Roman numbers* XCIX = LV _ XXXIII

XI

i need to know what signs go where is it "+ +" or "- +"

or "+ -" or "- +" ???

The sign that go in the expression is - "+ +"

Step-by-step explanation:

Given - XCIX = LV _ XXXIII  _ XI

To find - i need to know what signs go where is it "+ +" or "- +"  or "+ -" or "- +" ???

Proof -

We know that from the table that,

XCIX = 99

LV = 55

XXXIII  = 33

XI = 11

So,

The equation becomes

99 = 55 _ 33 _ 11

Now,

If we put + + then the equation becomes

99 = 55 + 33 + 11

⇒99 = 99

It satisfies.

Now,

If we put - + then the equation becomes

99 = 55 - 33 + 11

⇒99 = 33

It does not satisfies.

Now,

If we put + - then the equation becomes

99 = 55 + 33 - 11

⇒99 = 77

It does not satisfies.

So,

The sign that go in the expression is - "+ +"

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
