Answer:

x ≤ 4 OR x < 2.25

Step-by-step explanation:

a. Given 5x − 19 ≤ 1

5x ≤ 1 + 19

5x ≤ 20

Now, make x the subject of the formula, we have:

x ≤ 20/5

x ≤ 4

Therefore, given 5x − 19 ≤ 1, the solution is x ≤ 4

b. Given − 4x + 3 < − 6

− 4x < − 6 − 3

− 4x < − 9

Now, make x the subject of the formula, we have:

x < −9/−4

x < 2.25

Therefore, given − 4x + 3 < − 6, the solution is x < 2.25.

Conclusion:

The solution to solve for x in 5x−19≤1 OR −4x+3<−6 is x ≤ 4 OR x < 2.25

John is going camping, and he needs to buy a tent. The outdoor store has one that cost $90, but it's on sale for 25% off. What i

pochemuha

Answer:

Step-by-step explanation:

Okay so, im not the best at explaining, but so we have a percentage. its 25%. you want to take the 25% and put it over 100 because a percentage is a number or ratio expressed as a fraction of 100. so it will be written as 25%/100

divide 25 by 100 and you get 0.25, correct? so that's one step further towards the answer.

then we write x/90 because we don't know (well we do) what we're gonna put. but, we're gonna multiply 0.25 by 90 and we get 22.5, which is equivalent to 22.50.
