Answer:

3m=18+12

3m=30

divide both sides by 3

m=10

Answer:

m = 10

Step-by-step explanation:

3m - 12 =18

Add 12 to each side

3m - 12+12 =18+12

3m = 30

Divide by 3

3m/3 = 30/3

m = 10

Answer:

y=-2

Step-by-step explanation:

9(y−4)−7y=5(3y−2)

(9)(y)+(9)(−4)+−7y=(5)(3y)+(5)(−2)

9y+−36+−7y=15y+−10

(9y+−7y)+(−36)=15y−10

2y+−36=15y−10

2y−36=15y−10

Step 2:

2y−36−15y=15y−10−15y

−13y−36=−10

Step 3:

−13y−36+36=−10+36

−13y=26

y=-2

Answer:

y=-2

Step-by-step explanation:

Simplifying

9(y + -4) + -7y = 5(3y + -2)

Reorder the terms:

9(-4 + y) + -7y = 5(3y + -2)

(-4 * 9 + y * 9) + -7y = 5(3y + -2)

(-36 + 9y) + -7y = 5(3y + -2)

Combine like terms: 9y + -7y = 2y

-36 + 2y = 5(3y + -2)

Reorder the terms:

-36 + 2y = 5(-2 + 3y)

-36 + 2y = (-2 * 5 + 3y * 5)

-36 + 2y = (-10 + 15y)

Solving

-36 + 2y = -10 + 15y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-15y' to each side of the equation.

-36 + 2y + -15y = -10 + 15y + -15y

Combine like terms: 2y + -15y = -13y

-36 + -13y = -10 + 15y + -15y

Combine like terms: 15y + -15y = 0

-36 + -13y = -10 + 0

-36 + -13y = -10

Add '36' to each side of the equation.

-36 + 36 + -13y = -10 + 36

Combine like terms: -36 + 36 = 0

0 + -13y = -10 + 36

-13y = -10 + 36

Combine like terms: -10 + 36 = 26

-13y = 26

Divide each side by '-13'.

y = -2

Simplifying

y = -2

Step-by-step explanation: good luck on your algebra Nation test

The number 4.5x10⁻⁶ can be expressed in standard notation as decimal 0.0000045.

In scientific notation, numbers are expressed as a decimal number between 1 and 10 multiplied by a power of 10. In this case, 4.5 is the decimal number and 10⁻⁶ represents the power of 10.

To convert this to standard notation, we move the decimal point six places to the left to match the negative exponent of 10⁻⁶. This gives us:

0.0000045

In standard notation, this number is written as 0.0000045, where the zeros after the decimal point indicate the value of the number in the place of each digit. The last non-zero digit in this case is 5, which is in the sixth decimal place.

Answer:

7/8

Step-by-step explanation:

Given the length of the actual movie time and the length of the total movie time, the actual movie is 7/8 of the total movie time.

Given the data in the question;

Total time of the movie is 2 hours and 40 minutes = 160 minutes

Preview time is 20 minutes

Now time of the actual movie will be;

Total time of the movie - Preview time

2 hours and 40 minutes - 20 minutes

160 minutes - 20 minutes

Time of the actual movie is 140 minutes

Now we get the fraction

Time of the actual movie / Total time of the movie

= 140 minutes / 160 minutes

= 14/16

= 7/8

Therefore, given the length of the actual movie time and the length of the total movie time, the actual movie is 7/8 of the total movie time.

Answer:

Answer:

substitute value of x and y as 2 and 4

y=5x-6

4= 5*2-6

4=4 so yes

Step-by-step explanation:

The point (2, 4) lie on the line y = 5x-6

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

For example, 3x + 5 = 15.

Given that, we need to check whether the point 2,4 lie on the line y=5x-6 or not,

So, the verification of the same, we will simply put the value of x (2) in the equation and see whether we are getting 4 or not, if not then points do not lie on the line, if yes, the point lies on the line.

So, the equation is

y = 5x-6

Put x = 2,

y = 5(2) - 6

y = 10-6

y = 4

Since, we get the value of y = 4, therefore, the point lies on the line.

Hence, the point (2, 4) lie on the line y = 5x-6

Answer:

r = 7

Step-by-step explanation:

Step 1: Write out equation

4r + 7 = 35

Step 2: Subtract 7 on both sides

4r + 7 - 7 = 35 - 7

4r = 28

Step 3: Divide both sides by 4

4r/4 = 28/4

r = 7

Solve 4r+7=35

4r=35-7

4r=28

r=7
