Grandma has 14 red roses and 7 pink roses.how many more red roses than pink roses does she have?
pychu [463]
In the given question there are numerous important information's available. using these information's the answer can be easily deduced. The total number of red roses that Grandma has is already mentioned in the question and it is 14. The total number of pink roses that grandma has is also mentioned in the question and that is 7. Now this is a simple question and the required answer can be reached by simply subtracting the number of pink roses from the number of red roses.
The number of more red roses than pink roses grandma has = 14 - 7
                                                                                                   = 7
So Grandma has 7 more red roses than pink roses.

Find the distance between each pair.<br>A ( 2, -1) B ( -6 , 5 )<br><br>A.36<br>B.120<br>C.100
yuradex [85]

Answer:

B. 120  and C. 100   = 0.4 DIFFERENCE Between the two pairs.

Step-by-step explanation:

2/-1 =  -2

-6/ 5 = -1.2

the difference where we divide by  /2 is -1.2 - 2 = 0.8 / 2  = 0.4

0.4 divides into all options ABC however 36 it divides 9 times

120 it divides 30 times

and 100 is divides 25 times.

9/ 0.4 = 22.5 and is wrong

30 / 0.4 = 75

25 / 0.4 = 62.5 and is wrong

therefore B 120 is correct.
