Answer:
2440.
Step-by-step explanation:
If earth is a certain amount greater than the radius you are trying to find you would take earths measurements and take away what was said to be greater than mercury. Then after you do all the math you come up with mercurys radius measurements.
The required matrix is:
![\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-25%2617%260%5C%5C8%26-1%263%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
We need to apply elementary row operation -2R₂+3R₁ tothe matrix:
![A=\left[\begin{array}{ccc}-3&5&2\\8&-1&3\\\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%265%262%5C%5C8%26-1%263%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiplying Row 2 with -2 and Row1 with 3 and adding,
-9 15 6
-16 2 -6
----------
-25 17 0
After applying this operation, Row 1 will be changed while Row 2 will remain same because we get -2R₂+3R₁ -> R₁
The required matrix is:

Answer:
8 games
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Total amount = $150
Spent on Parking = 1/5 or 20% = $150 × 20% = $30
Spent on admission = $37
Spent on food = 40% = $150 × 40% = $60
Spent on admission in waterpark = $10
Each game cost = $1.5
So, let number of games played be X, then
$30 + $37 + $60 + $10 + $1.5X = $150
$137 + $1.5X = $150
1.5X = $150 - $137
1.5X = $13
X = $13 ÷ 1.5 = 8.67 or 8 games
Hence, Henry can play 8 games.
