Answer:
240 copies
Step-by-step explanation:
40/5 to find how many copies a minute.
You get 8 copies a minute.
Multiply 8 copies by 30 minutes to get 240 copies
She would need to play 50 minutes more to waste all her battery. In total 80 minutes.
Answer:
−5 < x < 10
Step-by-step explanation:
Add 1 to each part of the three parts of the inequality:
-6 +1 < x - 1 +1 < 9 +1
-5 < x < 10 . . . . . simplify
_____
The only place where there's an x is in the middle section. The only operation performed on x is subtraction of 1. To undo that subtraction, you add 1, but you must add 1 to all sides of the comparison symbols in order to keep them true.
Such a compound inequality is the same as the two inequalities:
Solving either one of these is done by adding 1 to both sides of the < symbol:
You can put these back together in the form of the compound inequality ...
-5 < x < 10
Answer:
Angle 1: 127
Angle 2: 153
Step-by-step explanation:
First, let's find angle 1 by finding the angle that's supplementary to it.
To solve for it, we can set up an equation where the unknown angle and the other angles in the triangle it's in add up to 180:
x+95+32=180
x=53
Since angle 1 is supplementary to 53, that means that angle 1 is equal to 180-53 = 127.
Then, to find angle 2, we can find the angle that's supplementary to it.
To solve for that, we can set up an equation where that unknown angle and the other angles in the triangle it's in add up to 180:
26+127+x = 180
x = 27
Since angle 2 is supplementary to 27, that means that angle 2 is equal to 180-27 = 153.
