HELP, I need help finding the value!

65

Step-by-step explanation:

1*5*2 + -1*0*-3 + 3*2*1 - -3*5*3 - 1*0*1 - 2*2*-1 =

10 + 0 + 6 + 45 - 0 + 4 =

65

see attached picture, that shows the recipe to do the other one.

why can't you?

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
