Answer:

Step-by-step explanation:

You will have to use the PEMDAS rule here. so Parntheses goes first, then exponents, then mutiplicaton or division, and finally addition or subtraction.

20-7= 13

-2^2 = (-2 * -2) = 4

9/3 = 3

so... 13*3 = 39+4 =43

Greetings!

This can be solved by creating a simple equation.
$1/4+1/6+x=1$

Solve for x.
$1/4+1/6+x=1$
Find the LCM.
$3/12+2/12+x=1$
$5/12+x=1$
Add -5/12 to both sides.
$(5/12+x)+(-5/12)=(1)+(-5/12)$
Simplify.
$x=1/1-5/12$
Find the LCM.
$x=12/12-5/12$
$x=7/12$

He kept 7/12 of the raisins for himself.

Hope this helps.
