Answer:

x = 1

Step-by-step explanation:

f(x) = 3 or y = 3

Locate y = 3 on the y- axis , go horizontally across to meet the line at (1, 3 )

Then

When f(x) = 3 , x = 1

Answer:

Rational ...................

Step-by-step explanation:

A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number

Answer:

In one month he earn €2,100

He worked whole year

1 year = 12 months

So,

George earning is 12 months = 12 × Earning of one month

=> 2100 × 12

=> 25200

Step-by-step explanation:

7x - 5 = 8

7x = 8 + 5

7x = 13 (divide both sides by 7 to get x)

7x/7 = 13/7

x = 1.85714285714

Answer:

Oi, tudo bem?

A resposta seria: Desse grupo, 20 mulheres não seriam estrangeiras.

Step-by-step explanation:

Esse grupo é formado por 400 pessoas, ao qual:

Homens:

30% = 30/100 = 0,3

400 . 0,3 = 120

Mulheres (Estrangeiras):

65% = 65/100 = 0,65

400 . 0,65 = 260

Neste caso, temos duas formas de resolver: ou descobrir a porcentagem da quantidade de mulheres que não são estrangeiras (isto é, '100% - (35% + 60% = 5%'), depois fazer a mesma fórmula como acima, que seria:

5% = 5/100 = 0,05

400 . 0,05 =  20

Ou também, podemos somar a quantidade de pessoas que nós já sabemos (que seria: '120 + 260 = 380') e subtrair a quantidade total de pessoas com esse resultado, que é:

400 - 380 = 20

Espero ter ajudado, bons estudos amigo(a)! ;)

Using the information in the exercise to develop the system of equations and using the substitution method, the following answers are found:

The system of the linear equations is P = F + 0.50, 2D = 3F - 0.50, and 2P + F + 3D = 7.75, where P = The price of a box of popcorn, D = The price of a drink, and F = The price of a piece of fruit. By other hand, the price of each item is: Popcorn = $1.50, Drink = $1.25, and Fruit = $1.

Solution of the system of equations by the Substitution Method.

Taking into account the information given in the exercise, we can write the next equations:

Where:

Since all equations have the variable F, we are going to use it as a key variable to represent the other variables in terms of F.

In the first equation we should not do anything, since P is in terms of F, in the second case the variable D is also in terms of F, but we need to find the value of just D, by this:

We proceed to substitute the first and second equations in the third equation:

And we solve for the variable F:

Now, we can solve for the variable D with the second equation:

Finally, we can solve for the variable P with the first equation:

So, we have the price of each item:

Answer:

125

Step-by-step explanation:

If you mean a 20 inch cube box then the answer is 125. Since 4 inch cubes have dimensions 4x4x4 and 20 inch cubes have dimensions 20x20x20. Then we can find the answer by dividing 20x20x20 by 4x4x4 which is equal to 5x5x5 as 20/4 = 5. Therefore the answer is 5x5x5 which is 125.

Answer:

x=11

y=3

Step-by-step explanation:

(9x+25)=(13x-19)

9x+25 = 13x−19

9x+25-25 = 13x−19-25

9x=13x-44

9x-13x=13x-44-13x

-4x= -44

x=11

y= 180-(9x+25)

y= 180-(99+25)

y= 180-124 = 56

y= 56-5 = 51

y= 51/17

y= 3
