a plane has 32 seats in class A and 50 seats in class B whose sale represents a total of € 14,600. However, only 10 seats have b

slavikrds [6]

The two equations would be

32a+50b=14600
10a+40b=7000
To solve, we need to eliminate one variable.... let’s eliminate b

4(32a+50b=14600) —> 128a+200b=58400
-5(10a+40b=7000) —> -50a-200b=-35000
So when we add them together’ we get 78a = 23400
So solve that and a= 300, so class a tickets cost 300 euros each

Substitute a=300 into first equation in the system of equations at the beginning and 32(300)+50b=14600 —> 9600+50b=14600 —> 50b = 5000 or b= 100, so the cost for class b tickets is 100 euros each

Consider the equation 7*e^0.1t=47 solve the equation for t. epress the solution as a logarithm in base-e

alekssr [168]

An equation is formed of two equal expressions. The equation 7*e^0.1t=47 can be expressed as t=[ln (47/7)]/0.1.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation 7*e^0.1t=47 in terms of logarithm in terms of base-e can be solved as,

$7e^{0.1t}=47\\\\e^{0.1t}=\dfrac{47}{7}\\\\0.1 t = {\rm ln}(\dfrac{47}{7})\\\\t = \dfrac{ {\rm ln}(\frac{47}{7})}{0.1}$

Hence, the equation 7*e^0.1t=47 can be expressed as t=[ln (47/7)]/0.1.

PLS ESTIMATE/ 67% of 8.7

Studentka2010 [4]

67 percent of 8.7

$\frac{67}{100} \times \frac{x}{8.7}$
$100x = 67 \times 8.7$

$100x = 582.9$

Divide by 100 on both sides to isolate the x

$x = 5.829$
Round up (to the nearest tenth place and whole number)

$x = 6$
$x = 5.8$
