When put in matrix form, the coefficients of
... 3x -2y = 7
... x + 4y = 2
look like
![\left[\begin{array}{cc}3&-2\\1&4\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D3%26-2%5C%5C1%264%5Cend%7Barray%7D%5Cright%5D%20%20)
The determinant is 3×4 - 1×(-2) = 14.

Tbe question doesn't state the number of days he walked to school out of 20 school days in the
Month of February.
Answer:
Kindly check explanation
Step-by-step explanation:
To. Obtain the fractional representayion for the number of days he walked to school ;
Let the number of days he walked to school = 10 (this is an hypothesized value)
Number of school days in February = 20
Fraction = 10 /20 = 0.5
The percentage of times walked to school : multiply the fraction obtained above by 100%
0.5 * 100% = 50%
Just put the desired value and proceed uSing the steps described above.
The reciprocal is 17/2 cause all you do is just flip the fraction
The length of the air conditioner is 24 feet.
Volume = 3600 feet ³
Width = 15 feet
Height = 10 feet
Length = Unknown
Therefore, the value of the length will be calculated thus:
Volume = Length × Width × Height
3600 = Length × 15 × 10
Length = 3600 / (15 × 10)
Length = 3600 / 150
Length = 24
The length is 24 feet
