Answer:

93 hot dogs

Step-by-step explanation:

Make a system of equations

Let x represent hamburgers and y represent hot dogs

x+y=124

y=3x

Substitute 3x in for y

x+3x=124

Combine like terms

4x=124

Divide by 4 on both sides

x=31

There were 31 hamburgers, sold, so plug 31 back in the first equation

31+y=124

Subtract 31 on both sides

y=93

So, 93 hot dogs were served

Hope this helps! :)

Please help me!<br> Hint: the number is negative

wel

Answer:

$-36$ goes into the box

Step-by-step explanation:

Let the number be $x$ , then

$(m^x)^{\frac{1}{3}}=m^{-12}$

We now use the following property of exponents to simplify the left hand side of the equation.

$(a^m)^n=a^{mn}$

This implies that;

$m^{x\times \frac{1}{3}}=m^{-12}$

$\Rightarrow m^{\frac{x}{3}}=m^{-12}$

Since the bases are the same, we equate the exponents to get;

${\frac{x}{3}=-12$

We now multiply both sides by 3 to get;

$\frac{x}{3}\times 3=-12\times 3$

$\Rightarrow x =-36$

Therefore the number that goes into the box is $-36$
