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

Mathematics
1 answer:
GarryVolchara [31]3 years ago

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:)

Answer:

Slope: 2

a: 5

b: 6

y-coordinate when x = 0: -2

Step-by-step explanation:

To find the slope, you need to divide the change in the y values between two points on a line by their change in x values. The two complete points given are (6, 10) and (2, 2), so doing this for them would be...

(10-2)/(6-2) = 8/4 = 2, so your slope is 2

To find a, you must use this slope by counting from one of the points. For every one you go to the right, you go up two. So, how many times do you need to go up 2 (slope), from 2 (starting point's y coordinate), to get to 8 (target point's y coordinate)? (8-2)/2 = 6/2 = 3, so 3 times. Add that to 2 (starting point's x coordinate) to get 5, so a is 5.

To find b, you can just use (6, 8). You know you're going to the LEFT one, so you must go DOWN 2. Subtract 2 from 8 to get 6.

For the last question, do the same with (2, 2). You're going LEFT 2, so you're going DOWN 4. Subtract 4 from 2 to get -2.

Let me know if you need a more in-depth explanation on any part of this!

Free_Kalibri [48]

Answer:

21 = n

Step-by-step explanation:

5 - \frac{1}{3}n = -2

-5 - 5

________________

-⅓<em>n</em> = -7

____ __

-⅓ -⅓

21 = <em>n</em>

* Dividing by a fraction is the exact same as multiplying by its <em>multiplicative</em><em> </em><em>inverse</em>:

\frac{-7}{-\frac{1}{3}} = -7 \times -3 = 21

A regular six sided die and an eight equal segment spinner, numbered 1 to 8, are rolled/spun simultaneously. What are the odds i
kirill [66]

Answer:

1/3

Step-by-step explanation:

In statistics, the probability of both an event A and an event B happening is equal to the probability of A happening multiplied by the probability of event B happening.

Let's say spinning a prime number is event A and rolling a number ≤ 4 is event B.

There are 8 possibilities on an eight equal segment spinner, and there are 4 prime numbers between 1 and 8 (including 8), which are 2, 3, 5, and 7. This means that the probability of spinning a prime number is 4/8, or 1/2

There are 6 possibilities on a die, and there are 4 possibilities of rolling a 4 or less (1, 2, 3, 4). Therefore, the probability of rolling 4 or less on a die is 4/6, or 2/3

The probability of both of these happening can be calculated by multiplying these together, so 1/2 * 2/3 = 2/6 = 1/3
