What is the solution of 2m=-6n-5 when n=1,2,3

Mathematics
1 answer:
Travka [436]3 years ago
7 0

Answer:


Step-by-step explanation:

Simplifying

2m + -6n + 5n + 3m = 0


Reorder the terms:

2m + 3m + -6n + 5n = 0


Combine like terms: 2m + 3m = 5m

5m + -6n + 5n = 0


Combine like terms: -6n + 5n = -1n

5m + -1n = 0


Solving

5m + -1n = 0


Solving for variable 'm'.


Move all terms containing m to the left, all other terms to the right.


Add 'n' to each side of the equation.

5m + -1n + n = 0 + n


Combine like terms: -1n + n = 0

5m + 0 = 0 + n

5m = 0 + n

Remove the zero:

5m = n


Divide each side by '5'.

m = 0.2n


Simplifying

m = 0.2n

y = 2x

Step-by-step explanation:

The linear functions are given by:

y = mx+b

To find the slope, we have to find the change in x and y

The change in x is:

-14-(42) =-14+42 =28\\14+14= 28

The change in y is:

-28-(-84) = -28+84 = 56\\28-(-28) = 28+28 = 56

The slope is:

Slope = \frac{change\ in\ y}{Change\ in\ x}\\=\frac{56}{28}\\= 2

Putting slope in equation of linear function

y =2x+b

To find the value of b, we will put any pair of input and output in the slope-intercept form

So, putting (14,28)

28 = 2(14) + b\\28 = 28+b\\b = 28-28\\b = 0

Hence,

the linear equation for function is:

y = 2x

Grandma received 0.25 liters of medicine from her doctor. The directions asked her to take one teaspoonful 3 times daily until i
kupik [55]

Answer:

Dec 10

Step-by-step explanation:

0.25 liter = 250 ml

4 ml * 3 = 12 ml

250/12 = 20.83 days

Nov 20 - Nov 30: 11 days

Dec 1 - Dec 9: 9 days

On December 9, she can still take her 3 doses.

By December 9, she will have taken 12 ml per day for 20 days for a total of 240 ml. She has 10 ml left for Dec 10th.

On Dec 10, she will take 2 doses of 4 ml and 1 dose of 2 ml, and she will finish the medicine.
