Answer:
She must score 90 points
Step-by-step explanation:
Find the average of the first 2 tests
76 + 80 = 156
Divide the sum of the first 2 tests by how many tests there were
156 ÷ 2 = 78
Multiply 82 by 3
82 x 3 = 246
Subtract 156 from 246
246 - 156 = 90
Add all the numbers together to get the average
90 + 80 + 76 = 246
246 ÷ 3 = 82
Hope this helps!
We know that
• Lashonda purchased a prepaid phone card for $20.
,
• Long-distance calls cost 8 cents a minute.
,
• The remaining credit on her card is $17.12.
This problem can be expressed as
Where <em>x</em> is the number of minutes.
We solve the equation for <em>x</em>
Then, we divide by -0.08 the equation
<h2>Therefore, Lashonda's call last 36 minutes.</h2>

I'm pretty sure that all of the Prime numbers only have two factors. Let's say 3 for an example.
Step-by-step explanation:
The number 3 only has the factors of 3 and 1.
The two factors are itself (of course) and 1 (any number can go into one).
Another way to do this if you had to find out an answer like this.
3x1=3. Any number that can go into itself times 1 has only 2 factors.
Or at least I think. This is probably wrong. So Sorry if it is.
