Answer:
the greatest common factor of 36 and 84 is 12
1. 3x-10=x+70
+10 -x
2x=80
x=40
2. x+27+2x-39=180
3x-12=180
+12
3x = 180
x = 64
3. 2x ÷ 80=5x+44
- 2x -44
36= 3x
12=x
We can solve this problem using the Triangle Inequality property. The Triangle Inequality property states that the sum of two sides of a triangle will always be greater than the third. That being said, the only answer that works is the last one, which has the answer of 9 cm, 15 cm, and 22 cm.
Answer:
So new price of per liter petrol is 96 p
Step-by-step explanation:
Given:
Price of Petrol = 80p
Increase in price = 20%
To find :
Cost per liter = ?
Solution:
As it is given that old price of petrol is 80p
Increase in price = 20 % of Old Price
New Price = Old price + Increase in price
Now first we will find increase in price
Increase in price = 20 % of 80
It could be written as
=
=
Increase in price = 16 p
New price = old price + original price
= 80 p + 16 p
= 96 p
So new price of per liter petrol is 96 p
