how to solve

-3(m-2)=-9

m= ?

Answers

Answer 1

9514 1404 393

Answer:

  m = 5

Step-by-step explanation:

Recognize that the number on the right has -3 as a factor. Divide both sides of the equation by -3.

  m -2 = 3

Add 2 to both sides of the equation:

  m = 5

_____

Additional comment

Perhaps the conventional approach is to eliminate parentheses, then solve the resulting 2-step linear equation.

  -3m +6 = -9

  -3m = -15 . . . . . . subtract 6 (step 1)

  m = 5 . . . . . . . . . divide by the coefficient of m (step 2)

highest common factor of 275 and 350?​

Answers

Answer:

25

Step-by-step explanation:

Factors of,

275 = 1, 5, 11, 25, 55, 275

350 = 1, 2, 5, 10, 7, 14, 25, 35, 50, 70, 175, 350

Highest common factor of 275 and 350 is 25.

The HCF of 275 and 350 is given by the equation A = 25

What is HCF and LCM?

The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF

Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers

Product of HCF x LCM = product of two numbers

Given data ,

Let the HCF of the two numbers be represented as A

Now , the equation will be

Let the first number be p = 275

The factors of 275 = 1 , 5 , 11 , 25 , 55 and 275

Let the second number be q = 350

The factors of 350 = 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175 and 350

So , the highest common factor of 275 and 350 is 25

Therefore , the value of A is 25

Hence , the HCF is 25

Answers

Answer:

Here the ratio of length of the shadow to the height of the object (in this case a yardstick) is 15:36. The ratio of shadow to the height of tree will also be the same. the shadow of tree is 25 feet long. So the height of tree will be (25*36)/15, that is 60 feet.

The sum of three consecutive odd integers is 2,193. What are the integers? (show your work)

Answers

Answer: x = 729

Step-by-step explanation:

729+731+733 = 2193

x+(x+2)+(x+4) = 2193

x + (x+2) + (x+ 4) = 2193
3x +6 = 2193
Subtract 6 on both sides of the equal sign.
3x =2187
Divide 3 on both sides of equal sign so that you isolate the variable
x= 729
729, 731, 733
To get the three numbers plug in x to each equation in the first line .
x =729 729+2 = 731 729+4 =733

Answers

Answer:

6 stops

Step-by-step explanation:

well if you stop every 2 1/4 miles for 13 1/2....13 1/2 divided by 2 1/4 is 6. So they'll stop 6 times.

The number of rest stops before finishing the trail is 5 rest stops.

Given,

You are hiking along a trail that is 13½ miles long.

you plan to rest every 2¼miles.

We need to find how many rest stops will you make.

How do distribute equally a given value?

We divide the given value by the total number of items we want to distribute.

Example:

= 7

We have,

Trail distance = 13 1/2 miles = 27/2 miles

Distance travelled before every each = 2 1/4 miles = 9/4 miles

The number of 4/9 miles in 27/2 miles.

= 27/2 / 9/4

= 27/2 x 4/9

= 27x4 / 2 x 9

= 3 x 2

= 6 times.

This means on the 6th time you have already finished the trail so,

You have rested 5 times before finishing the trail.

Thus the number of rest stops before finishing the trail is 5 rest stops.

Answer:

y = - x + 1

Step-by-step explanation:

y = mx + c ( m is the slope and c the y- intercept

y = 4 - x , that is y = - x + 4 ← in slope- intercept form

with slope m = - 1

The slope crosses the y- axis at (0, 1 ) ⇒ c = 1

Answers

Answer:

w = 21 feet

Step-by-step explanation:

The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet.

What is a rectangle?

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Let's say the length of a rectangle is L while the width is W.

According to the given, L = 3W - 5

The perimeter of the rectangle is given as 2( length + width)..

Perimeter = 2(L + W)

2(3W - 5 + W) = 158

4W - 5 = 79

W = 21 feet.

Hence "The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet".

D. y=-3x+1

E. 5x+10y=10

F. 6-2y=4x

Answers

Answer:

B and E

Step-by-step explanation:

The slope has to be 1/2 because the equation in the question is equal to 1/2 so only B and E are parallel

The equations of the line parallel to -3x-6y=30 are 4y=20-2x and 5x+10y=10. The correct options are B and E.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line is y = mx + c. Given that the equations are parallel to the line -3x-6y=30.

To check the line parallel to -3x-6y=30 find the slope of each line and if the slope is equal to the given equation of the line then both the lines will be parallel to each other.

The slope of the given equation of the line:-

-3x-6y=30

y = ( -1 / 2 )x + 5

Slope = -1 / 2

Check all the equations:-

A. 2x-y=15 or y = -2x + 15

B. 4y=20-2x or y = ( -1 / 2 )x + 5

E. 5x+10y=10 or y = ( -1 /  2)x + 1

Therefore, equations 4y=20-2x and 5x+10y=10 are parallel to the line -3x-6y=30.
