Answer:

The number line that shows x > 8

Step-by-step explanation:

First, subtract 15 from both sides

<em>15 + 2x -15 > 31</em>

<em>2x > 16</em>

Then divide both sides by 2

<em>2x ÷ 2 > 16 ÷ 2</em>

<em>x > 8</em>

One car rental company charges $30 per day plus $0.25 per mile driven. A second company changes $40 per day plus $0.10 per mile
EastWind [94]
30 + 0.25m > 40 + 0.10m
0.25m - 0.10m > 40 - 30
0.15m > 10
m > 10/0.15
m > 67 miles.....u would have to drive 68 or more miles for the second company to be less expensive

Zadania są na zdjęciach. Pls mam z tym czas do jutra!!!

p + 2 = 5 ==> p = 3

3p + 2 = p + 3 ==> 2p = 2 ==> p = 1

3k + 5 = 2k + 2 ==> k = -3 (niemożliwe; lewa strona wagi ma większą wagę)

2w + 10 = 4w + 7 ==> 2w = 3 ==> w = 3/2

d + 9 = 3d + 2 ==> 2d = 7 ==> d = 7/2

W drugim zadanie każda litera reprezentuje wagę jednego z obiektów. Na przykład 3k + 4 reprezentuje całkowitą wagę 3 kół i 4 ciężarów, każdy o wadze 1 kg.

Trzecie zadanie to tylko połączenie dwóch pozostałych.
