Answer:

  n = 245/36

Step-by-step explanation:

Usually, these are solved in 2 steps:

  1. eliminate fractions by multiplying by the LCM of the denominators
  2. divide by the coefficient of the variable.

Doing that, we have ...

  (49n)(36/49) = (49n)(5/n)

  36n = 49·5 = 245 . . . . . simplify

  n = 245/36 . . . . . divide by the coefficient of n

_____

Another way to do these is to rewrite the proportion with both sides inverted:

  49/36 = n/5

Now, all you need to do is multiply by 5.

  n = 5(49/36) = 245/36

__

Or, you can do both of the original steps at the same time:

  (49n/36)(36/49) = (49n/36)(5/n)

  n = (49·5)/36 = 245/36

Zinaida [17]
The answer if I am correct should be C. 6, since if you divide forty-eight by two you get twenty-four. Twenty-four divided by four equals six, and twenty-four divided by three equals eight, eight is the number that would be the remaining amount of days. Hope this helps you and have an amazing day!

Answer: y=3/2x

Step-by-step explanation:

First, to find the equation, we can figure out that the cost depends on how many tickets are bought. We can use cost as our y and # of tickets as our x.

An equation in slope intercept form is as follows:

y=mx+b

To get our slope, we must figure out the relationship between the cost and the number of tickets, or the y and the x.

We can use the slope formula, \frac{y2-y1}{x2-x1}, to find the slope, m.

\frac{3-6}{2-4} = \frac{3}{2}

Thus, the slope of the equation is 3/2, making our final equation be y=3/2x.

the ratio of the measures of the sides of a triangle is 21:8:14. if the perimeter of the triangle is 215 ft, find the length of
Anestetic [448]

Answer:

see explanation

Step-by-step explanation:

the perimeter is the sum of the 3 sides of the triangle

add the parts of the ratio 21 + 8 + 14 = 43

divide the perimeter by 43 to find the value of one part of the ratio

\frac{215}{43} = 5 ft ← 1 part of the ratio, hence

21 parts = 21 × 5 = 105 ft

8 parts = 8 × 5 = 40 ft

14 parts = 14 × 5 = 70 ft

the 3 sides of the triangle are 105 ft, 40 ft and 70 ft

Which is the function represented by the table? A 2-column table with 4 rows. Column 1 is labeled x with entries negative 2, neg
Serggg [28]

Answer:

f(x)=4x

Step-by-step explanation:

Given: See the attached image

To find: the function represented by the table

Solution:

A function is a relation in which every element of the domain has a unique image in the co-domain.

f(-2)=-8=4(-2)\\f(-1)=-4=4(-1)\\f(0)=0=4(0)\\f(1)=4=4(1)

Here, -2,-1,0,1 are elements in the domain and -8,-4,0,4 are elements in the co-domain.

Therefore, the table represents the function f(x)=4x
