The fraction would be 997/1000, since this decimal goes to the thousandths place.
2 7/8 + 2 3/8= 4 10/8, which equals 5 2/8, which is also equal to 5 1/4
A.
If you multiply the original equation by 3 you get -45x+3y=54, which is the exact same as A, therefore they have infinite solutions.
Answer:
20 units
Step-by-step explanation:
Since the triangle is equilateral then all 3 sides are equal in length.
Equate any 2 sides and solve for x
4x = 3x + 5 ( subtract 3x from both sides )
x = 5
hence
4x = 4 × 5 = 20
3x + 5 = (3 × 5) + 5 = 15 + 5 = 20
7x - 15 = (7 × 5) - 15 = 35 - 15 = 20
The lengths of the sides are 20 units
