U move 12, then it will become 52-12=4w (do u know why it bcme -12? Bcz if you move positive it will become negative. And if you move negative, it will become positive) then it would b like this 40=4w and bring over your 4 become 40/4=w (its multiply so u bring over it become division) and the ans is 10. Hope you understand me:)) and u plot 10 on ur no. line :>
You can use permutations when order matters and use combinations when order doesn’t matter.
Answer:
X = 6
Step-by-step explanation:
Subtract 1 x from both sides so the equation will be 3x = 18. Then divide 3x by 3 and 18 by 3 to get 6
Answer:
13 inches
Step-by-step explanation:
Let P(t) and P(s) be the perimeters of the equilateral triangle and square respectively. Similarly, t and s be the side lengths of equilateral triangle and square respectively.
According to the first condition :
(Perimeter of an equilateral triangle is 11 inches more than the perimeter of a square)
According to the second condition :
(The side of the triangle is 6 inches longer than the side of the square)
From equations (1) & (2)
3(s + 6) = 4s + 11
3s + 18 = 4s + 11
3s - 4s = 11 - 18
-s = - 7
s = 7 inches
Thus the side of the triangle is 13 inches long.
