Answer:
B
Step-by-step explanation:
The number is between 10 and 49
The number is divisible by 3
Let the 10s digit = x
Let the units digit = y
1/3 * (10x + y) = x + y multiply both sides by 3
10x + y = 3(x +y) remove the brackets.
10x +y = 3x + 3y Subtract 3x from both sides
10x - 3x + y = 3y Combine\
7x + y = 3y Subtract y from both sides.
7x = 3y - y Combine
7x = 2y
x can't be very big. Even taking 1/3 will get out of range is you use 6.
Also x should be an even number. The units digit cannot have a fraction in it.
Try making x = 2
7*2 = 2*y
14 = 2y Divide by 2
14/2 = y
y = 7
So the number is possibly 27. Let's check it out.
- The number is between and includes 10 and 49. 27 is between these two endpoints.
- 27 is divisible by 3
- 1/3(27) = sum of digits
- 9 = (2 + 7)
All of the conditions are met. It's B
Answer:
3089/11220
Approximately = 0.2753
Step-by-step explanation:
Patel estimates that he needs 2 cups of Orange juice.
But let's know the amount he already has.
4/17 + 3/10 + 9/20 + 3/11 + 7/15
= 3/10 + 9/20 + 7/15 + 3/11 + 4/17
=( 18 + 27 + 28)/60 + (51+44)/187
= 73/60 + 95/187
=( 13651 + 5700)/11220
= 19351/11220
= 1(8131/11220)
So to complete it two he needs ( 11220-8131)/11220= 3089/11220
Approximately = 0.2753
