There are no solutions. You can do this by either the substitution or the subtraction method , but either way you get no solutions.
If you multiply 4 times both sides of equation 1 you get
4h + 4 c = 12
If you subtract the second equation from it, you get 0 =/ does not equal -2.

You can clearly see there will be no solutions . These two lines will not intersect.

A plane travels 360,000 meters in 900 seconds. What was its speed
Umnica [9.8K]
900 / 60 = 15
So, the plane traveled 360,000 meters in 15 minutes.
Generally, we do per hour. So, 15 mins * 4 = 60 mins or 1 hour. Because we multiplied the time by 4, we also need to multiply the distance by 4. 360,000 * 4 = 1440000 meters. The plane was traveling at 1440000 meters per hour.

However, it does not make sense to use meters for this long of a distance. I am going to convert it into miles (let me know if the question asks for a different unit of distance). 1 mile equals 1609.34 meters. Divide 1440000 by 1609.34 to get how many miles. 1440000 / 1609.34 = 894.7767408.

Therefore, the plane is going about 895 miles per hour--pretty fast!

"At ​$1.29 million​, they closed last month for...26 percent above what they paid in​ 2007." How much did they pay in​ 2007?
Morgarella [4.7K]

Answer:  Amount that they paid in 2007 is 1.01 millions.

Step-by-step explanation:

Since we have given that

Number of millions paid last month = $1.29 millions

According to question, it was 26% above what they paid in 2007.

Let the amount paid in 2007 be x

So, our equation becomes,

\frac{100+27}{100}\times x=1.29\\\\\frac{127}{100}\times x=1.29\\\\1.27\times x=1.29\\\\x=\frac{1.29}{1.27}\\\\x=1.01\ millions

Hence, Amount that they paid in 2007 is 1.01 millions.
