3a + 1 = -3.6(a - 1) \\\\3a + 1 = -3.6 a +3,6\ \  | \ add\ 3.6a\ to\ both\ sides  \\ \\ 3a + 3.6a+1 = 3,6\ \ |\ subtract\ 1\ to\ both\ sides \\\\6.6a=3.6-1 \\\\ 6.6a=2.6 \ \ | \ multiply\ both\ sides\ by\ 10  \\\\66a=26 \ \ | \ divide \ both \ sides\  by\ 66\\\\a=\frac{26}{66}\\\\a=\frac{13}{33}

The cattle train
speed - 36.5 km/h
time - x h

the passenger train
speed - 29.2 km/h
time - (2.4+x) h

The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.

36.5 \times x=29.2 \times (2.4+x) \\
36.5x=70.08+29.2x \\
36.5x-29.2x=70.08 \\
7.3x=70.08 \\
x=\frac{70.08}{7.3} \\
x=9.6 \\ \\ 2.4+x=2.4+9.6=12

The passenger train travelled for 12 hours before the cattle train caught up.

There are 16 girls in a school club the number of girls is four more than twice the number of boys find the number of boys
Nina [5.8K]

Answer:

Number of boys = 6

Step-by-step explanation:

It is given that:

Number of girls in school club = 16

Let,

b be the number of boys.

g be the number of girls.

g = 2b + 4

Putting g=16

16 = 2b + 4

16 - 4 = 2b

2b = 12

Dividing both sides by 2

\frac{2b}{2}=\frac{12}{2}\\b=6

Therefore,

Number of boys = 6
