-np - 70 < 40
-np < 40 + 70
-np < 110
-np/-p < 110/-p
n < 110/-p
4w - 7k = 28
4w-4w-7k = 28 - 4w
-7k = 28 - 4w
-7k/-7 = 28-4w /-7
k = 28-4w/-7
In one month, there are on average 30 days.
So if he talks 135 minutes per month, he talks on average 135/30 minutes per day
135/30 = 4.5
So on average he talks to his grandfather for 4 minutes and 30 seconds a day.
I’m pretty sure the equation would be
2x + 13 < 3x - 2
1 one and 58 hundredths.
I hope you like this answer, and have a good night and life! :D
"of" means multiply and "is" means equal
1.
x = 14
x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>
x = 42
2.
x = 14
x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>
x = 70
3.
x = 14
2x = 14(5) <em>multiply both sides by 5 </em>
2x = 70
x = 35 <em>divide both sides by 2 to isolate "x"</em>
4.
x = 14
7x = 14(8) <em>multiply both sides by 8 </em>
7x = 112
x = 16 <em>divide both sides by 7 to isolate "x"</em>
