Okay. Basically, a is greater than or equal to 9.
First, you do distribute the 2.
8a+2-10a(< or =)20
Subtract two on both sides.
8a-10a(< or =)18
Then subtract 10a from 8a
-2a(< or =)18
Divide by two on both sides
and switch around the greater than sign since you divided by a <span>-2
</span>a(> or =)-9
<span>And if you check, -9 works, -8 works, and -10 doesn't work.</span>
Answer:

Hope this helped ..
Answer:
c = b -d/a
Step-by-step explanation:
a(b-c)=d
Divide each side by a
a(b-c)/a = d/a
b-c = d/a
Subtract b from each side
b-c-b = d/a -b
-c = d/a -b
Multiply each side by -1
c = -d/a+b
c = b -d/a
24.9/150* 100%= 16.6%
16.6% of 150 is equal to 24.9~
