It would be 4 and 6 i solved it
Let x be the price of Tanya's item. Tanya spent 5x, because she bought 5 of them.
The cost of Tony's item is x-1.75, because the price is 1.75 less than Tanya's. He spent 6(x-1.75), because he bought 6 of them.
They spent the same amount of money, so we have
So, Tanya's item costs 10.5, and Tony's item costs 8.75.
In fact, we have
<u>Answer:
</u>
Billy Bob’s farm is 80 m north of his house. The farms pond is 120 m west of the house. So the distance between the pond and the farm is 144.42 m.
<u>
Solution:
</u>
From question, given that billy bob’s farm is 80 m north of his house and pond is 120 m west of the house.
The given can be represented using the diagram given below:
where,
“a” indicates the distance between the house and the pond
“b” indicates the distance between the house and the farm
“c” indicates the distance between the farm and the pond.
For a right angled triangle, by Pythagoras theorem,
= 20800
Taking square root on both sides, we get
= 144.22 m
Hence the distance between the pond and farm is 144.22 m
Solution
For this case we can do the following:
A) 15, 21
LCM= 105
15= 3*5
21 = 7*3
LCM= 3*5*7
b) 15,30
LCM= 30
15= 3*5
30 = 2*5
LCM= 2*3*5= 30
c) 24,72
LCM= 72
24= 2*3*4
72= 2* 2*2*3*3
LCM= 2*2*2*3*3
d) 16,42
LCM= 336
16= 2*2*4
42= 2*3*7
LCM= 2*2*3*7*4
e) 8,30
LCM=120
8= 2*4
30= 2*3*5
LCM= 2*3*4*5=120
f) 18,30
LCM=90
18= 2*3*3
90= 2*5*3*3
LCM= 2*5*3*3
g) 8,16,20
LCM= 80
8= 2*2*2
16= 2*2*2*2
20= 2*2*5
LCM= 2*2*2*2*5
