Solve the proportional<br> equation below:

Katarina [22]

Answer:

C. $p=\frac{-2}{3}$

Step-by-step explanation:

$\frac{p}{2}=\frac{p-2}{8}$

both side times by 8

$8\times ( \frac{p}{2})=8 \times (\frac{p-2}{8})$

$4p=p-2$

both side subtract with p

$4p-p=p-2-p$

$3p=-2$

both side divide by 3

$p=\frac{-2}{3}$

4 Celeste uses 24 inches of ribbon from a spool that holds 36 inches of ribbon. Which shows equivalent representations for the p

kaheart [24]

We are given that 24 out of 36 inches of ribbon is used. The percentage that is used is equivalent to:

$\frac{24}{36}=\frac{2}{3}$

Therefore, the percentage is:

$\frac{2}{3}\times100=0.66\times100=66\text{ percent}$

Evaluate the following expression (-3)^-2

OleMash [197]

<h3>Answer: the fraction 1/9</h3>

It is approximately equal to 0.1111

=================================

To get this answer, we use the rule

$x^{-k} = \frac{1}{x^k}$

The negative exponent tells us to apply the reciprocal to get the exponent to be positive.

So,

$(-3)^{-2} = \frac{1}{(-3)^2}\\\\(-3)^{-2} = \frac{1}{9}$

Squaring -3 means you square the negative as well

$(-3)^2 = (-3)*(-3) = 9$

The measure of <1 = 20x + 21 and the measure of <2 = 30x - 29.

geniusboy [140]

Answer:

Both equal 121 degrees

Step-by-step explanation:

Vertical angles are equal, and and 2 are indeed vertical angles. They are the "top" and "bottom" of the x formed. So you can use this.

angle 1 = angle 2

20x + 21 = 30x - 29

50 = 10x

5 = x

So just plug this in.

20x + 21

20(5) + 21

121

30x - 29

30(5) - 29

121

So both are 121.
