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>
1000 + 450(36)
1000 + 16,200 = 17,200.
He payed $17,200 for the car.
Hope this helps!
105,159 to the nearest ten-thousandth ...
^^ ok 1 is the ten thousandth so is 0 bigger or smaller than 4? No.
So your answer would be 100.000.
5000 + 7000 = 12000
5 x 10^4 + 7 x 10^4 = 12 x 10^4
