Answer:
-18
Step-by-step explanation:
The tall sticks around n+5 are absolute value signs. Basically, all you need to do is work out what the answer to the problem is inside the signs, then make whatever the answer is positive, then multiply by -9.
-7 + 5 = -2 (that turns into 2)
-9 x 2 = -18
Answer:
51
Step-by-step explanation:
The possible components to sum up to 101 can only be divided into 2 groups, 1 is larger than 50 and the other is less than or equals to 50
For example
50 + 51 = 101
52 + 49 = 101
60 + 41 = 101
...
99 + 2 = 101
100 + 1 = 101
Therefore, the worst case scenario is to pick all numbers from only 1 group, either all number less than or equal to 50, which there are 50 of them from 1 to 50, or greater than 50, which there are 50 of them from 51 to 100.
So k has to be at least 51 to guarantee that at least one pair of the selected integers will sum to 101
Answer: answer A
Step-by-step explanation:
Answer:
70
Step-by-step explanation:
to solve : start wit the inside brackets first
10 [25-{8-6 (16-13)}÷5 start 16-3
10[25-{8-6(3)}÷5 then multiply 6 and 3
10[25-{8-18}]÷5 then subtract 8-18
10[25-(-10)]÷5
10[25+10)÷5 add numbers inside brackets
10×35÷5=70 multiply and divide
