Materials + installation = $192.49

-Materials =<u> 132.49 </u>

Installation = $ 60.00

Installation cost = 1 skateboard/$15

No. of skateboards = 60.00 × 1/15

No. of skateboards = 4

Four skateboards will be repaired.

3(n-5)-2(n+8)=11 solve

Butoxors [25]

Answer:

n=42

Step-by-step explanation:

The first step is to open the brackets by multiplying the vale before the brackets to the values inside the brackets giving attention to the signs which gives:

3n-15-2n-16=11

Then we collect like terms together.

3n-2n-15-16=11

evaluating the above equation we get

n-31=11

n=11+31

=42

Plz help i dont want to fail

WINSTONCH [101]

Answer:

$p=\$1.50,\\c=\$0.75$

Step-by-step explanation:

We can write the following system of equations:

$\begin{cases}3p+2c=6.00,\\2p+3c=5.25\\\end{cases}$

Multiply the second equation by $-\frac{3}{2}$ to isolate and solve for $c$ :

$\begin{cases}3p+2c=6.00,\\-3p-4.5c=-7.875\\\end{cases},\\-2.5c=-1.875,\\c=\fbox{$\$0.75$}$ ,

Now plug in $c=0.75$ into any equation to solve for $p$ :

$3p+2(0.75)=6.00,\\3p=4.50,\\p=\fbox{$\$1.50$}$ .

Evaluate log(-13)<br> Correct answer will get brainliest

Sedaia [141]

if given log(a)=b, where no base is stated, we assume base 10, or $log(a)=log_{10}(a)$

also, $log_a(b)=c$ translates to/can be written equivilently as $a^c=b$

therefore, given

$log(-13)=?$ where we want to find ?

assume base 10 and translate

$10^?=-13$

since we cannot raise a positive number to any real power and give a negative number, ? is not a real number and therefore, there are no real solutions

if we do want to find a solution, we can use Euler's idendity

$e^{\pi i}=-1$ where i is the complex number i=√-1 and e is euler's number
