Answer: 50%

Step-by-step explanation:

imagine you had a pie and you cut it in half to discover their are two different flavors inside no more no less. by assuming theirs only two flavors how much would you say in percentage you would have...... it would be 50% because just like using quarters if you had 50 cents and 50 cents it would equal out to 100, in this case it would be percent you would say from the 2 groups that only 50 percent of the students would be likely to have that blood group

Match the equation with the step needed to solve it.

ziro4ka [17]

To solve this, you need to isolate/get the variable "m" by itself in the equation:

1. 2m - 1 = 3m Subtract 2m on both sides to get "m" on one side of the equation

2m - 2m - 1 = 3m - 2m

-1 = m

2. 2m = 1 + m Subtract m on both sides to get "m" on one side of the equation

2m - m = 1 + m - m

m = 1

3. m - 1 = 2 Add 1 on both sides to get "m" by itself

m - 1 + 1 = 2 + 1

m = 3

4. 2 + m = 3 Subtract 2 on both sides to get "m" by itself

m = 1

5. -2 + m = 1 Add 2 on both sides to get "m" by itself

m = 3

6. 3 = 1 + m Subtract 1 on both sides to get "m" by itself

2 = m

0 4

Step-by-step explanation:

This is a function table. For a linear function, find the average rate of change between the listed points called slope. Then use the slope to fill in other inputs and outputs for the function.

$m = \frac{y_2-y_1}{x_2-x_1}=\frac{4-0}{0-12} =\frac{4}{-12} =- \frac{1}{3}$

This means for every 3 units made in the input, the function moves down 1 output.

Kyle has 125 marbles. Fifty of these marbles are red and the reat are other colors. What is the ratio of the nunber of red marbl

Vedmedyk [2.9K]

Answer:

The required simplest form is: $\frac{2}{5}$

Step-by-step explanation:

We have been given Kyle has 125 marbles.

And 50 out of total 125 are red and rest of them are other colours

that means other colour marble are 125-50=75

we need to find ratio of the number of red marbles to the total of marbles

The rat io is: $\frac{50}{125}=\frac{2}{5}$

The required simplest form is: $\frac{2}{5}$
