Ken wants to buy some coffee mugs, m , that cost $5 each and some ground coffee, C, that costs $8 a pound. He has $25.
ValentinkaMS [17]

The inequality representation of the scenario is :

  • 5m + 8c ≤ 25
  • m = 1 and c = 1

  • Number of mugs = m
  • Cost per mug = $5
  • Number of ground coffee = c
  • Cost per ground coffee = $8
  • Total amount to spend = $25

  • (Number of mug × cost per mug) + (Number of ground coffee × cost of ground coffee) ≤total amount to spend

  • Representing as an inequality : 5m + 8c ≤ 25

Combination of m and c that makes the inequality true :

  • Using trial by error :
  • m = 1 and c = 1
  • 5(1) + 8(1) ≤ 25 ; 13 ≤ 25

Hence, m = 1 and c =1 are valid values for the expression.

valentina_108 [34]

The answer is the option A, which is: A. Equilateral triangles.

The explanation for this answer is shown below:

By definition, a tetrahedron is a solid in three dimensions that has: six sides, four vertices and four triangular faces. These faces are equilateral triangles, which means that all the sides are equal and all the interior angles measure 60 degrees.

The tetrahedron is also called "triangular pyramid".
