Here is the algebraic solution:

T is the tens digit

O is the ones digit

T+O = 14

So O = 14 - T <---- this is the first equation

The original number is 10*T + O

If the digits are reversed the original number is increased by 18.

The number if the digits are reversed is:

10*O + T = 10*T + O + 18

10*(14-T) + T = 10*T + (14-T) + 18 <--- substitutes O with 14-T per first equation above in bold

140 - 10T + T = 10T + 14 - T + 18 <--- distributive left side

140 - 9T = 9T + 32

140 = 9T + 9T + 32

140 - 32 = 9T + 9T

108 = 18T

108/18 = T

T= 6

THe tens digit is 6.

The ones digit must be 8.

Reversing 86 - 68 = 18

The original number is 68.

Answer:

Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.

So, k2. When you add Kim's age to her sister age you get 30.

Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 30. Now let's solve it.  

k2 + k = 30 < Given

3k = 30 < Combine like terms

k = 10 < Divide both sides by 3

We know Kim's sister is 10 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 10 for k and you get 10(2) = 20

Kim's sister is 10 y/o and Kim is 20 y/o

Answer:

How many more times x does the giraffe need to be fed?

a) 17 times

Write your answer as an inequality

Let x represent the number of feedings left.

1/3(75 - 24) ≤ x

= (25 - 8) ≤ x

= 17 ≤ x

Step-by-step explanation:

A large male giraffe needs to eat at least 75 pounds of food each day.

At each feeding, the giraffe is fed 3 pounds of food.

Hence,

3 pounds of food = 1 feeding

75 pounds of food =

= 75/3

= 25 feedings.

That means in a day, the giraffe is fed 25 times.

The giraffe has already consumed 24 pounds of food. How many more times x does the giraffe need to be fed?

3pounds of food = 1 feeding

24 pounds of food =

Cross Multiply

= 24/3

= 8 feedings.

From the calculation here, the cloth has already fed the giraffe 8 times

Hence,

= 25feedings - 8 feedings

= 17 Feedings left.

Hence, the giraffe has 17 Feedings left to go.

Write your answer as an inequality

Let x represent the number of feedings left.

1/3(75 - 24) ≤ x

= (25 - 8) ≤ x

= 17 ≤ x

Step-by-step explanation:

[tex](x^3-(\frac{x}{2})^2 +x) + (x^2-\frac{x}{4} -5)[/tex]

The addition sign between the sets of parentheses means to add the two equations together by combining like terms

There is only one term raised to the 3rd power so that remains the same.

Next you have -1/2x ^2 + x ^2 = 1/2x ^2

Then x + -x/4 = 3/4x

And -5 is the only term with no variable so that remains the same.

Now combine into one line:

X ^3 +1/2x^2 + 3/4x -5

A function is a rule that determines the relationship between one variable and another. If we have a variable which we input into the relationship and gives a unique value for the other variable, the input value is the independent variable while the output is the dependent variable.

For an expression to be function, we must have a unique value of output for every value of input.

Answer:

2/3

Step-by-step explanation:

The slope of the line can be calculated by dividing the vertical distance (rise) by the horizontal distance (run) between the two points.

The first point has coordinates (-1,0), and the second point has coordinates (2,2).

The rise is 2-0=2, and the run is 2-(-1)=3. Therefore, the slope is 2/3.

the ans is 0.72, your answer is 479.20

Step-by-step explanation:

The solution to the given decimal division is calculated as: 479.17

To divide decimals, we need to convert both numbers to a simple unit and divide to get:

345.00/0.072

We know that 0.072 can be written as:

0.072 = 72 * 10⁻³

345.00 can be written as:

345.00 = 34500 * 10⁻²

Thus, we have:

(34500 * 10⁻²)/(72 * 10⁻³)

= (34500/72) * (10⁻²/10⁻³)

= 479.17 * 10

= 479.17
