The total surface area consists of the base area and the surface area (the area of all lateral faces). The base is a hexagon with side a=3 cm.
sq. cm.
Each lateral face is an isosceles triangle with height h=12 cm and base a=3 cm. The area of one such lateral triangle is
sq. cm.
Then the total surface area is:
sq. cm.
Answer: 119.7 sq. cm.
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.
Equation: number of bracelets bought × cost of each bracelet = total cost
Number of bracelets bought: 7
Total Cost: 49
Using this information, we can fill in the equation and solve for x.
7x = 49
To isolate x, divide both sides by 7.
x = 7
Since x equals 7, we now know that each bracelet cost $7.
-3x=2x+19
-19 -19
-3x-19=2x
+3x +3x
-19=5x
/5 /5
x=19/5
