Sagot :

1. 3x = 254 + 346
    3x = 600
   [tex] \frac{3x}{3}= \frac{600}{3} [/tex]
   x = 200

2. [tex] \frac{P100}{P12} = 8.33[/tex] final answer: 8 two-way fares.

3. 5 + [tex] \frac{n}{3} = \frac{n}{2} [/tex]
   5 + [tex]6( \frac{n}{3} ) = 6( \frac{n}{2} )\\5 + 2n = 3n\\5 = 3n - 2n\\5 = n[/tex]

4. [tex]V= s^{3} \\125 cm^3 = s^3\\ \sqrt[3]{125 cm^3} = s^3\\5 cm = s[/tex]
[tex]S.A=6s^2\\S.A = 6(5cm)^2\\S.A = 6(25cm^2)\\S.A = 150cm^2[/tex]

5. distance = 30 km            time = 40 mins. 
speed = [tex] \frac{d}{t} [/tex] 
[tex]speed= \frac{30km}{40mins.} = 0.75km/min[/tex]

6. [tex]5 \frac{625}{1000} = \frac{5625}{1000} = \frac{225}{40} [/tex]

7. 
Basic salary = P3500
Rate of Commission = 7% or 0.07
Sales =P 245 500
Salesman's earnings = x

P 245 500 (0.05) + P 4 500 = x
P 12 275 + P4 500 = x
P16 775 = x
