Answer:

4w+10=-w

w=-2

Step-by-step explanation:

First, write out the equation in the algebraic form to make it easier to solve. This equation written out is 4w+10=-w. Then, isolate the variable and solve. Do this by subtracting 4w from both sides. Then, divide both sides by -5.

Step-by-step explanation:

only the second one fulfills the rule that every value of x must have exactly 1 assigned result value (y).

the first option has two different result values (3 and 5) for x = 1.

the third has 2 different result values (3 and 4) for x = 2.

the fourth has 2 different result values (2 and 4) for x = 2, and also 2 different result values (0 and 2) for x = 0.

84²

it is like saying 84×84

so

84×84=7,056

so our answer is

= 7,056

Step-by-step explanation:

M = 4/9 + 11/72

M = (4 x 8) / (9 x 8) + 11/72

M = 32/72 + 11/72

M = 43/72

N = 8/15 - 1/3

N = 8/15 - (1 x 5) / (3 x 5)

N = 8/15 - 5/15

N = 3/15

N = (3 x 1) / (3 x 5)

N = 1/5

O = 8/7 + 9/35

O = (8 x 5) / (7 x 5) + 9/35

O = 40/35 + 9/35

O = 49/35

O = (7 x 7) / (7 x 5)

O = 7/5

P = 3 - 2/10

P = (3 x 10) / (1 x 10) - 2/10

P = 30/10 - 2/10

P = 28/10

P = (2 x 14) / (2 x 5)

P = 14/5

Q = 11/15 + 1/6

Q = (11 x 2) / (15 x 2) + (1  x 5) / (6 x 5)

Q = 22/30 + 5/30

Q = 27/30

Q = (3 x 9) / (3 x 10)

Q = 9/10

R = 3/4 - 7/10

R = (3 x 5) / (4 x 5) - (7 x 2) / (10 x 2)

R = 15/20 - 14/20

R = 1/20.

Can you pls give a bit more information.

Step-by-step explanation:

Answer:

Julio: 65 soles

Agosto: 85 soles

Step-by-step explanation:

julio: x

agosto: x + 20

x + x + 20 = 150

2x + 20 = 150

2x = 130 x = 65

julio: x = 65

agosto: x + 20 = 85

verificacion: 65 + 85 = 150

julio [65] = 20 menos que agosto [85]

Answer:

Julio: 65 soles

Agosto: 85 soles

The consumption in July was 65 soles and the consumption in August was 85 soles.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Let's call the amount of consumption in July "C1" and the amount of consumption in August "C2".

We know that:

C1 + C2 = 150 (the total consumption for both months)

C2 = C1 + 20 (August consumption was 20 soles more than July)

We can substitute the second equation into the first equation to get:

C1 + (C1 + 20) = 150

Simplifying this equation, we get:

2C1 + 20 = 150

Subtracting 20 from both sides, we get:

2C1 = 130

Dividing both sides by 2, we get:

C1 = 65

So the consumption in July was 65 soles.

Using the second equation, we can find the consumption in August:

C2 = C1 + 20 = 65 + 20 = 85

So the consumption in August was 85 soles.

We can check that these values are correct by verifying that they add up to the total consumption of 150 soles:

65 + 85 = 150

Therefore,

The consumption in July was 65 soles and the consumption in August was 85 soles.

The complete question:

Since the quarantine began, the consumption of electrical energy in my house has increased. It is because we are all at home without going out, using the computer, television and other devices at the same time. The last receipt came to us in July and August, since we could not go out to pay for the quarantine, but the receipt was lost. I can only remember that the total amount was 150 soles and that in July consumption was 20 soles less than in August. How much was our consumption in July and August? Check your answer.

Answer:

Option B: (x= -8, y=10, z=-6)

Step-by-step explanation:

2x + 4y + 3z = 6 ... eq.(1)

5x + 8y + 6z = 4 ... eq.(2)

4x + 5y + 2z = 6 ... eq.(3)

From eq.(1),

2x= 6 - 4y - 3z

x= (6-4y-3z)/2 ... eq.(4)

Putting x as (6-4y-3z)/2 in both eq.(2) and eq.(3)

In eq.(2),

5[(6-4y-3z)/2] +8y +6z =4

Multiplying through by 2

5(6-4y-3z) + 16y + 12z = 8

30-20y-15z+16y+12z = 8

22= 4y + 3z ... eq(5)

In eq.(3),

4[(6-4y-3z)/2] +5y +2z = 6

2(6-4y-3z) +5y + 2z =6

12-8y-6z + 5y +2z = 6

6= 3y + 4z ... eq.(6)

Multiplying eq.(5) and eq.(6) by 3 & 4 respectively

66=12y + 9z ... eq(8)

24=12y + 16z ... eq(9)

Subtracting eq(8) from eq(9)

42= -7z

z= -42/7

z = -6

Putting z as -6 in eq.(5)

22= 4y + 3(-6)

22= 4y -18

4y = 40

y = 40/4

y = 10

Putting y as 10 and z as -6 in eq(4)

x = [6 - 4(10) - 3(-6)]/2

x = (6 - 40 - 18)/2

x = -16/2

x = -8

x= -8, y= 10 , z= -6

Step-by-step explanation:

Answer:

is this even a real question?

Step-by-step explanation:

Answer:

B. 30

Step-by-step explanation:

2m^2 + 12

m = 3

2(3)^2 + 12

3 squared is 9

2(9) + 12

2 times 9 is 18

18 + 12 = 30

2m^2 + 12 = 30

So we subtitute 3 to any "m" in your problem so,

2m^2+12

2(3)^2+12

2(9)+12

18+12

30

So,  B is the correct answer!
