(3x+2)-(2x-2)
3x+2-2x-2
3x-2x=x
2-2+0
X
Answer:
-4
Step-by-step explanation:
Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.
So to solve for x, set 28 and 10x+68 equal to each other.
28=10x+68
First, subtract 68 from both sides
-40=10x
Then, divide both sides by 10
-4=x
If you want to check your answer plug -4 back into the original equation.
28=10(-4)+68
28=-40+68
28=28, which is true, therefore -4 is correct.
$650. You start with finding how many square feet the floor and the tiles are. 40x50=2000 square feet for the floor and 2x2=4 square feet for the tile. You then take 2000/4=500 to get the amount of tiles that you will need. After that, you take 500/10=50 to get the number of packages you will need. The final step is taking 50x13=$650 to get the total cost
