The problem is "h+35=15".Subtracy 35 from each side, so h=-20.
The algebraic expression for "3 more than a number" can be written as x + 3, where x represents the unknown number. In this expression, the variable x is being increased by 3. This expression can be simplified further if needed, but the basic form is x + 3.
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.
h=20t-5t2+1
(7h + 35) / (-7) = (7h)/(-7) + (35)/(-7) = (-h) + (-5) = - (h + 5)
