Insert a parenthesis 5+2*9-3=42

5 + 2 * 9 - 3 = 42

Right now there is an imaginary parentheses around (2 * 9) because you always solve multiplication first.

If we put a parentheses around (5 + 2), the answer would be:

7 * 9 - 3 = 60

If we put a parentheses around (9 - 3), the answer would be:

5 + 2 * 6 = 17

If we put parentheses around (5 + 2) and (9 - 3), the answer would be:

7 * 6 = 42

Your answer is: (5 + 2) * (9 - 3) = 42

Since, we are given

5+2*9-3=42

We know that

7*6=42

we can also write it as

(5+2)*6=42

(5+2)*(9-3)=42

so, we can insert parenthesis this way

and we get

(5+2)*(9-3)=42.............Answer

Tom has 28 milk chocolates and emily has 24 dark chocolates they have to divide these chocolates into small packets that each ha
Nutka1998 [239]
28+24=52
So we make a sum of what's going to equal 52 in small packets.
I found 4x13=52. 13 would be the number of packets......
BUT!! Since it MUST be equal dark and milk and we have 28 and 26,
you would have to eliminate 1 pack because all 4 would be milk chocolate.
So that is only 12 packets.
4 per pack so that would be 2 dark and 2 milk per packet.

If f is a function and x is an element in its domain, which statement is true about the graph of f?
Arada [10]
An appropriate choice among these is
  The graph of f is the graph of the equation y = f(x).

_____
Horizontal and vertical axes of the Cartesian plane are conventionally labeled and referred to as "x" and "y", respectively. When we talk about the graph of f(x) in that context, we usually mean the graph of y=f(x). However, this convention may not be followed in all cases. There may be no "y" label on the graph at all, or the horizontal axis may be labeled something other than "x".
