Answer: <em>Please note the number of the order may differ.</em>

n_1  = 18

n_2 = 9

Step-by-step explanation:

     We will write mathematical equations to represent the situation. Let n_1 be the first number and n_2 be the second.

-> The sum of two numbers is 27.

n_1 + n_2 = 27

-> One number is 2 times as large as the other.

n_1  = 2 * n_2

     Now, we will solve it as a system of equations.

n_1 + n_2 = 27

(2 * n_2) + n_2 = 27

3 * n_2 = 27

n_2 = 9

-----------

n_1  = 2 * n_2

n_1  = 2 * (9)

n_1  = 18

For what value of x is f(x) = 10?<br> (-1,6)(2,8)(3, 10) (5, 16)
Alex_Xolod [135]

Answer:

(3,10)

Step-by-step explanation:

From f(x)=10 you can see that the value of y,which is equal to f(x), is 10.

Therefore, the only option you could pick is that where y=10,which is the case for option (3,10).

A line with a slope of 0 passes through the point (9,5). What is its equation in slope-intercept form?
shepuryov [24]

Answer:

y = 5      

Step-by-step explanation:

Any line with a slope of 0 is horizontal, represented by the equation y = a number. That number is the y-value of all the points the line intersects.

We know that that the line intersects (9,5). So, take the y-value of that point and write it into the equation of y = a number. Thus, the answer is y =5.

How do you write mixed numbers or fractions as decimals?
aksik [14]
To write fractions as decimals divide the numerator by the denominator, for example 3/4 3 divided by 4 equals 0.75 so 3/4 as a decimal is 0.75. If you want to do that with a mixed number, 3 3/4 3 divided by 4 equals 0.75 then add the 3 so 3 3/4 is equal to 3.75.
