la edad de josé y beatriz están en la relacion de 5 a4 . si dentro de 3 años la suma de ambas edades seran 60 años , ¿ cual es la edad de beatriz ?

Answers

Answer:

La edad actual de Beatriz es de:

30 años

Step-by-step explanation:

Planteamiento:

5e = 4b

(e+3) + (b+3) = 60

e = edad actual de José

b = edad actual de Beatriz

Desarrollo:

de la segunda ecuación del planteamiento:

e + b + 6 = 60

e + b = 60 - 6

e + b = 54

e = 54 - b

sustituyendo este último valor en la primer ecuación del planteamiento:

5(54-b) = 4b

5*54 + 5*-b = 4b

270 - 5b = 4b

270 = 4b + 5b

270 = 9b

b = 270/9

b = 30

e = 54 - b

e = 54 - 30

e = 24

Comprobación:

5e = 4b

5*24 = 4*30 = 120

Solve for f.
Round your answer to 2 decimals.
9f = {(12f – 2)

Answers

Answer:

f=0.67

Step-by-step explanation:

Let's solve your equation step-by-step by isolating f.

9f=12f−2

Step 1: Subtract 12f from both sides.

9f−12f=12f−2−12f

You get:

−3f=−2

Step 2: Divide both sides by -3.

−3f/−3 = −2/−3

You get:

f= 2/3, or f= 0.67

What is the sum of the measures of the interior angles of an octagon? Enter your answer in the box.

Answers

So, 360/8 = 45 degrees each time. The internal angle is 180-45=135. And 8*135=1080. The sum of the interior angles of a polygon is (n - 1)180, where n is the number of sides.

The sum of interior angles of an octagon will be 1080°.

We have a Octagon.

We have to find the sum of the measures of the interior angles of a pentagon.

What is Octagon ?

In geometry, a Octagon is a eight - sided polygon.

According to the question, we have - A Octagon.

The formula for finding sum of the measures of the interior angles of a polygon is = ( n - 2) x 180°. The number of triangles in each polygon is two less than the number of sides.

The formula for calculating the sum of interior angles is:

For a Octagon - n = 8.

Therefore - the sum of interior angles of an octagon will be -

(8 - 2) x 180

180 x 6

1080°

Hence, the sum of interior angles of an octagon will be 1080°.

solve for y. 3[y-13]=12

Answers

Answer:

y = 17

Step-by-step explanation:

3(y-13)=13

3y-39=12

3y=51

y=17

Answer:

y = 17

Step-by-step explanation:

3[y-13] = 12

3*y + 3*-13 = 12

3y - 39 = 12

3y = 12 + 39

3y = 51

y = 51/3

y = 17

In the adjoining figure, GP bisects angle BGH and HP bisects angle GHD. calculate the size of angle a.​

Answers

Answer:

90°

Step-by-step explanation:

AB and  CD are parallel lines and EF is reversal

Therefore angles BGH and DHG are consecutive interior angles

As we know the sum of consecutive interior angles equals to 180°:

∠BGH + ∠DHG = 180°

Line GP bisects angle BGH , therefore

m∠PGH = 1/2*m∠BGH

Line HP bisects angle GHD, therefore

m∠PHG = 1/2*m∠GHD

Sum of two angles of triangle GHP:

m∠PGH + m∠GHD = 1/2(∠BGH + ∠DHG) = 1/2*180° = 90°

Therefore the missing angle a is:

∠a = 180° - (m∠PGH + m∠GHD) = 180° - 90° = 90°

The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)
