Since 42% of the voters voted and 12000 people voted, we can conclude that:
12,000=42% of the population.
I set this up like this:
12,000=0.42 x, substituting x for the total population.
Divide both sides by 0.42 to get x by itself.
x= 28571.43.
Your final answer is 28,572 people, because you can't have 0.43 of a person.
If there are parentheses you add the exponent on the outside to the exponents inside that belong to a variable.
For the three you would just cube it regularly, but for the x you would add the 3 to the 2 that is already on the x
Answer:
x = 7
Step-by-step explanation:

distribute

combine like terms


x = 7
I think it would be 40 but that’s not a option so maybe 45?
Answer:
Height of the building = 77 ft.
Step-by-step explanation:
Let the height of the building (AB) = h feet
It's given that height of a woman (ED) = 5 feet 3 inches
≈ 5 feet +
ft
≈ 5.25 ft
Length of the shadow (BC) of the building = 55 ft
Length of the shadow (DC) of the woman = 45 in ≈ 3.75 ft
Since, both the triangles ABC and EDC are similar, their corresponding sides will be proportional.
By the property of similar triangles,


h = 
h = 77 ft
Therefore, height of the building will be 77 ft.
