The least common multiple would give you the answer you are looking for.
Multiples of
6: 6, 12, 18, 24, 30, .....
9: 9, 18, 27, 36, .....
He will have a lesson on the same day in 18 days.
Starting on Tuesday we need to go 18 days. 14 days would be another Tuesday, Wednesday = 15, Thursday = 16, Friday = 17, Saturday = 18

Question
What is the GCF for 12 and 9? WILL GIVE BRAINLIEST FOR MOST DETAILED ANSWER!
Solution 1
12: 1,2,3,4,6,12

9: 1,3,9

That sounds about right to me. in order to find the Greatest Common Factor (GCF) look for the common factors that it has (:
Solution 2
First, write down all the factors for 9 and 12:
9) 1, 3, 9
12) 1, 2, 3, 4, 6, 12

The greatest number that both lists share is 3, so 3 is your GCF.
Question
Solution 1
4.5w = 5.1w - 30

4.5w - 5.1w = -30

-0.6w =-30

Divide both sides by -0.6

-0.6w/-0.6 = -30/-0.6

w = 50

Solution 2
4.5w = 5.1w - 30

4.5w - 5.1w = -30

-0.6w =-30

Divide both sides by -0.6

-0.6w/-0.6 = -30/-0.6

w = 50

I hope this helps.

Question
How can you use geometry figures to solve real world problems?
Solution 1
Archetecture and basic building

Solution 2
Architecture- based on mathematics and physics- more precise geometry. Figures were used long long ago, even before Christ. One of the biggest inventions, and the most contributing, and world known best inventions was a circle. That was the first step for machines. Geometry figures and angles are not just used in buildings, but in art- like sculptures (for example, before Christ in the Ancient Greece).

Solution 1
When finding the answer find the Greastest comman factor of the 3 toys which is 15. Then, divide each toy by the GCF. Therefore the answer is dolls= 3 shelves footballs = 7 shelves and small cars = 5 shelves.
