8 h 30 min =7h 100 m 7h 100min-4h 55 min=3h 45 min
Unless you have a value for 'h', the answer will just be an expression: 10 + 7h
In the expression 7h + 3, the coefficient is 7, which is the numerical factor of the variable h. The constant is 3, which is a term without a variable attached to it. Coefficients and constants are essential components in algebraic expressions and equations, helping determine the value of the expression based on the variables involved.

(7h + 35) / (-7) = (7h)/(-7) + (35)/(-7) = (-h) + (-5) = - (h + 5)
8 h 30 min =7h 100 m 7h 100min-4h 55 min=3h 45 min
4h + 7h - 16 = 6 Combine like terms: 11h - 16 = 6 Add 16 to both sides: 11h = 22 Divide both sides by 11: h = 2
Unless you have a value for 'h', the answer will just be an expression: 10 + 7h
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.
It is: 11h
In the expression 7h + 3, the coefficient is 7, which is the numerical factor of the variable h. The constant is 3, which is a term without a variable attached to it.

The shades of graphite pencil from lightest to darkest are typically categorized as 9H (lightest), 8H, 7H, 6H, 5H, 4H, 3H, 2H, H, F, HB, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, 9B (darkest). The 'H' pencils are harder and lighter, while the 'B' pencils are softer and darker.
The order of hardness goes:9H 8H 7H 6H 5H 4H 3H 2H H F HB B 2B 3B 4B 5B 6B 7B 8B 9B hard medium soft
According to wikipedia hydrogen has three naturally occuring isotopes, 1H, 2H and 3H. 4H through 7H have been created in the laboratory but they are very short-lived.

H stands for hardness and B stands for blackness this is how a pencil scale goes: 9H 8H 7H 6H 5H 4H 3H 2H 1H H HB B 1B 2B 3B 4B 5B 6B 7B 8B 9B9H is very fine hard and light but 9B is thick black and very soft (more like charcoal)
