Answer:

Step-by-step explanation:

21 = 3*7

65 = 5*13

CGF: to find the greatest common factor, multiply those factors both numbers have in common

GCF :1 since there are no factors in common

Answer: 1 ✔

Step-by-step explanation:

The factors of 21 are: 1, 3, 7, 21

The factors of 65 are: 1, 5, 13, 65

Then the greatest common factor is 1.

They both contain a one in their factors so the GCF for both is 1.

$3 \frac{4}{7}m =8 \frac{1}{3} \\ \\\frac{25}{7}m=\frac{25}{3} \\ \\ m= \frac{25}{3}: \frac{25}{7}= \frac{25}{3}* \frac{7}{25}= \frac{7}{3}=2 \frac{1}{3}$

What is the location of the point (5, 0) translates 4 units to the down and reflected across the y-axis?

CaHeK987 [17]

STEP-BY-STEP EXPLANATION:

Given information

The given ordered point = (5, 0)

Step 1: We need to translate the point 4 units down

To translate down means we will be subtracting a value from the y--axis

Hence, we have

$\begin{gathered} (x,\text{ y) }\rightarrow\text{ (x, y-b)} \\ \text{where b = 4} \\ (5,\text{ 0) }\rightarrow\text{ (5, 0 - 4)} \\ (5,\text{ 0) }\rightarrow\text{ (5, -4)} \end{gathered}$

When translated 4 units down, we got (5, -4)

Step 2: Reflect over the y-axis

The general rule for reflecting over the y-axis is (-x, y)

This means the value of x will be negated and the value of y will remain the same

$\begin{gathered} \text{Over the y-ax}is \\ (x,\text{ y) }\rightarrow\text{ (-x, y)} \\ (5,\text{ -4) }\rightarrow\text{ (-5, -4)} \end{gathered}$

Step 3: the graph the point

Pani-rosa [81]

Answer:

Step-by-step explanation:

this is a set problem (mathematical set)

30 students played soccer

9 students played cricket and soccer

x students played neither cricket nor soccer

3x students played cricket only.

we can see that in the first set 21 appears and in the middle of the set 9 because it says 30 students played soccer adding x and 3x we have the following formula

30 + x + 3x = 50 where x is equal to 5 then ask us Determine the number of students who played cricket. then the value would be 3x + 9 = (3x5) + 9 = 24
