What do you suppose we might do first?

Q.10(1+3b)+15b=-20
tkhunny
  • tkhunny
Okay, writing the problem down is a good first step. Now what? Are we solving for b? You had better get all the 'b's on one side of the equation.
anonymous
  • anonymous
no
tkhunny
  • tkhunny
... and everything else on the other side.
anonymous
  • anonymous
so do u *
tkhunny
  • tkhunny
"no" what? We're not solving for b? I guess we'll need a problem statement. What are we doing?
anonymous
  • anonymous
we are doing distribute ,combine and solve
tkhunny
  • tkhunny
This is why you need to produce the ENTIRE problem statement and SHOW some work of your own. MUCH confusion can be avoided. Solve for what?
tkhunny
  • tkhunny
What's preventing your from doing that? Show the distributive property... 10(1+3b) = ?? Go!
anonymous
  • anonymous
40 becuase 1+3=4*10=40
tkhunny
  • tkhunny
Where did he b go? Please demonstrate the distributive property. Do NOT try to solve the whole problem. 10(1+3b) = ??
anonymous
  • anonymous
ok so first u solve the (1+3b) frist
Rushwr
  • Rushwr
10(1+3b) + 15b= -20 Resolve the bracket 10+30b + 15b= -20
anonymous
  • anonymous
so i just add
Rushwr
  • Rushwr
yep !
anonymous
  • anonymous
how did u get 30b
tkhunny
  • tkhunny
You still have not demonstrated the Distributive Property. a(b+c) = ab + ac That is what you do. Demonstrate: 10(1+3b) = ??
Rushwr
  • Rushwr
10*3b = 30b
anonymous
  • anonymous
what did u do with the 1
Rushwr
  • Rushwr
1*10 = 10
anonymous
  • anonymous
so it is 55
anonymous
  • anonymous
@Rushwr am i right
Rushwr
  • Rushwr
nop
tkhunny
  • tkhunny
lime. You're not listening. SHOW us how to apply the distributive property. Stop trying to jump to the end of the problem.

ok so tell me what i have to slove frist i need to know becuase ihave 6 to do befor i go to bed
Rushwr
  • Rushwr
it's like this 10(1+3b) = 10 x 1+ 10 x 3b = 10 + 30b now put it on to the equation 10+30b+15b = -20 From now onward you have to go in the normal method.
anonymous
  • anonymous
what is the normal method just adding
Rushwr
  • Rushwr
yep
Rushwr
  • Rushwr
u can only add the same type of numbers
anonymous
  • anonymous
sorry if i am giving u a hard time
Rushwr
  • Rushwr
no no just go ahead !
tkhunny
  • tkhunny
You should find the time to practice ONLY the Distributive Property. It will help you constantly if you are not struggling with it.
anonymous
  • anonymous
sorry if it is wrong i got 55
anonymous
  • anonymous
is it 35
Rushwr
  • Rushwr
okai now see 10+30b+15b = -20 right? now u add up the b parts 10+45b = -20 right? now take that 10 to the other side so we cann add -20 and 10 45b= -20-10 45b= -30 so b = -30/45 = -2/3 got it ?
anonymous
  • anonymous
got it
Rushwr
  • Rushwr
Awesome !!!!!!! ^_^
anonymous
  • anonymous
are we done
Rushwr
  • Rushwr
yes. so if u want to simplify it more divide -2 by 3 and u will get a value like -0.666
anonymous
  • anonymous
thank so much
