16x − 7 ≤ − 71 Find the solution set of the inequality

natka813 [3]

Answer:

x $\leq -4\\$

Step-by-step explanation:

Add 7 to other side making equation 16x $\leq$ -71+7

16x $\leq$ -64

16 goes into -64 -4 times.

Answer would give you x $\leq$ -4

To check, you could substitute -4 into the inequality

16(-4)-7 $\leq$ -71

-71 $\leq$ -71 check

16(-10)-7 $\leq$ -71

-167 $\leq$ -71 check

Solve 3(b-5) = 27

Sergeu [11.5K]

Step-by-step explanation:

♤ 3(b-5) = 27

=> 3b - 15 = 27

=> 3b = 27 + 15 = 42

=> b = 42/3

=> b = 14 (Ans) 

♤ 2x/3 = 6

=> 2x = 6 × 3 = 18

=> x = 18/2

=> x = 9 (Ans) 

♤ 2(n + 5) = 15

=> 2n + 10 = 15

=> 2n = 15 - 10 = 5

=> n = 5/2

=> n = 2.5 (Ans)

♤ a + a + a + a = 24

=> 4a = 24

=> a = 24/4

=> a = 6 (Ans)

♤ 4c + 6 = 18

=> 4c = 18 - 6 = 12

=> c = 12/4

=> c = 3 (Ans)

Khan question, please help

barxatty [35]

Answer:

Step-by-step explanation:

Khan gives you right answer and tells you what's wrong, but this site is for help so, all you need to do is use the destructive property.

12 x 2= 24 12 x 3 = 36 12 x -1 = -12

now you have the original expression, 24 + 36 - 12 (without the letters.)
