Answer:

z = 15/30 = 3/6

Step-by-step explanation:

1/5z - 5/6 = - 4/5z - 1/3

1/5z + 4/5z = - 1/3 + 5/6

5/5z = - 2/6 + 5/6

5/5z = 3/6

z = 3/6 / 5/5

z = 3/6 * 5/5

z = 15/30

aksik [14]

Answer:

m1=12 and m2=168

Step-by-step explanation:

$m1 + m2 = 180 \: (straight \: angle) \\ then \\ x - 12 + 7x = 180 \\ 8x - 12 = 180 \\ 8x = 180 + 12 = 192 \\ x = 192\div 8 \\ x = 24\\ hence \\ m1 = 24 - 12 = 12 \\ m2 = 7 \times 24 = 168.$

70 - q - q - 2q = 80???

Aneli [31]

70-q-q-2q= 80

combine like terms first

so you get 70-4q= 80

subtract 70 on both sides and you get -4q= 10

divide -4 on both sides and you get q= 10/-4 or -2.5

Olegator [25]

Given :

Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.

To Find :

How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.

Solution :

Ratio of people smiled by total number of people is :

$R = \dfrac{36}{50}$

Now, it is given that we have to use the given conditions.

Therefore, ratio will be same :

$\dfrac{s}{650}=\dfrac{36}{50}\\\\s = \dfrac{36}{50}\times 650\\\\s = 468$

Therefore, number of smiles Nathan expect to return is 468.
