Basically you will group the b together. so 4b+7b would be 11b (you add the coefficients aka the first numbers) together. since 5 cannot be grouped w anything else, you leave it. your final simplified answer would be 11b+5

Fred buys a binder for $4.50 and six reams of paper. Latasha buys an ink cartridge for $17.50 and four reams of paper. Both spen

kondor19780726 [428]

Answer:

The the price of one ream of paper is $6.5.

Step-by-step explanation:

Here, Let us assume the cost of one ream of paper = $ m

<u>The money spent by Fred:</u>

The money spent on a binder = $4.50

The money spent on 6 ream of papers = 6 x ( cost of 1 ream )

= 6 x ($m) = 6 m

⇒The total money Fred spent = Money spent on (binder + 6 ream of papers)

= 4.50 + 6 m ....... (1)

<u>The money spent by Latasha:</u>

The money spent on a cartridge = $17.50

The money spent on 4 ream of papers = 4 x ( cost of 1 ream )

= 4 x ($m) = 4 m

⇒The total money Latasha spent = Money spent on (cartridge + 4 ream of papers)

= 17 .50 + 4 m .... (2)

Also, Both spend the same amount of money

⇒4.50 + 6 m = 17 .50 + 4 m ( from (1) and (2))

or, 6 m - 4 m= 17. 50 - 4, 50

or, 2 m = 13

or, m = 13/ 2 = 6.5

So, the value of m = $6.5

Hence, the the price of one ream of paper is $6.5.

Which of the following could be used to calculate the area of a sector in the circle shown below

lara [203]

Answer:

Therefore the Last option is correct

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

Step-by-step explanation:

Given:

Radius = r = 8 in

θ = 42°

To Find:

Area of Sector = ?

Solution:

We know that

$\textrm{Area of Sector}=\pi (Radius)^{2}\times \frac{\theta}{360}$

Substituting the given values in the formula we get

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

Which is the required Answer.

Therefore the Last option is correct

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

. Ana tiene el triple de edad que su hijo Jaime. Dentro de 15 años, la edad de Ana será el doble que la de su hijo. ¿Cuántos año

poizon [28]

Answer:

La madre de Jaime tiene 30 años más que él.

Step-by-step explanation:

Llamemos x a la edad actual de Jaime, si la edad actual de Ana es el triple que la de Jaime, entonces la edad actual de Ana es 3x.

Dentro de 15 años, la edad de Jaime será x+15 (edad actual más 15 años) y usando el mismo razonamiento, la edad de Ana será 3x + 15.

Por otro lado el problema nos dice que dentro de 15 años, la edad de Ana (que ya sabemos que será 3x + 15) será igual al doble de la que tendrá su hijo en 15 años. Esto en forma de ecuación se representa:

$3x+15=2(x+15)$ (la edad de Ana será igual que el doble de la de su hijo)

Resolviendo la ecuación:

$3x+15= 2(x+15)\\3x+15=2x+30\\3x-2x=30-15\\x=15$

Por lo tanto, Jaime tiene 15 años y su madre tiene $3x=3(15)=45$ años. Por lo tanto la diferencia de edad es de 30 años y Ana tiene 30 años más que su Jaime.
