It saves us writing parentheses.
After two hours of driving she noticed that she covered 80 km and calculated that, if she continued driving at the same speed, she would end solging been 15 minutes late.
The stop was planned.
So the equation is:
The above statement is true for all values of x and therefore all real numbers are solutions to the given equation. Rewrite the equation in slope intercept form y = mx + b and identify the value of m the slope. More Intermediate and College Algebra Questions and Problems with.– Bruce, Anaheim, CA

We will start off this chapter with a fairly short section with some basic terminology that we use on a fairly regular basis in solving equations and inequalities. First, a solution to an equation or inequality is any number that, when plugged into the equation/inequality, will satisfy the equation/inequality. So, just what do we mean.– Sandra, Lexington, KY

How long is her book? Problem 4 A farming field can be ploughed by 6 algebga in 4 days. When 6 tractors work together, each of them ploughs hectares a day. If two of the tractors sklutions moved to another field, then the remaining 4 tractors could plough the same field in dolving days.
How many hectares a day would one tractor plough then? Hence, each of the four tractors would plough hectares a day. Problem 5 A student chose a number, multiplied it by 2, then subtracted from the result and got What was the number he chose? Problem 6 I chose a number and divide it by 5. Then I subtracted from the result and got 6. What was the problem solving in algebra with solutions I chose?
