3/5 of a number is 162. Work out the number. How do I do this AQA question?

Answer:

Step-by-step explanation:

5x-4+7x-8=180

12x-12=180

12x=192

x = 16

5(16)-4= 80-4= 76 degrees

7(16)-8= 112-8= 104 degrees

9y  +  5 = 104

9y = 99

y = 11

9(11) + 5 = 99 + 5 = 104

Answer:

[tex]=-3tv^2[/tex]

Step-by-step explanation:

So we have the expression:

[tex]\sqrt[3]{3t^4v^2}\sqrt[3]{-9t^{-1}v^4}[/tex]

To simplify, combine the two radicals. Since they have the same index, we can combine them. Thus:

[tex]=\sqrt[3]{(3t^4v^2)(-9t^{-1}v^4)}[/tex]

Combine like terms:

[tex]=\sqrt[3]{(3\cdot -9)(t^4\cdot t^{-1})(v^2\cdot v^4)}[/tex]

Multiply. When multiplying the exponents, simply add the exponents:

[tex]=\sqrt[3]{-27t^3v^6}[/tex]

Now, simplify. Note that -27 can be written as (-3)^3. t^3 can be written as (t)^3 and v^6 can be written as (v^2)^3. Thus:

[tex]=\sqrt[3]{(-3)^3(t)^3(z^2)^3}[/tex]

Combine them all under one exponent:

[tex]=\sqrt[3]{(-3tv^2)^3}[/tex]

Cancel out the cube root:

[tex]=-3tv^2[/tex]

And this is the simplest it can get.

And we are done :)

Edit: Typo

Answer:

-3v²t

Step-by-step explanation:

[tex]\sqrt[3]{3t^4v^2}  \sqrt[3]{-9t^-1v^4}[/tex]

= [tex]\sqrt[3]{3t} \sqrt[3]{v^2t} \sqrt[3]{-9v^4t^-1}[/tex]

= [tex]\sqrt[3]{3t} (-\sqrt[3]{9v^4/t)} \sqrt[3]{v^2t}[/tex]

= - [tex]\sqrt[3]{3t}  \sqrt[3]{v^2 9v^4/t}t[/tex]

= - [tex]\sqrt[3]{3}  \sqrt[3]{9t}  \sqrt[3]{v^6}[/tex]

= - [tex]\sqrt[3]{3*9}v^2t[/tex]

= - [tex]\sqrt[3]{27} v^2t[/tex]

= -3v²t

Answer:

- 1  3/4

Step-by-step explanation:

3/4 + -2 1/2

Get a common denominator of 4

3/4 - 2 1/2 *2/2

3/4 - 2 2/4

Rewriting

Subtracting since the signs are different and take the signs of the larger

2 2/4 - 3/4

Borrow from the 2

1  + 4/4 + 2/4  - 3/4

1 6/4 -3/4

1  3/4

The sign of the larger was negative  ( 2 1/2)

- 1  3/4

Answer:

Step-by-step explanation:

Interquartile R range of an ungrouped data is expressed as R = Q3-Q1 where;

Q3 is the third quartile

Q1 is the first quartile

Given the Car Dealership Number of Cars Sold GMC as 84 Chevrolet 81 Nissan 92 Toyota 92 Ford 95 Honda 94 Hyundai 80 Acura 72

First let us arrange them in ascending order;

72, 80, 81, 84, 92, 92, 94, 95

Q3 = 3(n+1)/4 th observation where n is the total number of cars

Q3 = 3(8+1)/4 = 27/4

Q3 = 6.75th observation

Q3 = 6th obsrvation - 0.75(7th observation - 6th observation)

Q3 = 92-0.75(94-92)

Q3 = 92-0.75(2)

Q3 = 90.5

The 6.75th observation of the data is 90.5

Q1 = (n+1)/4 th observation where n is the total number of cars

Q1 = (8+1)/4 = 9/4

Q1 = 2.25th observation

Q1 = 2nd observation - 0.25(3rd observation - 2nd observation)

Q1 = 80-0.25(81-80)

Q1 = 80-0.25(1)

Q1 = 79.75

Interquartile range = Q3 - Q1

Interquartile range = 90.5 - 79.75

Interquartile range = 10.75

Answer:

Value of m = r / [p + z]  

Step-by-step explanation:

Given:

Equation:

mp + mz = r

Find:

Value of m

Computation:

⇒ mp + mz = r

⇒ m [p + z] = r

⇒ m = r / [p + z]

Value of m = r / [p + z]

Answer:

part 1: the french distinguish friends by using un ami for boys. they use une ami for girls, and des amis for friends. they distinguish best friends by saying un meilleur ami for boys, une meillure amie for girls, and des meilleures amies (or des meilleurs amis depending on the gender) for best friends.

Answer:

3.25 pounds

Step-by-step explanation:

x + 4 (1/2) + 3 (1/2) = 11

x + 4.25 + 3.5 = 11

x + 7.75 = 11

x = 11 - 7.75

x = 3.25 pounds

Answer: B: 241.93*

Step-by-step explanation:

4•12=48

129.95•48= 6237.60

6237.60 - 5995.67 = 241.93

Answer:

5 x + 2

Step-by-step explanation:

Answer:

y = (-1/5)x + 2

Step-by-step explanation:

A line perpendicular to y = 5x + 2 would have a flipped opposite slope. Note the slope in the slope-intercept form:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

Flip the slope:

y = 5x + 2

y = (-1/5)x + 2

y = (-1/5)x + 2 is your answer.

Answer:

-1/18

Step-by-step explanation:

2/3n = -12

2 = -12 × 3n

2/-12 = 3n

-1/6 = 3n

or,

-1/6×3 = n

-1/18 = n

CHECK:

2/3n = -12

2/3(-1/18) = -12

2/(-1/6) = -12

2×6/-1 = -12

-12 = -12

n = -18 will make the equation true.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

Given the equation,

2/3n = -12

Multiply both sides by 3/2

(2/3) × (3/2)n = -12(3/2)

n = -6 × 3

n = -18

Hence "n = -18 will make the equation true".

Answer:

x  = 3√3 - 3

x  = -3√3 - 3

Step-by-step explanation:

(3+x)² + 9 = 36

(x + 3)² + 9 - 9 = 36 - 9

(x + 3)² = 27

x + 3 = 3√3

x + 3 = -3√3

therefore,

x  = 3√3 - 3

x  = -3√3 - 3

Step-by-step explanation:

Length of an arc formula:

[tex]\displaystyle \frac{\theta }{360} \cdot \pi d[/tex]

The angle formed at the centre is 150 degrees.

The diameter of the circle is 34 centimeters.

[tex]\Longrightarrow \displaystyle \frac{150}{360} \cdot \pi (34)[/tex]

[tex]\Longrightarrow \displaystyle \frac{85}{6} \pi[/tex]

Step-by-step explanation:

Use FOIL method

[tex](\sqrt{2} -1)(2-\sqrt{2})= \sqrt{2}*2 -\sqrt{2}*\sqrt{2} -1*2-1*(-\sqrt{2})\\\\\\=2\sqrt{2} - 2 -2 +\sqrt{2}[/tex]

Answer: 11

Step-by-step explanation:

Given: Mr. Doss pulled out 16 negative counters and 27 positive counters.

In integers we use negative sign "-" to represent the negative quantities.

So, we can represent 16 negative counters as -16.

Now, combined value of the counters = (-16) + 27

= 27-16

= 11

Hence, the combined value of the counters is 11.

Answer:

[tex]m_1.m_2 = -1[/tex]

Step-by-step explanation:

Given

2 lines of same slope

A different perpendicular line

Required

Determine the relationship between the lines

We have that, line 1 and line 2 have the same slope;

Represent their slope with m₁

For the third line

Represent the slope with m₂

in coordinate geometry, the relationship between perpendicular line is

[tex]m_1.m_2 = -1[/tex]

Hence, the required relationship is [tex]m_1.m_2 = -1[/tex]

Step-by-step explanation:

when there is a expression in parentheses, change the sign of each term in the expression

-2x + 3 - 5 + 6x

collect the like terms

-2x + 6x = 4x

3 - 5= -2

now put them together and you get
