Step-by-step explanation:

3\cdot \:4+\left(-9\right)-x=10

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

3\cdot \:4-9-x=10

\mathrm{Multiply\:the\:numbers:}\:3\cdot \:4=12

12-9-x=10

\mathrm{Subtract\:the\:numbers:}\:12-9=3

-x+3=10

\mathrm{Subtract\:}3\mathrm{\:from\:both\:sides}

-x+3-3=10-3

Simplify

-x=7

\mathrm{Divide\:both\:sides\:by\:}-1

\frac{-x}{-1}=\frac{7}{-1}

Simplify

x=-7

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
