is a 4.5% tax.

So,

10.48+0.4716 = $10.95

Therefore, the new total cost was $10.95.

Answer:

-7/3

Step-by-step explanation:

2(6−4)=3(6+2)

2(6x-4)=3(6x+2)

Solve

1

Distribute

2(6−4)=3(6+2)

{\color{#c92786}{2(6x-4)}}=3(6x+2)

12−8=3(6+2)

{\color{#c92786}{12x-8}}=3(6x+2)

2

Distribute

12−8=3(6+2)

12x-8={\color{#c92786}{3(6x+2)}}

12−8=18+6

12x-8={\color{#c92786}{18x+6}}

3

Add

8

8

to both sides of the equation

12−8=18+6

12x-8=18x+6

12−8+8=18+6+8

12x-8+{\color{#c92786}{8}}=18x+6+{\color{#c92786}{8}}

Solution

=−7/3

Use distributive property and PEMDAS

2(6x-4)=3(6x+2)

12x-8=18x+6

now add like variables....

-12x on both sides..

6x-8=6

+8 on both

6x=14

divide 6 on both sides
