Answer:

  x ≥ 16  or  x < 0

Step-by-step explanation:

You want ...

  (x -4)/x ≥ 3/4

  4(x -4) ≥ 3x . . . . . . multiply by 4x (requires x > 0)

  4x -16 ≥ 3x

  x ≥ 16 . . . . . . . . . . add 16-3x

__

For x < 0, multiplying by 4x gives ...

 4(x -4) ≤ 3x

  4x -16 ≤ 3x

  x ≤ 16 . . . . . and x < 0

__

There are two sets of solutions:

  x < 0  or  x ≥ 16

Answer:

0.8 miles in a minute, which would be 40 miles a hour.

Step-by-step explanation:

2/5 = 0.4

0.4 times 2 = 0.8

30 seconds times 2 = 60 seconds or 1 minute

60 times 0.8 = 40

60 times 1 minute = 60 minutes or 1 hour

40 miles in an hour or known as 40 miles a hour.

Answer:

p = 7

Step-by-step explanation:

set the expressions = to each other

4(n+7) = 4(n+p)

distribute the 4 on both sides(multiplying the numbers on the inside)

4n+28 = 4n+4p

subtract the 4n from the right and left

28 = 4p

divide by 4

p = 7

Answer:

[tex]11-x^2[/tex]

Step-by-step explanation:

"11 less than the square of a number" can be written as an algebraic inequality as → 11 < x².

An inequality compares two numbers or expressions. For example, we can write -

2x + 3 > 5

2x + 9 < 1

Given is the mathematical statement as -

" the square of a number is greater than 11"

We can write the mathematical statement as an algebraic inequality as follows. Let the number be {x}. We can write -

11 < x²

Therefore, "11 less than the square of a number" can be written as an algebraic inequality as → 11 < x².

Answer:

Equation: n=3m; Bob needs to read 51 novels over 17 months.

Step-by-step explanation:

Since the number of novels Bob needs to read (n) depends on the amount of months (m) we can say that n is the dependent variable and m is the independent. Since x is always independent and y is always independent we can say that m is going to stand for x and n is going to stand for y. Each month Bob reads 3 novels so we can write the equations as n=3m. To find out how many books he needs to read in 17 months plug it into the equation. n=3(17) -------------------> n=51

Total calories in  4 grams of fat, 3 grams of protein and 3 grams of carbohydrate is 56

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: 4 grams of fat, 3 grams of protein and 3 grams of carbohydrate

Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

Thus total calories from given diet is = 4×4+4×3+9×3

                                                             =16+12+27

                                                            =56

Hence, Total calories in  4 grams of fat, 3 grams of protein and 3 grams of carbohydrate is 56
