Answer:
   500
Step-by-step explanation:
The problem statement tells you ...
   300 = 0.60×voters
Dividing by the coefficient of the variable gives ...
   300/0.60 = voters = 500
500 students voted in the election.

Answer:
When one shape can become another using only Turns, Flips and/or Slides, then the two shapes are Congruent. Two shapes are Similar when we need to Resize for one shape to become another (we may also Turn, Flip and/or Slide). So, when one shape can become another using transformation, the two shapes might be Congruent or just Similar?

Step-by-step explanation:
let us give all the quantities in the problem variable names.
x= amount in utility stock  
y = amount in electronics stock  
c = amount in bond
“The total amount of $200,000 need not be fully invested at any one time.”
becomes
x + y + c ≤ 200, 000,
Also
“The amount invested in the stocks cannot be more than half the total amount invested”
a + b ≤1/2 (total amount invested),
=1/2(x + y + c).
(x+y-c)/2≤0
“The amount invested in the utility stock cannot exceed $40,000”
a ≤ 40, 000
“The amount invested in the bond must be at least $70,000”
  c ≥ 70, 000
Putting this all together, our linear optimization problem is:
Maximize z = 1.09x + 1.04y + 1.05c
subject to
x+ y+ c ≤ 200, 000
x/2 +y/2 -c/2 ≤ 0
               ≤ 40, 000,
               c ≥ 70, 000
a ≥ 0, b ≥ 0, c ≥ 0.
