is this true or false (90+856)b 20=80 true or false

OpenStudy (ryanwhite499):

Why is b there or does it belong there

OpenStudy (minimato):

Yea I was just about to ask is that b supposed to be there

OpenStudy (ryanwhite499):

If it doesn't... we know that (90+856)(20) dose not equal 80.... if we solve it, it will give us 18920... so its flase

OpenStudy (ryanwhite499):

If it does... then we have to solve this completely... (90+856)(b)(20)=80 Step 1: Simplify both sides of the equation. 18920b=80 Step 2: Divide both sides by 18920. 18920b 18920 = 80 18920 b= 2 473 Answer: b= 2 473

OpenStudy (ryanwhite499):

And it will still be flase
