Use the three steps to solve the problem.

Flauer [41]

The two numbers are 8,13.

Step-by-step explanation:

Let,

smaller number = x

Larger number = x+5

According to given statement;

Smaller number + Bigger number = 3x-3

$x+(x+5)=3x-3\\x+x+5=3x-3\\2x+5+3=3x\\8 = 3x-2x\\8=x\\x=8$

Smaller number = 8

Larger number = 8+5 = 13

The two numbers are 8,13.

Makovka662 [10]

Levant will receive about 9 american dollars when he exchanges his pesos.

According to this question, 1 american dollar is worth about 11 pesos. In order to find that, you need to divide 3000/270 which gives you around 11. In order to find out how many dollars he will receive for his pesos, you need to divide 100 by 11 which gives you about 9 dollars.

In the figure below, BD and AC are diameters of circle P.

Answer:

$arc\ DC=30^o$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

The point P is the center of the circle (the drawing is not a scale )

step 1

Find the measure of angle ∠CPD

we know that

$m\angle CPD+150^o=180^o$ ---> by supplementary angles (form a linear pair)

$m\angle CPD=180^o-150^o=30^o$

step 2

Find the measure of arc DC

we know that

<u><em>Central angle</em></u> is the angle that has its vertex in the center of the circumference and the sides are radii of it

$arc\ DC=m\angle CPD$ ----> by central angle

therefore

$arc\ DC=30^o$

Please help me. I don’t know how to do this I really need this answer.

Ainat [17]

The answer is c.
I will explain

p - 2r = q

1. Move variable to the right by adding it’s opposites on both sides

p - 2r + 2r = q + 2r

2. Eliminate the opposites (-2r and +2r)

p = q + 2r
