Answer:
when both bottom numbers on a fraction are the same at the lowest form
Step-by-step explanation:
example: 2/4 + 6/8 the common denomenator is 8 as both numbers go into it and you only have to times by 2 so answer would be 10/8 which is also 1 2/8
Answer:
4i√5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Area = 1/2(b×h)
b = 18, h = 8
Area = 1/2(18×8)
Area = 18 × 4
Area = 72 square inches
Answer:
6 2/3 cups needed
Step-by-step explanation:
So first I would find the unit rate for cookies and cups
1 cup = 9 cookies
So now divide becuase we want to find the amount of cookies
60/9= 6.666666666 or 6 2/3
Now normally it would just be left like that
IF:
|1/2.x -2/3.y = 7 and
|a.x - 8.y = -1
have no solution, that means these 2 linear equations ARE PARALLEL (since they can never meet). Reminder: 2 equations are parallel if they have the same coefficient , so let write each of the equation in the normal form:
a)1/2.x -2/3.y = 7→ -2/3.y = -1/2.x + 7 → y = 3/4.x - 21/2
b) a.x - 8.y = -1 → - 8.y = -a.x - 1 → y= a/8.x + 1
a) and b) are // if (3/4) = (a/8), [the 2 coefficient OR the 2 slopes)
a/8 = 3/4 → a = 24/4 and a = 6 (Answer D)
