Answer:

x= 0 and x = -4

Step-by-step explanation:

The first step for absolute value equations is to isolate the expression contained within the absolute value bars:

3|2 x+4|-1 = 11

3|2 x+4| = 12

|2 x+4| = 4

So |2 x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.

2 x+4 = 4

AND

2 x+4 = -4

Solve both of those two step equations and you'll get

So 0 and -4 are your solutions

The price of a flight was increased by 3% to £650. What was the price before the increase?
liubo4ka [24]

Answer:

£ 631

Step-by-step explanation:

Hi this is a simple mathematics issue.

First, let's imagine what is 3%. '3 percents' means 3/100. If your family have 100 apples and you have 3 apples, that means you have 3% of your family apples.

Now, get back to this problem. We need to find the price before increase. Let's say the price was £ X. Now we will find the X number.

It's said that the price was increased by 3%. That means they took 3% of X and added that amount to X to have the new price : £ 650. That means we have this equation :

650 = X + 3%×X

Let's make it easier to look :

650 = X + 3/100 ×X

650 = X×( 1+ 3/100)

= X × 103/100

So we can see 650 is equaled to X multipled by 103/100.

To find the correct answer, simply divide 650 by 103/100.

*A hint: When you divide a number by a fraction, you can simply put the number multiplied by the "flipped" fraction .

Hope you learn with Joy and High Grades !!!

A number is chosen at random from 1 to 25. Find the probability of selecting an odd number or multiples of 5. *
Ymorist [56]

Answer:

Odd number: 13/25 (52%)

Multiples of 5: 5/25 (20%)

Step-by-step explanation:

There are 13 odd numbers between 1 and 25 so you have a 13/25 chance which is 52% (13/25 = 0.52). There are 5 multiples of 2 between 1 and 25 so you have a 5/25 chance which is 20% (5/25 = 0.2).
