Answer:
= 165/8
Step-by-step explanation:
11/2hrs = 1/5
x = 3/4
then Cristcross
x = 33/7/1/5
x = 33/8 ×5
x= 165/8
Answer:
-10x^2 +9+8x^2-5x+7=-2x^2-5x+16
Answer:
estimate: $80
exact amount paid: $82
Step-by-step explanation:
If you round $246 to 240, then divide it by 3, you should get $80. The cost per pair should be around $80 each
For the exact answer you take the amount spent (246) and divide it by the amount of jeans she bought (3).
246/3 = 82
Answer:
<h2><u><em>
no solution, the equation is false</em></u></h2>
Step-by-step explanation:
what is the solution for the following equation 3(2x+3)=2(3x+4)?
3 * (2x + 3) = 2 * (3x + 4)
6x + 9 = 6x + 8
6x - 6x = -9 + 8
0 = ±1
the equation is false
Answer:
Step-by-step explanation:
Factor it by first setting it equal to 0:
Now subtract 9 from both sides:
Divide both sides by 4:
Then take the square root of both sides:
x = ±
, which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,
x = ±
is an equivalent radicand, we can now replace -1 with its imaginary counterpart:
x = ±
Each one of the elements in the radicand are perfect squares, so we simplify as follows:
x = ±
And there you go!
