6|6-4x|=8x+4<br> Need help solving the equation. I need help checking the extraneous solutions too.

Vsevolod [243]

$6|6-4x|=8x+4\\\\Formula\ for\ absolute\ value\\\\
|a|=a,\ for\ a \geq 0\\ or\\|a|=-a,\ for\ a \ \ -4x \geq -6\ \ -->\ \ \ x \leq \frac{3}{2}\\\\
6(6-4x)=8x+4\\
36-24x=8x+4\ \ |subtract\ 4\\
32-24x=8x\ \ | add\ 24x\\
32=32x\ \ | divide\ by\ 32\\
x=1\ \ \ and\ 1 \leq \frac{3}{2}\\\\
II\\
for\ 6-4x \ \ -4x < -6\ \ -->\ \ \ x > \frac{3}{2}\\\\
6(-6+4x)=8x+4\\
-36+24x=8x+4\ \ | subtract4\\
-40+24x=8x\ \ \ | subtract\ 24x\\
-40=-16x\ \ | divide\ by\ -16$ $x=2,5\ \ and\ 2,5>\frac{3}{2}\\\\Solutions:\\
x\in \{1;2,5\}$

A 5-pound bag of dog food costs $11.25. What is the unit price of the dog food in dollars per pound?

andreev551 [17]

Answer:

$2.25

5 lbs = $11.25

The unit price in this context means the price of a 1-pound bag of dog food so you would divide $11.25 by 5:

$11.25 ÷ 5 = $2.25

navik [9.2K]

75% of the teachers were first-year teachers

Step-by-step explanation:

the formula for percentage will be used for the problem

The percentage is given by:

$Percentage=\frac{Quantity}{Total}*100\\$

Here

Total teachers = 57+19 = 76

First-year teachers = 57

So,

$Percentage\ of\ first\ year\ teacher = \frac{57}{76}*100\\=0.75*100\\=75\%$

Hence, 75% of the teachers were first-year teachers
