Evaluate each expression.
(14 - 2) ÷ (5 + 3(-2 + 1))

Step-by-step explanation:

(14-2) =12

(5+3(-2+1))= 5+3(-1)) =5+(3×(-1))

= 5+(-3) =5-3=2

Substitute the values if the expressions above into the original expression

(14-2)÷(5+3(-2+1)) = 12÷2 =6

tangent

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
