the anser to that problem is -1/3
Answer:
1 7/8
Step-by-step explanation:
3/8 * 5/1 = 15/8
<-- First multiply 3/8 by 5
----------------------------------------------
15/8 = 1 with a remainder of 7
<-- Then convert 15/8 to a mixed number by dividing 15 by 8
15/8 = 1 7/8
Answer:
95 times
Step-by-step explanation:
Probability of rolling a 5 =1/6
So no. of times 5 is expected when the number cube is rolled out 570 times = 570*1/6 = 95 times
Answer:
Number n increased by 18 = n +18
Number is 2 less than 5 times n= 5n -2
They are same => n +18 = 5n -2
Option B
[ n + 18 = 5n -2
18 +2 =5n - n
20 = 4n
n = 5
Lets check 5+18 = 5*5 - 2
23 = 23]
So for this you will be doing proportions. Your equation will look like this: 
Firstly, cross multiply: 
Next, square root both sides of the equation, and your answer should be
