Answer:
15 days
Step-by-step explanation:
3x5=15 days
The GCF stands for greatest common factor. To represent a sum by its GCF we need to use the distributive property and we need to first find the GCF of the numbers. Let's break each number by its factors:

We now multiply the numbers that appear on both.

We now apply the distributive property:
Answer: 9 × 6 = 54
Step-by-step explanation:
In the Product Game, we need to multiply the both number of factor markers.
Chris and Katie were playing The Product Game. Their factor markers were on 9 and 2.
Number = 9 × 2 = 18
Chris decided to move the marker from 2 to 6.
Now, one maker is on 9 and other is on 6. So,
Number = 9 × (2 + 4)
Number = 9 × 6 = 54
Therefore, 9 × 6 = 54 is a numerical expression to represent his move.
Answer:
The given system of equations has solutions below:
1) The solution is (2,3)
2) The solution is (
)
3) The solution is infinitely many solutions
4) No solution
Step-by-step explanation:
Given system of equation are


To solve equation by using elimination method
Multiply eqn (2) into 2

Now subtracting (1) and (3)


_________________
7x=14
x=

Substitute x=2 in equation (1)
-2+2y=4
2y=4+2

y=3
Therefore the solution is (2,3)
2) Given equation is

4y-4=x
Rewritting as below

To solve equation by using elimination method
multiply (2) into 2

Adding (1) and (3)
-2x+y=3
2x-8y=-8
________
-7y=-5

substitute
in (1)




Therefore the solution is (
)
3) Given equation is 

equation (1) can be written as
2(3x+y)=10

3x+y=5
Therefore equations (1) and (2) are same therefore it has infinitely many solutions
4) Given equation is 

multiply equation (1) into 2

To solve equation by using elimination method
subtracting (2) and (3)
-2x-4y=28
-2x-4y=12
_______

therefore it has no solution
