3.the sum of twice a number and 14 less than the number is the same as the difference between 38 and the number. what is the number?
4. some number is six more than eight. what is the number?
5. 3.2x + 5.6x = 3.1 + 32.1
6b+1+4b=3b+6
6b+4b+3b=61
b=5
I think that's right. If its wrong someone correct me.
that's what I got too!!
I need to get my math homework done snd it is plotting figurse on a coordinate grid and it due on october 12 2006 and that TOMMROW !
Please do not use my name to do your work.
Ok, so post a new question and we'll see if we can help.
You're asked
Solve
1.6b+1+4b= 3b+6
Rearrange the b's to get and add 1 to each side to get
6b + 4b + 3b = 6  1 or
7b6b=5 so b=5
2.8x  4x = 8
This is (84)x=8 or
4x=8 now divide both sides by 4 to solve for x.
3.the sum of twice a number and 14 less than the number is the same as the difference between 38 and the number. what is the number?
Then 2x + (x14) = 38  x
So 3x  14 = 38  x
adding x and 14 to both sides you get
4x = 24 now divide both sides by 6
(Hopefully I read the problem correctly.)
4. some number is six more than eight. what is the number?
So x = 8 + 6
5. 3.2x + 5.6x = 3.1 + 32.1
Combine the x's to get
8.8x=35.2 then divide both sides by 8.8 to get x.
No, I'm not...and who are you supposed to be?
Look funny guy, learn to spell. There's only one l in DrPhil. Got it?

__________

how about this....... the area of a circle with radius is given by the formulaA=pie times radius to the 2nd power
make a table of values for A ,as radius increase from 0 to 10 units
I think DrBob went through this with you already. To make the table put 0 to 10 down the left side, r, r^2 and A at the top. Then calculate the area for each value.
It looks like
r...r^2...A=pi*r^2
0...0....pi*0
1...1....pi*1
2...4....pi*4
3...9....pi*9
Now finish the square for 4 to 10 and find the areas.

Solve
1.6b+1+4b= 3b+6
Move the bs to one side and numbers to the other side. Change sign when changing sides.
6b+4b+3b=61. Now combine terms.
6b+7b=5
b=5
2.8x  4x = 8
Just combine terms and solve for x. Post your answer here if you want us to check it.
3.the sum of twice a number and 14 less than the number is the same as the difference between 38 and the number. what is the number?
4. some number is six more than eight. what is the number?
let X = the number
X=8 + 6
Solve for X.
5. 3.2x + 5.6x = 3.1 + 32.1
Combine terms.
8.8X = 35.2
This give you 8.8X. You want to solve for X. Just divide both sides by 8.8
8.8X/8.8 = 35.2/8.8
X = ??
I hope this helps get you started.
