Answer:

a=19

Step-by-step explanation:

First we have to distribute the parenthesis; multiply (a+5) by 1/3

8=1/3*a+1/3*5

Now we just solve the equation regularly

8=1/3a+5/3

8-5/3=1/3a

6 1/3=1/3a

a=19

Answer:

Step-by-step explanation:

8=1/3(a+5)

I do not know if you meant to put the (a=5) in the denominator or in the counter, so I'll try both.

if 8=1/3(a+5) and (a+5) is in the counter, this would get us;

8=(a+5)/3

<=> 8.3 = (a+5) = 24

<=> 24-5 = a = 19

is 8=1/3(a+5) and (a+5) is in the denominator, this would get us;

8=1/3(a+5)

<=> 3.8.(a+5) = 1 = 24(a+5) = 24a + (5.24)

<=> 1/24 = a+5

<=> 1/24 -5= a

mart [117]

Answer:

With the given margin of error its is possible that candidate A wins and candidate B loses, and it is also possible that candidate B wins and candidate A loses. Therefore, the poll cannot predict the winner and this is why race was too close to call a winner.

Step-by-step explanation:

A group conducted a poll of 2083 likely voters.

The results of poll indicate candidate A would receive 47% of the popular vote and and candidate B would receive 44% of the popular vote.

The margin of error was reported to be 3%

So we are given two proportions;

A = 47%

B = 44%

Margin of Error = 3%

The margin of error shows by how many percentage points the results can deviate from the real proportion.

Case I:

A = 47% + 3% = 50%

B = 44% - 3% = 41%

Candidate A wins

Case II:

A = 47% - 3% = 44%

B = 44% + 3% = 47%

Candidate B wins

As you can see, with the given margin of error its is possible that candidate A wins and candidate B loses, and it is also possible that candidate B wins and candidate A loses. Therefore, the poll cannot predict the winner and this is why race was too close to call a winner.

Help me this is hard

Following PEMDAS is crucial to solving these. Please Excuse My Dear Aunt Sally

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Multiplication/Division and Addition/Subtraction are interchangeable.

Now then, number 1 has the following:

$4-2*409-8*96$

There are no parenthesis or exponents, but there is multiplication, so we will start with multiplying. There are two multiplication expressions in the problem.

$-2 * 409 = -818$
