To find the least number of rows she can make will be found by finding the biggest way to divide these into equal groups (greatest common factor).
You can use prime factorizations of each number to find the gcf.
150 - 2 x 3 x 5 x 5
360 - 2 x 2 x 2 x 3 x 3 x 5
The common prime numbers are 2 x 3 x 5
You can make 12 (360/30) rows of pink and 5 (150/30) rows of red.

Answer:
1/2
Step-by-step explanation:
It is a independent problem. Flipping a head the first time will not affect the other results therefore it is still one half.
Answer: After 4 months they will have the same number of Stamps
Xian and Kai will have 124 stamps each one.
Step-by-step explanation:
60+16x = 76+12x (Subtract 12 from both sides)
-12 -12
60+4x = 76 (Subtract 60 from both sides)
-60 -60
4x/4x = 16/4x (Divide 16 by 4)
X = 4
Answer:
see explanation
Step-by-step explanation:
(1)
x + 20 and 45 are vertically opposite angles and are congruent, so
x + 20 = 45 ( subtract 20 from both sides )
x = 25
Similarly 5y and 135 are vertically opposite angles and are congruent
5y = 135 ( divide both sides by 5 )
y = 27
(2)
x + 30 and 70 are vertically opposite angles and are congruent, then
x + 30 = 70 ( subtract 30 from both sides )
x = 40
Similarly y + 50 and 110 are vertically opposite and congruent , so
x + 50 = 110 ( subtract 50 from both sides )
x = 60
