Q1:
1 tripod and 10 bipods/7 tripods and 1 bipod.
3+3+3+2+3+2+3+2+2=23
4 bipods
5tripods
4 bipods =8 legs
5 tripods=15 legs
15+8=23
Or
3 tripods= 9 legs
7 bipods= 14 legs
9+14=23
7 Bipods = 14 legs
3 Tribods = 9
4 Bipods = 8 legs
5 Tripod = 15 legs
Great responses so far Class 3!
If you haven’t had a go yet, why not give it a try?! ?
There are 8 tripods
1 bipods
7×3=21
1×2=2
21+2=23
So we have 7 tripods and 1 bipod
1×3=3
10×2=20
20+3=23
So we have 10 bipods an 1 tripod
Hi everyone
The answer is 4 tripods and 5 bipods to make 23 you can also make 23 using 7 bipods and 3 tripods.??????????☺️??????????
I found two solutions and there are only 2 solutions because to get an odd number in total, you need an odd number of Tripods greater than 2.
4 Bipods and 5 Tripods
7 Bipods and 3 Tripods
I worked it out by doing
3+2=5
23÷5=4.3
3×5=15
2×4=8
15+8=23
Answer: 5 tripods 4 bipods
or you can work it out like this
I used 3 because the tripod have 3 legs
3×3=9
23-9=14
14÷2=7 bipods
9+14=23
Answer: 3 tripods and 7 bipods
there are 4 tripods =12
there are 3 bipods=6
10 Bipods + 1 Tripod = 23 legs
7 Tripods + 1 Bipod = 23 legs
There are 3 tripods and 7 bipods
7 tripods
3 legs x 7 tripods=21
We added one bipod to get 23 legs
2 legs x 10 bipeds=20
We added one tripod to get 23 legs
1 tripod =3 legs
1 bipod=2 legs
Altogether 23
1. T.- 3×3=9
B.- 2×7=14
9+14=23
2. B.- 2×4=8
T.- 3×5=15
8+15=23
There are two possibilities:
1) 3 Tripods and 7 Bipods
3×3=9 legs
7×2=14 legs
9+14=23 legs
2) 5 Tripods and 4 Bipods
5×3=15 legs
4×2=8 legs
15+8=23 legs
Well done Class 3 for posting all of your answers today. If you haven’t answered yet, there’s still some time! I will reveal the answers in tomorrow’s Maths challenge post.
1 tripod has 3 legs
1 bipod has 2 legs
?
5 tripods x 3 legs= 15 legs
4 bipods x 2 legs = 8 legs
15+ 8 = 23 legs
?
3 tripods x 3 legs= 9 legs
7 bipods x 2 legs = 14 legs
14 + 9= 23 legs
Answer 1. 3 tripods 7 bipods.
Answer 2. 4 bipods 5 tripods.
1. 7 Tripods&1Bipod
2. 5Tripods&4Bipods
