Ответ:
Part A) see the explanation
Part B) see the explanation
Step-by-step explanation:
we have
Part A) Write an equivalent equation by multiplying the equation by 3.
Does the equation have the same solution set?
Multiply by 3 both sides
Remember that
The Multiplication Property of Equality states that if you multiply both sides of an equation by the same number, the sides remain equal
therefore
The equivalent equation have the same solution set by multiplication property of equality
Part B) Write an equivalent equation by dividing the equation by 2. Does
the equation have the same solution set?
Divide by 2 both sides
Remember that
The Division Property of Equality states that if you divide both sides of an equation by the same number, the sides remain equal
therefore
The equivalent equation have the same solution set by division property of equality

Number of Small Cones Sold=22
Number of Large Cones Sold=34
Step-by-step explanation:
Suppose,
Number of Small Cones Sold: s
Number of Large Cones Sold: l
For the condition that, larges cones sold were 12 more than small ones, equation would be
and for the total revenue condition of $163
By solving equation (i) and (ii) simultaneously, we get
s=22
and
l=34
Hence, small cones sold would be 22 and large cones sold would be 34.
