Kevin is three years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel.

GarryVolchara [31]

Answer:

I believe that Kevin is 6 years old now.

Step-by-step explanation:

I used the guess and check method to figure this out.

First, I began by making Daniel 1 years old, two years ago. Kevin was 4 times as old as Daniel two years ago, so he would be 4 at the time. Now, Daniel would be 3 and Kevin would be 6 years old. The statement that Kevin is three years older than Daniel would confirm this, because 6-3=3. Hope this helps, this is my first time answering:)

Which is the best estimate of the product of the fractions? StartFraction 4 Over 7 EndFraction times StartFraction 8 Over 9 EndF

Lapatulllka [165]

Answer:

Product = $\dfrac{64}{135}$

Step-by-step explanation:

The expression is as follows :

$\dfrac{4}{7}\times \dfrac{8}{9}\times \dfrac{14}{15}$

We need to find the product of the above expression

As 7 × 2 = 14

So, it will become :

$4\times \dfrac{8}{9}\times \dfrac{2}{15}\\\\=\dfrac{4\times 8\times 2}{9\times 15}\\\\=\dfrac{64}{135}$

So, the product of the given fractions is $\dfrac{64}{135}$ .

Answer:

Step-by-step explanation:

The quadratic formula would be the following...

$x = \frac{-b (+-)\sqrt{b^{2} - 4ac } }{2a}$

where the original quadratic equation would be represented as follows

$ax^{2} + bx +c = 0$

Using this information and the information provided in the image we can plug in the quadratic equation values in the image to form the quadratic formula.

$\frac{-(-20)±\sqrt{(-20)^{2} - 4(16)(-6) } }{2(16)}$
