the answer is 
subtract 6x on both sides → 
divide both sides by -2y →
<u>Answer:</u>
BC = 18 cm
<u>Step-by-step explanation:</u>
As we can see from the diagram:
AB + BC + CD = AD
⇒ 10 cm + BC + 11 cm = 39 cm
⇒ BC + 21 cm = 39 cm
⇒ BC = 39 cm - 21 cm
⇒ BC = 18 cm
Two sides are congruent to each other.
The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.
A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
A triangle with all sides of different lengths. All angles are different, too. So no sides are equal and no angles are equal.

Answer:
We need to sell the nuts at 35 dollars to make $20 profit
Step-by-step explanation:
Profit = Selling price - cost
We know we want a 20 dollar profit
The cost of the nuts is 15 dollar
Substitute this in
20 = Selling price -15
Add 15 to each side
20+15 = Selling price -15+15
35 = Selling price
We need to sell the nuts at 35 dollars to make $20 profit
We know that
<span>the Consumer Price Index
(CPI) is equals to
</span>CPI=100*[cost of the pizza today/cost of the pizza <span>in the base year]
[</span>cost of the pizza in the base year]=100*[cost of the pizza today/CPI]
cost of the pizza today=$12
<span>CPI=200
so
</span>[cost of the pizza in the base year]=100*[12/200]-----> $6
<span>
the answer is
</span>The cost of the pizza in the base year is $6<span>
</span>
