My grade in my Intergrated Science II is 88.4% and I have an assignment that is 60 points and is based upon completion. What would be my grade if I didn't turn it in.​

the barter

i think its a and d

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

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
