Answer:
A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane. ... The lines intersect at infinitely many points.

To find the median, add up the frequency column to find how many trains there were in total. There were 44 trains in total in this grouped frequency table, so work out 44 + 1 2 = 45 2 = 22.5. The median is therefore between the 22nd and 23rd values.

D
Step-by-step explanation:
Not difficult just review the logarithmic functions.
Good luck my friend.
4x+3=3(x+3)
4x+3=3x+9
4x-3x=9-3
x=6
So The Father is 24 and the Son is 6
1 quart is approximately 9.464 x 10⁻⁴ cubic meter, so the amount of oil that was spilled is about
0.50 qt = (0.50 qt) * (0.0009464 m³/qt) = 4.732 x 10⁻⁴ m³
The pool has a cross sectional area of (25.0 m) * (30.0 m) = 750 m² = 7.5 x 10² m².
Assuming the oil spreads completely across the surface of the pool, you can get its thickness by dividing the volume of oil by this cross sectional area.
(4.732 x 10⁻⁴ m³) / (7.5 x 10² m²) = 4.732/7.5 x 10⁻⁶ m ≈ 6.309 x 10⁻⁷ m
1 m is exactly 100 cm, so multiply this result by 100 = 10² to get a thickness of
6.309 x 10⁻⁷ m = (6.309 x 10⁻⁷ m) * (10² cm/m) = 6.309 x 10⁻⁵ cm
or 0.00006309 cm.
