Answer:

Combine like terms

Subtraction property of inequality

Division property of inequality

Step-by-step explanation:

We are given tnat

75x+35\geq 7(11x+9)+4

We have to find the missing justification in given solution

75x+35\geq 7(11x+9)+4

Reason:Given

75x+35\geq 77x+73+4

Reason:Distributive property

75x+35\geq 77x+67

Reason:combine ike terms

-2x+35\geq 67

Reason:Subtraction property of order

-2x\geq 32

Reason:Subtraction property of inequality

x\leq -16

Reason:Division property of inequality

Answer:

(-4,1)

Step-by-step explanation:

The answer is just where the two lines intersect

I'm rather tired so double check me on this but I'm getting about (-4,1) and it's asking for an approximation so think (-4,1) is fine

There are 100 people in a wedding house, including children, men and women, and there are 100 pappadas to give with Sadya Te.
olga nikolaevna [1]

Answer:

Two possible sets of answers.

5 men, 11 women and 42 children, or

10 men, 2 women and 88 children

Selamat Sadhya!

Step-by-step explanation:

M = number of men

W = number of women

100-M-W = number of children

Total number of pappadas

5M+3W+(100-M-W)/2 = 100

Solve for W

W = (100-9M)/5 .......................(1)

Examine equation (1).

In order to have W as a whole number, M must be multiple of 5

Therefore M = 5 or 10

If M = 5, W = (100-45)/5 = 11 and children = 100-5-11 =  84

If M = 10, W = (100-90)/5 = 2 and children = 100-10-2 = 88
