The jackson family is putting down flooring in part of their basement. the floor in this part of the basement measures 10 feet wide by 20 feet long. the flooring that they want to use costs $2 per square foot. how much will the flooring cost in all? explain

10x20x2=$400

All you have to do is find the area of the floor(10x20=200),then you just multiple the area by the cost(200x$2=$400),and that is how you find the cost.

step-by-step explanation:

i think because what else can be a sample of every member

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
