Answer:
a = 3
Step-by-step explanation:
When you add the given value for a with 7, the resulting answer must be less than 11.
In this case, if: a = 3
Plug in 3 for a in the equation:
7 + a < 11
7 + 3 < 11
10 < 11 (True).
A) a = 3 is your answer.

Answer:
Step-by-step explanation:
this is confusing b/c they are asking about two trains traveling at differnt speeds, but.. if you put the speeds together and make one train... imaginary.. ofc... traveling at the speed of both trains combined... when will it be 50 miles from the station?
maybe you can solve that? I'll solve it below.. but.. if you can.. try it now, on your own
below is my answer... don't look until you have solved yours :P
80+70= 150kph
when will this have traveled 50Km?
you may be able to see that it will take 1/3 of an hour to travel 50 km
so 60 minutes times 1/3 = 20 minutes :)
Answer:
d=20/3 or 6.6 repeating
Step-by-step explanation:
Let's solve your equation step-by-step.

Start by getting the term with the exponent on one side
take the log of both sides
There is a log rule that says we can bring down the exponent
Solve for x
5x=6.64
answer: x=1.33
First you can change 3 to 10/10 so that they can have the same denominator. Now, since you do that the number is now 2.
Now, do 10/10-1/10=9/10.
After do 2-4=-2.
So, your final answer is -2 9/10.
