Answer:
<u>8 inches of wire can be bought for 36 cents.</u>
<u>8 inches of wire can be bought for 36 cents.Step-by-step explanation:</u>
if 16 inches of wire cost 36 cents, just divide 64 by 2 (which gives you 32) so now that you divided 64 by 2, divide 16 by 2 (which is 8)
The answer is b
(-1,3,5)
Hope this helps!
Answer:
28
Step-by-step explanation:
x = 2 point questions, y = 3 point questions
x + y = 40
2x + 3y = 92
Solving this we get x = 28, y = 12 so the answer is 28.
Answer:
Step-by-step explanation:(206-3x)+x
2(3x)+x+12
ok as i think one no is statsfy this equation .
The first equation is x = -1
The second and third equations are no solution
The third equation is all rel numbers.
We can tell each one by solving them. In the first one, you get the following.
4 + x = -8x - 5 ----> Add 8x to both sides
4 + 9x = -5 ----> Subtract 4 from both sides
9x = -9 ----> Divide both sides by 9
x = -1
For the middle two, when you attempt to solve, you get untrue statements. This shows there are no solutions. See the example below.
7 + 2x = 2x - 7 ----> Subtract 2x from both sides
7 = -7 (UNTRUE)
And for the last one, each term cancels out, which shows that we have all real solutions.
-3x + 3 = 3( 1 - x) ----> Distribute the 3
-3x + 3 = 3 - 3x ----> Add 3x to both sides
3 = 3 (TRUE)
