Answer:
9
Step-by-step explanation:
If S is between R and T, then RS+ST = RT
Given the following parameters
RS=2z+6,
ST=4z−3,
RT=5z+12
On substituting
2z+6+4z-3 = 5z+12
Collect like terms
2z+4z-5z = 12+3-6
6z-5z = 15-6
z = 9
Hence the value of z is 9
-2(x - 5) + 4(9 + x)
-2x + 10 + 36 + 4x
=2x + 46

Answer:
10m/s,15m/s,20m/s,5m/s
Step-by-step explanation:
Speed = distance / time
a) distance = 100m , time = 10s
Speed = distance / time
Speed = 100m/10s
Speed = 10m/s
b) distance = 300m , time = 20s
Speed = distance / time
Speed = 300m/20s
Speed = 15m/s
c) distance = 700m , time = 35s
Speed = distance / time
Speed = 700m/35s
Speed = 20m/s
d) distance = 1000m , time = 200s
Speed = distance / time
Speed = 1000m/200s
Speed = 5m/s
