Answer:
I think it's 12 or 12/1
Step-by-step explanation:
so you will use y2-y1
over x2-x1
then you subtract and there's your answer
and sometimes you have to simplify
Answer:
A greater percentage of blue T-shirts were sold.
see the explanation
Step-by-step explanation:
we know that
To find out the percentage sold, divide the number of shirts sold by the total number of shirts and multiply by 100
so
<em>White t-shirts</em>
total shirts 200
shirts sold 120
<em>Blue t-shirts</em>
total shirts 300
shirts sold 240
Compare
therefore
A greater percentage of blue T-shirts were sold.

Let s represent the measure of the second angle.
The measure of the first angle is 15° less than the second, so we can represent the first angle by (s-15).
The measure of the third angle is 45° more than half the second, so we can represent the third angle by (45+(s/2)).
The sum of these angles is 180°, so we can represent the sum as
... (s-15) + s + (45+s/2) = 180
Collecting terms, we have
... 2.5s +30 = 180
... 2.5s = 150 . . . . . . subtract 30
... s = 150/2.5 = 60 . . . . divide by the coefficient of s
The first angle is 60-15 = 45.
The second angle is 60.
The third angle is 45+60/2 = 75.
_____
<u>Check</u>
The sum of the three angles is 45 +60 +75 = 180.
