If Alexa's mom paid 1/2 of the $450:
$65

if Alexa's mom paid 1/2 of the remaining price:
$145


Alexa's mom paying 1/2 the $450:

$450 divided by 2 = $225
$225 - $120 = $105
$105 - $40 = $65
Alexa has $65 left to pay


Alexa's mom paying 1/2 of the remaining price after the student discount and Alexa payed $120:

$450 - $120 = $330
$330 - $40 = $290
$290 divided by 2 = $145

(hope this helped )

What is the cube root of 27a^12
tino4ka555 [31]

ANSWER

3{a}^{4 }

EXPLANATION

The cube root of

27 {a}^{12}

is

\sqrt[3]{27 {a}^{12} }

This is the same as:

(27 {a}^{12} )^{ \frac{1}{3} }

( {3}^{3} ({a}^{4})^{3}  )^{ \frac{1}{3} }

=  (3{a}^{4} )^{3 \times  \frac{1}{3} }

= 3{a}^{4 }

Would you solve the equation 0.25x + 7 = 1/3x – 8 <br> using fractions or decimals? Explain please.
mamaluj [8]

Answer:

x = 180

Step-by-step explanation:

Solve the value of x :

0.25x + 7 = \frac{1}{3}x - 8

-Combine \frac{1}{3}x and 0.25x by subtracting 0.25x by \frac{1}{3}x :

0.25x - \frac{1}{3}x  + 7 = \frac{1}{3}x - \frac{1}{3}x  - 8

-\frac{1}{12}x + 7 = -8

-Subtract 7 on both sides:

-\frac{1}{12}x + 7 - 7 = -8 - 7

-\frac{1}{12}x = -15

-Multiply both sides by -12, the reciprocal of -\frac{1}{12} :

\frac{-\frac{1}{12}x}{-\frac{1}{12}} = \frac{-15}{-\frac{1}{12}}

x = -15 (-12)

x = 180

Therefore, the value of x is 180.
