Answer:
x=-
Step-by-step explanation:
subtract -3(2x-1)+8=15
-8 -8
_____________
-3(2x-1)=7
divide
then simplify
2x-1=
add both sides
2x-1+1=+1
simplify again
2x-1+1=+1=2x=
divide by 2
2x=
-2 -2
_________
2x÷2=1
x=-
Answer:
93+30=123 so e equals 123
Step-by-step explanation:
To check, do 123-30=93
A=4×-3 I think this is the equation
You must mean the depth of the submarine.
to make sum = zero the depth of the sub must be -1600 ft..
The distance travelled by an object is 50 m.
<h3>What is Distance?</h3>
The distance between two points is the length of the path connecting them.
Here, given equation of distance
S = 1/2 (u + v)t
Where s is the distance traveled by an object (in meters)
initial velocity u (in m/s)
final velocity v (in m/s).
t in seconds.
Now, given values are;
u = 8 m/s ; v = 12 m/s ; t = 5 sec.
S = 1/2 (8 + 12)5
S = 1/2 (20)5
S = 100/2
S = 50 m.
Thus, the distance travelled by an object is 50 m.
