Answer:
In the last task, the result is 17+3x/6
Step-by-step explanation:
X+5/3 - 2x-7/6 + x/2
2(x+5)-(2x-7)+3x <em>/</em><em>6</em>
2x+10-2x+7+3x <em>/</em><em>6</em>
17+3x/6
I dunno this task above, I hope this one is correct :))
When you are solving an algebraic one-step equation, the goal is to isolate the variable on one side of the equal sign, two-step equations are the same, but with one more step (hence the name)
Answer:
36 tiles
Step-by-step explanation:
First, find area of the square floor knowing the formula as;
Area= 
where s= side of a square.
If one side of the floor is 12 feet, then Area= 
Next, find the area of each tile using the same formula and given s=2 feet;
Area(tile) = 
To find the number of tiles needed to cover entire floor, divide area of the floor by area of one tile; 144 / 4 = 36 tiles
Answer:
4x+18
Step-by-step explanation:
Length = x+3+x+3
width = x+3-x= 3
perimeter = x+3+x+3+x+3+x+3+3+3=4x+18
