the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements

Answer:

x ≈ 6

Step-by-step explanation:

The legs of an isosceles triangle are congruent , both 2x - 4 , then

x + 2x - 4 + 2x - 4 = 24 , that is

5x - 8 = 24 ( add 8 to both sides )

5x = 32 ( divide both sides by 5 )

x = 6.4 ≈ 6 ( to the nearest whole number )

       Minutes                          8              x

                                             3x = 15 * 8

                                               x = 15 * 8 / 3

                                               x = 120 / 3

                                               x = 40

Jackie has $33, and needs to get a taxi. The cost for a taxi is a fee of $5, plus $7 per mile. Which inequality would help Jacki
Rus_ich [418]

Answer:

5 + 7x \le 33

Step-by-step explanation:

Given

Base\ Charge = 5

Additional = 7 per mile

Total = 33

Required

Determine the inequality

First, we need to determine the total cost for x miles.

Cost = Base\ Charge + Additional * x

Cost = 5 + 7 * x

Cost = 5 + 7x

The total cost can not exceed the amount he has, so the inequality is:

Cost \le Total

5 + 7x \le 33
