Sorry if this is a lot. It’s true of false. If n = 8, then 8 (n - 7/3n) equals 1/3. True or false?

If n = 1.5 then 6n - 2(n + 8) equals 14. True or false?

If n = 1, then 10 (5 -n) + 5n^2 equals 45. True or false?

If n = 2, then 4n^3 - n + 16 equals 14. True or false?

Please help this is ASAP I’ve been stressing out so much please respond.

1. false 2. true 3. true 4.false

Step-by-step explanation:

sorry, i can't understand your question. will later if you describe more clearly!

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
