Add 1 to both sides of the inequality to obtain;

x\:>\:5+1

x\:>\:6

Answer: 2. x\:>\:6, open dot at 6 and shaded to the right.(A)

QUESTION B.

The given inequality is 2x \le 6.

Divide both sides by 2;

x \le \frac{6}{2}.

x \le 3.

Answer: 5. x \le 3, closed dot at 3 and shaded to the left(B).

QUESTION C

The given inequality is x-7\:>\:-4

Add 7 to both sides to get;

x\:>\:-4+7

\Rightarrow x\:>\:3

QUESTION D

We want to solve;

-2x \:

Divide through by -2 and reverse the inequality sign;

x \:>\:\frac{6}{-2}

x \:>\:-3

Answer; 3. x \:>\:-3 Open dot at -3 and shaded to the right. (D)

QUESTION E

We have  

4\:

Divide through by -4 and reverse the sign.

\frac{4}{-4}\:>\:x

-1\:>\:x

or

x\:

Answer: 6. x\: open dot at -1, and shaded to the left(E)

QUESTION F

The given inequality is -2x+3\:

Add -3 to both sides to get;

-2x\:

-2x\:

Divide both sides of the inequality by -2 and reverse the sign;

The statement a (a symbol) b defined to be true if and if a/5&gt;b/3 Which of the following is true ?(here have three questions)
Alex_Xolod [135]

Answer:

9. C

10. C

11. C

Step-by-step explanation:

9.

simply, \frac{4}{5} >\frac{2}{3}

10.

the greatest divisor of 28 is 7, so:

28 + 7 = 35

11.

the greatest divisor of 15 is 5, so:

15 + 5 = 20

n = 20

the greatest divisor of 20 is 10, so:

20 + 10 = 30

Solve this −14(z−5)=−14z+70
Bas_tet [7]

Answer:

All real numbers are solutions.

Explanation:

−14(z − 5) = −14z + 70

[ Step 1: Simplify both sides of the equation ]

−14(z − 5) = −14z + 70

(−14)(z) + (−14)(−5) = −14z + 70 (Distribute)

−14z + 70 = −14z + 70

[ Step 2: Add 14z to both sides ]

−14z + 70 + 14z = −14z + 70 + 14z

70 = 70

[ Step 3: Subtract 70 from both sides ]

70 − 70 = 70 − 70

0 = 0

Therefore, all real numbers are solutions.
