Answer:
36 people of them did not have a beach umbrella.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
Let x represents the number of people did not have a beach umbrella.
As per the statement:
Bella saw that 7 : 11 people brought an umbrella to the beach.
Out of 11 people, only 7 people brought an Umbrella to the beach.
Remaining people did not brought an Umbrella to the beach = 11 -7 = 4 people
It is also given that there were 99 people there.
then by definition of proportion:

By cross multiply we have;

Divide both sides by 11 we get;

Simplify:
x = 36 people.
Therefore, 36 people of them did not have a beach umbrella.
Answer: D
4x^4 + 3x^3 + 2x^2 - 11x -5
Step-by-step explanantion:
Flip and make the 4x-5 in the front and then multiply all terms by 4x and then all terms by -5 and then add both answers together.
If 3c+4d=2 then c=(2-4d)/3
And if you put that into the other equation

Then you multiply everything by 3, getting

And then

I dont have a calc with me right now but you just pot this into the calculator:

And when you get the number you insert it into the nest eqation to get c

So basically
Answer: the current value of the house is $343350
Step-by-step explanation:
The initial value of the house on the market was $315,000.
After several years the value increased by 9%. This means that the amount by which the value of the house increased over the years would be
9/100 × 315000 = 0.09 × 315000 = $28350
The current value of the house would be the sum of the previous value of the house and the increase in value. It becomes
315000 + 28350 = $343350
