5(2q-8)\geq7\\10q-40\geq7\\10q\geq47\\q\geq4.7

so the solution is not really a single number but a range, depending on how q is defined. I am assuming q is defined in domain of Real numbers, and then the solution to the inequality will be "all real numbers larger or equal to 4.7"

Answer:

1. 5 is a solution to the inequality

2. 8 is a solution to the inequality

3. q=20 is a possible solution to the inequality

4. t=28 is not a possible solution to the inequality

Step-by-step explanation:

1.

1+f<7

subtract 1 from both sides of the inequality;

f<7-1

f<6

The value of f should therefore be strictly less than 6. From the alternatives given only the number 5 meets this condition and is thus a solution to the inequality.

2.

g-3>4

add 3 to both sides of the inequality;

g>4+3

g>7

The value of g should therefore be strictly greater than 7. From the alternatives given only the number 8 meets this condition and is thus a solution to the inequality.

3.

q-2>16

add 2 to both sides of the inequality;

q>16+2

q>18

The value of q should therefore be strictly greater than 18. Consequently, q=20 is a solution to the inequality since;

20>18

4.

t-7<10

add 7 to both sides of the inequality;

t<10+7

t<17

The value of t should therefore be strictly less than 17. Consequently, t=28 is not a solution to the inequality since;

28 is not less than 17.

Solve the equation x – 5 = 0.1(x + 5) for x
AlexFokin [52]

Answer:

Step-by-step explanation:

x - 5 = 0.1(x +5)

x - 5 = 0.1x + 5*0.1

x -5 = 0.1x + 0.5 {Add 5 to both sides}

  x = 0.1x + 0.5 + 5

  x = 0.1x + 5.5

x -0.1x = 5.5      {subtract 0.1x from both sides}

  0.9x =5.5         {Divide both sides by 0.9}

        x = 5.5/0.9

       x = 55/9

       x = 6 1/9
