Answer:
The estimated sum is ≈10
Step-by-step explanation:
This depends on how your professor wants you to estimate sums. Logically, though, a value of nearly 4 and a value of just over 6 add to about 10. The exact answer would be a bit over 10, at ≈10.14117
Answer:
We can eliminate the second and third options because marking something up doesn't result in a number less than the original. Since we are told to select 3 options and there are 3 answer choices left we select the first, fourth, and fifth statements.
Answer:
2nd number = 13
First number = 15
3rd number = 30
Step-by-step explanation:
Let
2nd number = 1/2x - 2
First number = 1/2x
3rd number = x
Total = 58
x + 1/2x + 1/2x - 2 = 58
x + x+x/2 = 58 + 2
x + 2/2x = 60
x + x = 60
2x = 60
x = 60/2
= 30
x = 30
2nd number = 1/2x - 2
= 1/2*30 - 2
= 15 - 2
= 13
First number = 1/2x
= 1/2*30
= 15
3rd number = x
= 30
