Answer:

Step-by-step explanation:

The cost per sandwich when 3 are delivered is $20/3 or $6.67 each.

The cost per sandwich when 4 are delivered is $26/4 or $6.50 each.

The average cost per sandwich changes with the number delivered, so it is not proportional.  The cost decreases per sandwich as the volume of sandwiches increases.  One can't predict the cost of 6 delivered sandwiches based on the information provided.  If it were proportional, the cost could be calculated on the basis of the slope of the line.  If all sandwiches cost $6.50 each, regardless of the volume ordered, the slope of a line relating number ordered and total cost would have a constant slope of 6.50.  That isn't the case in this problem.  The slope keeps changing.

Complete the pairs of corresponding parts if △ABD ≅ △EFC.
vovangra [49]

Answer:

We conclude that:

∠A = ∠ FEC

Step-by-step explanation:

Given

△ABD ≅ △EFC

To determine:

∠A =

As

△ABD ≅ △EFC

So the triangles △ABD and △EFC are congruent to each other.

  • We know that congruent triangles have equal corresponding parts.

Please check the attached graph.

From the graph, it is clear that ∠A is correspondent to ∠E.

∠A = ∠E

From the attached figure, it is clear that:

∠F can also be denoted by ∠ FEC

as

∠A = ∠E

so

∠A = ∠ FEC

Therefore, we conclude that:

∠A = ∠ FEC

Mashcka [7]
Use substitution
x -4x - 7 = 2
-3x = 9, x = -3
Y = -4(-3) - 7
Y = 12 - 7, y = 5
Solution: x = -3, y = 5
