I cleaned 6/9 of my room, And my friend cleaned 2/9 of my room. How much of much of my room do we still have to clean?
Shtirlitz [24]

1/9 is the answer


9/9 is your whole room, and a total of 8/9 were cleaned (the total of you and your friends work) so do 9/9 - 8/9 = 1/9

Can you show work for all of these and match them
Ksenya-84 [330]

I'll show you how to do one of the equations and one of the inequalities. All the others are done exactly in the same way: you'll only have to change the numbers, and it will be a good exercise.

Equations

Let's take the first equality as an example: we have

|x-2|=5

By definition, the absolute value of a number is the positive version of that number: if the number is already positive the absolute value doesn't change it; if a number is negative the absolute value changes its sign.

So, if the absolute value of a number is 5, than that number was already 5, or it was -5, and the absolute value changed it to positive 5.

So, the solutions are given by

|x-2|=5 \iff x-2=5 \lor x-2 = -5 \iff x=7 \lor x=-3

Inequalities

Again, we'll use the first one as example. We have

|x+4|\geq 7

By the same logic as before, the absolute value of a number is greater than 7 if the number is already greater than 7, or if it is smaller than -7. For example, we have |-10|=10>7.

So, we have

|x+4|\geq 7 \iff x+4 \geq 7 \lor x+4 \leq -7 \iff x \geq 3 \lor x \leq -11

Instead, if we have an inequality with the "less than" sign, we have for example

|x-5|\leq 8 \iff -8 \leq x-5 \leq 8 \iff -3 \leq x \leq 13

Prav is converting £257 into $. He knows that £1 = €1.11 and €1 = $1.22. How many $ will Prav get? Give your answer to 2 dp.
Ostrovityanka [42]

Answer:

$348.03

Step-by-step explanation:

£257 = €1.11 * 257

£257 = €285.27

€285.27 = $1.22 * 285.27

€285.27 = $348.0294

Round to 2 dp, $348.03
