When you must multiply non whole numbers, decimals are easier to manipulate in the sense that setting up a multiplication problem with decimals rather than fractions is much simpler and easier to calculate.

What expression is equivalent to 3-(-2+5)
maxonik [38]

Answer:

Ok ok, I see. So the answer is -9.

Step-by-step explanation:

We know the expresion is:

-3(-2+5)

We need to distrubute the -3 to what is in the parthese.

When I say distribute, basically you need to multiply the numbers inside the parethese by -3. So we can think of it as:

-3*-2=6

and:

-3*5=-15

Which we can rewrite as:

(6-15)

Subtract 15 from 6 and you get -9:

6-15=-9

Sorry hope this helps!

Section 1:

using this format we can determine what the answer is:

42 105
—— • ——-
100 x

(the spacing may be off but imagine two separate fractions)

first multiply 100 by 105 to get 10,500

then divide by 42 to get 250

this means that sasha’s book has 250 pages

section b:

using the same formula we can solve this problem:

first we need to multiply 250 by 2 to get the total cost of both tickets

175 x
—— • ——
100 500

(again spacing may be off but think of two separate fractions)

then multiply 500 by 175 to get 87,500

then divide by 100 to get 875

to find the profit subtract 875-500

this means he will make $375 profit

conclusion:

sasha’s book has 250 pages

trevor will make $375 profit

this is the method my teacher taught me last year so it should be right, hope this helps and please mark brainliest!!
