Six people are standing in line for concert tickets. Their average age is 27. The average age of the first four people in line i

scZoUnD [109]

Let the age of the 4th person be F
Sum of the 1st four in line: 4(23), or 92
Sum of 1st 3: 92 - F (excludes the 4th person's age)
Sum of the last 3 in line: 3(34), or 102
Sum of last 2: 102 - F (excludes the 4th person's age)
Sum of all 6: 6(27), or 162 (INCLUDES 4th person's age)
We now get: F + 92 - F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
F, or 4th person's age = -32/-1, or 32

X=y+1400 0.08x+0.05=840

mezya [45]

Answer:

x = 7000

y = 5600

(7000, 5600)

Step-by-step explanation:

To solve the system of equations means to find the point of intersection (graphically). You are finding what value of 'x' and what value of 'y' fits both equations.

x = y + 1400

0.08x + 0.05y = 840

We can solve using the method substitution, where you replace a variable in one equation with an equivalent expression.

Since "x" is y + 1400, we can replace "x" in the second equation.

0.08x + 0.05y = 840

0.08(y + 1400) + 0.05y = 840

Distribute over brackets by multiplying 0.08 with y, then 0.08 with 1400.

0.08y + 112 + 0.05y = 840 Collect like terms (with "y" variable)

112 + 0.13y = 840

Now isolate "y" in the simplified equation.

112 - 112 + 0.13y = 840 - 112 Subtract 112 from both sides

0.13y = 728

0.13y/0.13 = 728/0.13 Divide both sides by 0.13

y = 5600 Solved for y

We can substitute "y" with 5600 in any other equation that has "x".

x = y + 1400

x = 5600 + 1400 Add

x = 7000 Solved for x

You may express the answer as a coordinate, or an ordered pair (x, y).

The solution is (7000, 5600).

There are approximately 113 million TVs in the United States. Each uses, on average, 76 W of power and is turned on for 6.3 hour

ioda

Answer:

$76 W *\frac{1kW}{1000 W}= 0.076 kW$

$0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}$

$113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh$

And finally we can convert this into money like this:

$54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6$

So they spent every day approximately in total $ 4815291.6 dollars

Step-by-step explanation:

For this case we can convert the average power into Kw like this:

$76 W *\frac{1kW}{1000 W}= 0.076 kW$

Now on average we know that one person use on average this power over 6.3 hours per day so then we have the following consumption rate:

$0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}$

And now we know the total population so then the total consumption per day would be:

$113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh$

And finally we can convert this into money like this:

$54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6$

So they spent every day approximately in total $ 4815291.6 dollars
