Answer:

\huge\boxed{\sf x = -7}

Step-by-step explanation:

<em>Let the number be x </em>

So,

=> The sum of number and 15 is x + 15

=> Three times will be 3(x+15)

<u>Given that</u> it equals 24

<u>So, the given condition is:</u>

3(x+15) = 24

<em>Resolving Parenthesis</em>

3x + 45 = 24

<em>Subtracting 45 to both sides</em>

3x = 24 - 45

3x = -21

<em>Dividing both sides by 3</em>

x = -7

Which graph shows a set of ordered pairs that represent a function?
Yuri [45]

Make XY tables for each option.

If any of the Tables have identical X numbers it is not a function.

The first option has two X's that re 2, so is not a function.

Second option has 2 x's that are 4's, so is not a function.

The third option has no repeating X values so is a function.

The fourth option has two -2's and two 0's so ids not a function.

The function is the third choice:

On a coordinate plane, solid circles appear at the following points: (negative 3, 2), (negative 2, 2), (0, 1), (1, 3), (2, negative 4), (4, negative 1).

Two ice skaters started on opposite ends of a 200-foot-long rink and then skated toward each
SSSSS [86.1K]

Answer:

The proportion that can be used to find x is;

(200-x)/x = 7/6

Step-by-step explanation:

Now, we want to find the proportion which can be used to find x.

From the question, we are told that the father skater traveled 7 ft for every 6 ft of the slower skater;

this means that the ratio of their speed is 7:6

Now, when they passed each other , the slower skater has traveled x ft, what this means is that the faster skater will have traveled a distance of (200-x) ft at that moment they passed each other.

Mathematically, since their time is equal i.e the time they used to pass each other, then, the ratio of their distances is same as the ratio of their speeds;

Hence;

(200-x)/x = 7/6 or x/(200-x) = 6/7
