Al and Erika went shopping for snacks. They bought bags of pretzels, p, and cans of almonds, a. Al bought 4 bags of pretzels and 2 cans of almonds for $19.30. Erika bought 5 bags of pretzels and 3 cans of almonds for $26.60. Their purchases can be modeled by the system of equations 4p+2a=19.30
5p+3a=26.60

Solve the system of equations for p and a. Show your work.

Explain what each numerical solution represents.

is means division by fractions

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
