Step-by-step explanation:
a)
a whole circle represents always 360 degrees.
we see the angle J is 72 degrees. the angle K is 90 degrees.
that leaves us for M and L together :
360 - 72 - 90 = 198 degrees.
we now know that twice as many people voted for L as for M. that means the angle L is twice as big as the angle M
on other words : L = 2M
and when we now say
198 = L + M
this means
198 = 2M + M = 3M
M = 66 degrees
and L is then 2M = 2×66 = 132 degrees
b)
again, the whole circle is 360 degrees.
J covers 72 of these 360 degrees.
that is 72/360 of all voting people.
72/360 = 1/5
the total of all voting people was 15840.
so, 1/5 of 15840 is
15840/5 = 3168
that means 3168 people voted for J.
The width would have to be 15 because the perimeter is 60 inches then you divide it by 4 and ill give you 15
The right answer is 2)
Recall that, in systems of linear equations, when the number of equations is the same as the number of variables there is likely to be a solution. This is not guaranteed, but for sure it is possible to find a solution.
So the case of Infinitely many solutions claims for the same lines. These systems are called consistent. Thus, if we isolate the variable 
of each equation we have:
As you can see these equations are the same, therefore they represent the same line as indicated in the Figure below.
Answer:
3 hours and 35 minutes
Step-by-step explanation:
4 to 7 is 3 hours and then add at the 35 minutes
