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:
<h3>A. </h3>- log
= log 3
- x³ log x = log 3
- 3x³ log x = 3 log 3
- x³ log x³ = log 3³
= 3³
- x³ = 3
- x =
- 4ˣ + 6ˣ = 9ˣ
- 2²ˣ + 2ˣ3ˣ = 3²ˣ
<u>Divide both sides by 2²ˣ</u>
- 1 + (3/2)ˣ = (3/2)²ˣ
<u>Substitute (3/2)ˣ = t</u>
- t² - t - 1 = 0
<u>Solve for t:</u>
- t = (1 ± √5)/2
<u>Positive root is considered as (3/2)ˣ can't be negative.</u>
- (3/2)ˣ = (1 + √5)/2
- x = log [(1 + √5)/2] / log (3/2)
- x = 1.18681439028
