Answer:

Step-by-step explanation:

Answer:

Teo= 9

Richard= 24

Step-by-step explanation:

x= Richard

y= Teo

33-15= 18

18÷2= 9

15+9=24

Teo is 6 years old and Richard is 27 years old.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Let x be Teo's age, then Richard's age is 15 years older than twice Teo's age, or 15 + 2x. The combined age of Richard and Teo is 33, so we can write an equation:

x + (15 + 2x) = 33

Simplifying and solving for x, we get:

3x + 15 = 33

3x = 18

x = 6

So Teo is 6 years old and Richard is 15 + 2(6) = 15 + 12 = 27 years old.

sorry its kinna hard to explain

Answer:

9x^2 - 10x -4

Step-by-step explanation:

It is set up like this

     9x^2 - 8x

-              (x-2)2

First solve (x-2)2

the answer is (2x-4)

so now you can do this instead

    9x^2 - 8x

-              2x - 4

----------------------------------

9x^2 - 10x +4

9x^2 minus zero is 9x^2

-8x-2x is -10x

0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive

A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus

like this

    9x^2 - 8x

+              -2x + 4

----------------------------------

9x^2 - 10x +4

Answer:

6 1/4

Step-by-step explanation:

Given

Total number of wheel chance = 25

Each play = 1 quarter

1 play = 1/4

To calculate the amount Maya has to spend to get her winning number, we will say;

25 plays = x

Divide both expressions

1/25 = 1/4÷x

1/25 = 1/4x

Cross multiply

4x = 25

x = 25/4

x = 6 1/4

This mean that Maya will have to spend 6 1/4 before she gets her winning number

Answer:

[tex]\sqrt{10}[/tex]

Step-by-step explanation:

This is a 45-45-90 triangle whose leg to hypotenuse ratio is 1 / [tex]\sqrt{2}[/tex]

so I set up a proportion of 1 / [tex]\sqrt{2}[/tex] = x / 2 [tex]\sqrt{5}[/tex]

cross-multiply to get [tex]\sqrt{2}[/tex]x = 2[tex]\sqrt{5}[/tex]

x = 2[tex]\sqrt{5}[/tex] / [tex]\sqrt{2}[/tex] and multiply numerator and denominator by [tex]\sqrt{2}[/tex], this is called rationalizing the denominator

lets do

[tex]\\ \sf\longmapsto \sqrt{2}x=2\sqrt{5}[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{2\sqrt{5}}{\sqrt{2}}[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{2}\sqrt{5}[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{2(5)}[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{10}[/tex]

Answer:

One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons. One method of finding the answer in the fraction form of 3/8 is to multiply the fraction 1/2 by 3/4 : )

Step-by-step explanation:

One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.

Here, we have,

given that,

what is half of 3/4 teaspoon

One method of finding the answer in the fraction form of 3/8 is

to multiply the fraction 1/2 by 3/4 ,

or, we can divide 3/4 by 2

i.e. 1/2 × 3/4

as, half = 1/2

so, we get,

=> 3/ 2×4

=> 3/8

=>0.375

Hence, One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.

Answer:

2.4%

Step-by-step explanation:

The value of R is, 2.4%

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

Given that;

Louis invested £2950 in a savings account for 5 years.

He was paid 1.9% per annum compound interest for each of the first 4 years.

And, He was then paid R% interest for the fifth year.

Louis had £3257 in his savings account at the end of the 5 years.

Here, We know that;

⇒ Compound interest formula = Capital × (1 + r%) ⁿ

Where, n is time in years.

So, We can formulate;

⇒ £2950 × (1 + 0.019)⁴

⇒ £3180.67

And, For calculate R;

⇒ £3180.67 × (1 + R%)⁵ = £3257

⇒ R = 2.4%
