I cannot understand this help me and I do not know what a scale factor is

Answers

Answer:

The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure. Example: Here, XYUV=123=4 . So, the scale factor is 4

Step-by-step explanation:

Answer:

the scale factor would be 4

Step-by-step explanation:

also  

A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. For example, doubling distances corresponds to a scale factor of two for distance, while cutting a cake in half results in pieces with a scale factor for volume of one half. The basic equation for it is image over preimage.

3 (m - 1) = 5m + 3 - 2m just solve it plz



dont answer if u dont know >:(

Answers

Answer:

No solution

Step-by-step explanation:

To solve the equation, we would have to find the value of m that would make the equality true.

3(m - 1) = 5m + 3 - 2m

Distribute the 3 on the left side.

3m - 3 = 5m + 3 - 2m

Combine like terms on right side.

3m - 3 = 3m + 3

Add 3 to both sides.

3m = 3m + 6

Subtract 3m from both sides.

0 = 6

Since 0 does not equal 6, there would be no solution to the equation, since no value of m would make 0 = 6 true.

Find a common multiple between 30 and 42 that is bigger than them.
(Note: I'm not finding the LCM I just need a multiple bigger than them)

Answers

Answer:

210

Step-by-step explanation:

GCF(30,42) = 6

LCM(30,42) = ( 30 × 42) / 6

LCM(30,42) = 1260 / 6

LCM(30,42) = 210

1260

1260 is a multiple of 30 and 42.
30(42)=1260,
multiplying both of these numbers means that the result will always be a common multiple.

8 - 1/3x=16
help meee

Answers

Answer:

- 24

Step-by-step explanation:

Step 1:

8 - 1/3x = 16      Equation

Step 2:

- 1/3x = 8     Subtract 8 on both sides

Step 3:

x = 8 ÷ - 1/3    Divide

Step 4:

x = 8 × - 3      Multiply

Answer:

x = - 24

Hope This Helps :)

The solution to the equation 8 - (1/3)x = 16 is x = -24.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Given equation 8 - (1/3)x = 16

1. Begin by isolating the term with the variable, (1/3)x,

by subtracting 8 from both sides of the equation:

8 - 8 - (1/3)x = 16 - 8

-(1/3)x = 8

2. Next, multiply both sides of the equation by -3 to eliminate the fraction:

-3 * (-(1/3)x) = -3 * 8

x = -24

Therefore, the solution is x = -24.

Answers

Answer:

x = 5

Step-by-step explanation:

- 4.95 -4.95

1.25x = 6.25

____ ____

1.25 1.25

x = 5

1.25x + 4.95 = 11.20
-4.95 = -4.95
1.25x = 6.25
1.25x/1.25 = 6.25/1.25
x = 5
