Hat is the solution to the equation 3/3(4c + 16)=2c+9 ?<br><br> c =
marusya05 [52]
If it is \frac{3}{3(4c+16)}=2c+9, go to AAAAAA
if it is (\frac{3}{3})(4c+16)=2c+9, go to BBBBB

AAAAAAAAA
\frac{3}{3(4c+16)}=2c+9
\frac{1}{4c+16}=2c+9
times 4c+16 to both sides
1=(2c+9)(4c+16)
distribute
1=8c^2+68c+144
minus 1 both sides
0=8c^2+68c+143
use quadratic formula
c=\frac{-17- \sqrt{3} }{4} or \frac{-17+ \sqrt{3} }{4}




BBBBBBBBBBBB
(3/3)(4c+16)=2c+9
1(4c+16)=2c+9
4c+16=2c+9
minus 2c both sides
2c+16=9
minus 16 both sides
2c=-7
divide both sides by 2
c=-7/2
c=-3.5





if it is \frac{3}{3(4c+16)}=2c+9,
c=\frac{-17- \sqrt{3} }{4} or \frac{-17+ \sqrt{3} }{4}


if it is (\frac{3}{3})(4c+16)=2c+9, c=-3.5

Which value of w makes 14=11+w/8 times 6 a true statement?
Vlad [161]

Answer: For the value of w=4, 14=11+\frac{w}{8}\times 6 is a true statement.

Step-by-step explanation:

Since, the given expression,

14=11+\frac{w}{8}\times 6

=  14=11+\frac{6w}{8}

=  14=11+\frac{3w}{4}

= 3=\frac{3w}{4} ( by subtraction property of equality)

⇒ =\frac{w}{4} ( By division property of equality)

⇒ w=4 ( By multiplication property of equality)
