Answer:

The expression 9n + 1 represents the perimeter

sum of the sides of the triangle, equal to the perimeter:    

                                                                          x +  3n+2 + 2n-1 = 9n + 1

                                                                                    x +  5n + 1 = 9n + 1

                                                                                                   x = 9n +1 - 5n -1

                                                                      Answer:                x= 4n

Solve the following inequality: 10t + 7 , 200 > 21 , 000
Alla [95]

Answer:

t > 1380

Step-by-step explanation:

Subtract 7200 from both sides

Simplify

10t > 13800

Divide both sides by 10

10t/10 > 13800/10

Simplify

t > 1380

igomit [66]

Answer:

A) 1:4

Step-by-step explanation:

#We first calculate the campus' area:

a=lw\\\\=\frac{1}{4}\times \frac{1}{2}\\=0.125 \ mi^2

#We then calculate the campus' map area in square ft:

A=lw\\\\=0.5 \times 1\\\\=0.5 ft^2

Ratio is a comparison between two dimensions:

Ratio=\frac{0.125}{0.5}\\\\=0.25\\\\=\frac{1}{4}\\\\=1:4

Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4
