I'm here buddy,
so, let's take the value of the two bags with equal weight as x.
= x + x + (x + 
) = 
= 3x + =
= 3x = -
( let's take the LCM of 4 and 5 = 20
= 3x = 
- 
= 3x = 
= x = ÷ 
= × 
= 
So, the weight of the equal bags are and the weight of the third bag ( heavy one ) is + = + = 
1st bag = kg
2nd bag = kg
3rd bag = kg
Hope it helps...
Answer:
90 stamps
Step-by-step explanation:
We can solve this by writing an equation.
(38+26)+26
64+26
90
Therefore, they have 90 stamps altogether.
Answer:
5x-18=4x+7 ( vertical opposite angle)
5x-4x=7+18
x=25
5π/12 = (5 · 180°) : 12 = 75°
cos 75° = cos ( 45° + 30° )= cos 45° cos 30° - sin 45° sin 30° =
=√2/2 * √3/2 - √2/2 * 1/2 =
=(2.4495 - 1.4142): 4 = 0.258825
