During a back-to-school shopping trip, a group of friends spent $245.86 on 14 shirts and pants. Each shirt cost $11.99. Each pair of pants cost $24.99. How many shirts and pairs of pants did the group buy? A. Write a system of equations to model the information in the problem.

B. Study the system. Explain, without solving, which method you think would be most efficient for solving the system: substitution, elimination, graphing, or making a table. C. Explain why the other methods would be less efficient.

C. How could you simplify the numbers used in this system to simplify the system? Does this new system change your answers to part (b)? Explain

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

a
