Solve ax + bx = c for x
a,b,c represent nonzero constants

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

1) 3x - 2 ≥ 0 ⇒ 3x ≥ 2 ⇒ x ≥ 2/3

2) 3x - 2 < 0 ⇒ 3x < 2 ⇒ x < 2/3

Answer:

A negative number

Step-by-step explanation:

I know this is right. Negative numbers represent opposites. If positive represents a movement to the right, negative represents a movement to the left.In the context of negative numbers, a number that is greater than zero is referred to as positive. Thus every real number other than zero is either positive or negative, while zero itself is not considered to have a sign. Positive numbers are sometimes written with a plus sign in front, e.g. +3 denotes a positive three.

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:

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

Answer: False

Answer:

3/5

Step-by-step explanation:

3y = ax + 7

3(4) = a(3) + 7

12 = 3a + 7

5 = 3a

3/5 = a

Best of Luck!

x = 3

y = 4

3y = ax + 7

By putting the values of x and y, we get

3(4) = a(3) + 7

or, 12 = 3a + 7

or, 12 - 7 = 3a

or, 5/3 = a

a = 5/3

12 = 5/3(3) + 7

or, 12 = 12

LHS = RHS

Hence, Verified.

Step-by-step explanation:

a=4 so 3a becomes 3x4.

3x4=12

12+6c^2

C=2 so 6c^2 becomes (6x2)^2

6x2=12 and 12x12 because of the exponent.

12x12=144

12+144=156

Answer:

22

Step-by-step explanation:

Step 1:

- 12x + 18 - 10x - 5 = - 31

Step 2:

- 22x + 18 - 5 = -31

Step 3:

- 22x + 13 = - 31

Step 4:

- 22x = - 44

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:

b when b³ = 8

Step-by-step explanation:

Value of c when c² = 8 :-

[tex]c^2 = 8\\=> c = \sqrt{8} = 2\sqrt{2} = 2.828[/tex]

Value of d when d³ = 9 :-

[tex]d^3 = 9 \\=> d = \sqrt[3]{9} = 2.080[/tex]

Value of b when b³=8

[tex]b^3 = 8\\=> b = \sqrt[3]{8} = 2[/tex]

Value of a when a² = 9

[tex]a^2 = 9\\=> a = \sqrt{9} = 3[/tex]

Comparing all the values of a , b , c , & d ..... we find that value of b is the least

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]
