Answer:

Box A= x+5

Box B= x+5

Box C= x+5

Step-by-step explanation:

So i was literally over here trying to big brain this problem, literally stressing like "Oh my gosh why is this so difficult wth is going on rn?!" when all i had to do was find the equation(which has been sitting on my paper for the last 15 minutes) and plug it in.

-_-

Chile anyways so the equation to the problem is 3(x+5) =20. And all you have to do is split the (x+5) into three parts on the tape diagram and it would all equal 20.

Answer:

x = 5

Step-by-step explanation:

The equality of bases property says powers of the same base will be equal if and only if the powers are equal. This property is used to solve exponential equations.

<h3>Application</h3>

$\dfrac{(2)^x}{2}=16\qquad\text{copy of the original equation}\\\\2\times\dfrac{(2)^x}{2}=2\times16\qquad\text{multiply by 2 to isolate the base}\\\\2^x=32\qquad\text{simplify}\\\\2^x=2^5\qquad\text{rewrite the constant as a power of 2}\\\\\boxed{x=5}\qquad\text{use the Equality of Bases Property}$

<em>Additional comment</em>

Equating the exponents is fully equivalent to taking the logarithm of both sides of the equation, to that base.

$\log_2(2^x)=\log_2(2^5)\ \Longrightarrow\ x=5$

Write following in y=mx+b form<br> 1/2 x-y= 4<br> 2y= x+ 6

Zigmanuir [339]

Lets do this.
$\frac{1}{2} *x-y=4$ /- $\frac{1}{2}x$
-y= $- \frac{1}{2}x+4$ /*(-1)
y= $\frac{1}{2}x-4$ - its the result

2y=x+6 /:2 (divide both sides by2 )
y= $\frac{1}{2} x+3$ - its the result
