Answer:

x=7/10

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+5=12−7x

Step 1: Simplify both sides of the equation.

3x+5=12−7x

3x+5=12+−7x

3x+5=−7x+12

Step 2: Add 7x to both sides.

3x+5+7x=−7x+12+7x

10x+5=12

Step 3: Subtract 5 from both sides.

10x+5−5=12−5

10x=7

Step 4: Divide both sides by 10.

10x10=7/10

x=7/10

Door is 77 inches high, 35.25 inches wide and 1,75 inches thick how much paint is needed

Leviafan [203]

If you wanted to paint the entire door (even the top and bottom which people don't usually paint)

the surface area is
SA=2(LW+LH+WH)
where L=length, W=width and H=height

given
L=35.25
W=1.75
H=77

SA=2(35.25*1.75+35.25*77+1.75*77)
SA=2(61.6875+2714.25+134.75)
SA=2(2910.6875)
SA=5821.375

you need enough paint to cover 5821.375 square inches of door
