Answer:
D. Yes, because the remainder is 0.
The decrease was 3. (from 30 down to 27)
Always calculate the decrease as a percent of the ORIGINAL number.
3/30 = 0.1
To change a decimal to a percent, move the point 2 places that way ==> .
0.1 = 10% .
When you go from 30 to 27, that's a decrease of 10% .

Step-by-step explanation:
i think this might be the answer but if it not alseat I try helping
A+b+c= 180
<span>a = ?
</span><span>b = 2a - 10 (twice a minus 10)
</span><span>c = b + 25 (25 more than b)
</span><span>Substitute for b
c = (2a-10) + 25
</span><span>Now substitute back into a+b+c=180
a + (2a-10) + (2a-10+25) = 180
</span><span>Eliminate the parentheses
a + 2a - 10 + 2a - 10 + 25 = 180
</span><span>Combine like terms
5a + 5 = 180
</span><span>Subtract 5 from both sides
5a = 175
</span><span>Divide both sides by 5
a = 35
</span><span>Substitute into the equation for b.
b = 2a -10 = 2*35 - 10 = 70 - 10 = 60
</span><span>Add 25 to b to get c.
c = 60 + 25 = 85</span><span>Check by adding them up.
35 + 60 + 85 = 180
Done.</span>
