There is not enough information to complete the equation.

Answer:

a) Quantos estudam Inglês ou Espanhol?

477

b) Quantos fazem espanhol?

210

c) Quantos não estudam nenhuma dessas línguas?

193

Step-by-step explanation:

a) Quantos estudam Inglês ou Espanhol?

Inglês ou Espanhol = Quantidade de alunos que cursam inglês + Quantidade de alunos que cursam espanhol - Quantidade de alunos que cursam inglês e espanhol

= 352 + 210 - 85

= 477

b) Quantos fazem espanhol?

Isso é dado na pergunta como alunos que só aprendem espanhol = Somos informados de que o número de alunos que estudam apenas espanhol = 125

Número de alunos que cursam espanhol = Número de alunos que cursam apenas espanhol + Número de alunos que cursam espanhol e inglês

Número de alunos que fazem espanhol = 125 + 85

= 210 alunos

c) Quantos não estudam nenhuma dessas línguas?

Número total de alunos - (número de alunos que não cursam nenhum dos idiomas) = ​​Número de alunos que cursam inglês + Número de alunos que cursam espanhol - Número de alunos que cursam os dois

= 670 - (número de alunos que não estudam nenhum dos idiomas) = ​​352 + 210 - 85

= 670 - (número de alunos que não estudam nenhum dos idiomas) = ​​477

Número de alunos que não cursam nenhum dos idiomas = 670 - 477

= 193 alunos

Answer:

x = [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Given

- 3 - 39x = 11x - 23 ( subtract 11x from both sides )

- 3 - 50x = - 23 ( add 3 to both sides )

- 50x = - 20 ( divide both sides by - 50 )

x = [tex]\frac{-20}{-50}[/tex] = [tex]\frac{2}{5}[/tex]

Answer:

q-0

p-3

Step-by-step explanation:

there are two ways to solve elimination or substitution method I'll use the latter

so take the second equation and find an expression equal to p

p-2q=3

p=2q+3

substitute the above expression in the first equation

(2q+3)1+2q=3

open brackets

2q+3+2q=3

collect like terms

4q+3=3

solve

4q=0

q=0

substitute q in any equation you want I'll choose the second

p-(2×0)=3

p-0=3

p=3

Answer:

p = 3 ; q = 0

Step-by-step explanation:

In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that

[tex]p + 2q=3[/tex] & also [tex]p -2q=3[/tex] . So, we can also equate them as :-

[tex]p + 2q = p-2q[/tex] (∵ Both the eqn. have 3 in their right hand side product )

Solving the eqn. gives,

[tex]=> 2q + 2q = p-p\\=> 4q=0\\=>q=0[/tex]

Putting the value of q in any one of the linear eqn gives ,

[tex]p+2q=3\\=> p+2(0)=3\\=>p+0=3\\=>p=3[/tex]

Answer:

$80.59

Step-by-step explanation:

You add the price of the raincoat and shoes to get 152.75, you then subtract the price of the 4 shirts you returned to get 76.75. The 5% tax for this is 3.84 so you add the two together and you get $80.59.

Answer:

False

Step-by-step explanation:

Each toss is an independent event, so the probability of three tosses of heads in a row is the product of the three probabilities..

Each probability of heads is

p(heads) = 1/2

p(heads, heads, heads) = p(heads) * p(heads) * p(heads) = 1/2 * 1/2 * 1/2 = 1/8

Your Answer is 7

Step-by-step explanation:

Very Simple!

x-6 = -3x + 22

Move the 6 over to the other side by adding 6 to both sides

x = -3x + 28

add 3x to both sides!

4x = 28

Divide by 4!

x = 28/4

x = 7!

Answer:

x=7

Step-by-step explanation

x-6 = -3x +22

Answer: [tex]\frac{8}{9}[/tex]

Step-by-step explanation:

When you multiply fractions, it is the same as adding or subtracting, but you don't have to worry about having a common denominator. All you have to do is multiply straight across and simplify.

[tex]\frac{4}{3}*\frac{2}{3} =\frac{8}{9}[/tex]

Now we know the answer is [tex]\frac{8}{9}[/tex].

Answer:

8/9

Step-by-step explanation:

The answer is 8/9 because:

1) Whenever we multiply fraction, we have to multiply the numerator and the denominator together: numerator x numerator/denominator x denominator

2) Therefore, 4 x 2/ 3 x 3 = 8/9

Step-by-step explanation:

Step 1:

Step 2:

- 22x + 18 - 5 = -31

Step 3:

Answer:

x = 22

Hope This Helps :)

Answer:

Your answer is x = 2

Step-by-step explanation: [tex]-12x + 18-10x-5 = -31[/tex]

subtract 18 - 5 = 13 and add -12x+(-10x)= -22x

[tex]-22x+13=-31[/tex] subtract 13 on both sides

[tex]-22x+13(-13)=-31(-13)[/tex]  cross out +13(-13) and -31-13= -44

[tex]-22x=-44[/tex] divide -22 on both sides

[tex]\frac{-22x}{-22} = \frac{-44}{-22}[/tex] cross -22x/-22 and divide -44 and -22= 2

Answer:

The total number of cups is 9 1/2 cups

Step-by-step explanation:

Here, we are interested in calculating the total cups of trail mix that Mr V can make.

From the question, we are told that he used 1/2 cups of peanuts, 2 1/4 cups of raisins and 2 times more sunflower seeds than raisins.

So basically, we need to find the number of cups of sunflower seeds used.

The information we have here is that he used 2 times more of raisins;

Thus, the number of cups of sunflower would be 2 * 2 1/4 = 2 * 9/4 = 9/2. But practically is 9/2 , two times more than 2 1/4? NO!

What we should do here is to add 9/2 to 2 1/4. In that case, the difference between the two will be 2 times the cups of raisins;

So 9/2 + 9/4 = (18 + 9)/4 = 27/4

So the total number of cups of trail mix that can be made will be;

1/2 + 27/4 + 9/4 = (2 + 27 + 9)/4 = 38/4 = 19/2 = 9 1/2 cups

Answer:

slope of line is 0.

Step-by-step explanation:

Slope of a line passing through (x1,y1) and (x2,y2) is given by

m = (y2-y1)/(x2-x1)

Given points are  (10,5) and (9,5)

thus

slope = (5-5)/(9-10) = 0/-1 = 0

Thus, slope of line is 0.

When slope of line is zero it means that the line the which passes through given point is parallel to x-axis.

The slope of the line that passes through the points (10,5) and (9,5) is 0.

Using slope formula,

m = y₂ - y₁ / x₂ - x₁

Therefore,

(10,5) (9,5)

m = 5 - 5 / 9 - 10

m = 0 / -1

m = 0

Therefore, the slope of the line that passes through the points (10,5) and (9,5) is 0.
