Mrs fields sold pens at 55 cents each and markers at $2 each. she sold 40 pens and markers altogether and collected $59.70

a) if mrs fields sold x pens, express in terms of x for the number of markers that she has sold.

b) form an equation in x connecting the cost of pens and that of markers that were

c) solve the equation to find the number of markers

me !

What is the solution of the equation? 35√(x+2)3+3=27

Can random samples and proportional reasoning be used to determine precise information about a population? explain

How are the solutions for |x +4|< -2 and |x +4| < 2 different? a they are not different, because the inequality is an absolute valueb the first inequality has no solution because absolute value cannot be negativec for one the solution is benveen two numbers. for the other, the solution is outside of the twonumbersd. for one the solution is a range of positive numbers, for the other, the solution is a range of negativenumbers
