The opposite of -2/5

Well, the opposite would just be everything switched around!

So, our negative would become a positive, and the 5 and 2 would be switched around! :)

So, with the negative turned into a positive and with the numbers switched around, our answer is :

A) 5/2


What is I -10 I  ?

Well, the absolute value of something is basically just the distance of that number from 0.

So, if you were to plot -10 on a number, and then counted the numbers it took to get back to 0, it would be 10!

So, the absolute value of -10 is 10


Simplify : 3x² + I -4 I

First, we find the absolute value of -4.

An easier way to find the absolute value of something is to just take out the negatives, and switch it with a positive! So, if you are looking for the absolute value of a negative, simply turn it into a positive. However, if you are looking for the absolute value of a positive, it stays positive.

So, the absolute value of -4 is 4.

So, now we have : 

3x² + 4

Because you only asked for this simplified, this is the simplest it can be simplified.

~Hope I helped!~

The parents' club will need 100 of the same item for international night. They have a budget of $250. The choices are 100 baseba
Nuetrik [128]

Answer:

The parents' club can afford to buy 100 Baseball hats or 100 sports bottles.

Step-by-step explanation:

Given:

Item to be bought = 100

Total Budget = $250

Cost of each Baseball Hat = $2.45

Cost of each sports bottles = $2.50

Cost of each flag = $2.75

We need to find which items can they afford to buy.

Solution:

each Baseball Hat = $2.45

100 Baseball Hat = Cost of 100 Baseball Hat

Using Unitary method we get;

Cost of 100 Baseball Hat  = 2.45\times 100 =\$245

each sports bottles = $2.50

100 sports bottles = Cost of 100 sports bottles

Using Unitary method we get;

Cost of 100 sports bottles  = 2.5\times 100 =\$250

each flag = $2.75

100 flags = Cost of 100 flags

Using Unitary method we get;

Cost of 100 flags  = 2.75\times 100 =\$275

Hence from above we can see that;

Cost of 100 Base ball hat and 100 sports bottles are within the budget while Cost of 100 flags exceed the budget.

So we can say that;

The parents' club can afford to buy 100 Baseball hats or 100 sports bottles.
