Solving Exponential Equations (lacking a common base)<br> 4^x-5=8
avanturin [10]

Answer:

x= 6 1/2 or 6.5

Step-by-step explanation:

4^x-5 =8

2^2(x-5) =2^3

since the base is equal, the powers are equal

2(x-5) = 3

2x - 10 = 3

2x = 3 + 10

2x = 13

2x/2 = 13/2

x = 6 1/2 or 6.5

Two kilos of taronges and three kilos of mandarins cost 11.50 euros. Three kilos of taronges and two of mandarins cost 11 euros.
Illusion [34]

Answer:

Hence the pricing for each product will be taronges with 2 euros and mandarins with 2.5 euros.

Step-by-step explanation:

Given:

2 kg of taronges and 3 kg mandarins cost 11.5 euros

3kg taronges and 2 kg mandarins cost 11 euros

To Find:

Price for each product

Solution:

<em>Consider </em>

<em>Taronges =x euros</em>

<em>Mandarins=y euros</em>

So by given condition,

2x+3y=11.5  ....................equation(1)

and 3x+2y=11 ..............equation (2)

So , using substitution method,

3x=11-2y

x=11-2y/3 .......equation (3)

Using above value in equation(1) we get ,

2(11-2y)/3+3y=11.5

y=(11.5*3-22)/5)

y=2.5 euros

Using above value in equation(3)  we get ,

x=(11-2y)/3

x=(11-2*2.5)/3

x=(11-5)/3

x=2 euros
