Which of the following represents the solution to the inequality 2 | 5 - 2x | - 3 ≤ 15
Oksanka [162]

Answer:

[-2,7] is the solution of inequality .

Step-by-step explanation:

Given :  inequality 2 | 5 - 2x | - 3 ≤ 15

To find: solution of inequality.

Solution : We have given that 2 | 5 - 2x | - 3 ≤ 15 .

On adding 3 both sides:

2 | 5 - 2x | - 3+3 ≤ 15 +3

2 | 5 - 2x |  ≤ 18.

ON dividing both side by 2 and simplify

| 5 - 2x |  ≤ 9.

On applying absolute rule,  if | u | ≤ a,a>  then -a ≤ u≤ a

-9≤5 - 2x ≤ 9.

5 - 2x ≤ 9                 ,    5 - 2x ≤ -9.

- 2x ≤ 9-5

- 2x ≤ 4

On dividing by -2

x ≥ -2.

For  5 - 2x ≤ -9.

 - 2x ≤ -9-5

- 2x ≤ -14

On dividing by -2

x ≤ 7

Therefore ,  [-2,7] is the solution of inequality .

1/4 (dot) 3/5 simplifily
stich3 [128]

Answer: 1/20 (fraction) or 0.05 (decimal)

Step-by-step explanation:

first i like to make them a decimal so its easier.

1/4 = 0.25

1/5 = 0.2

multiply 0.25 and 0.2 = 0.05

make 0.05 a fraction

1/20

simplify. (it's already in its simplest form)

the answer is 1/20 as a fraction or 0.05 as a decimal.

(i dont know which one ur teacher wants u to do fraction or decimal?)
