Answer - c </= 4 or c >/= -3
2c - 1 </ 7
2c - 1 + 1 </= 7 +1
2c </= 8
2c/2 </= 8/2
c </= 4
2c - 1 >/= - 7
2c - 1 + 1 >/= -7 + 1
2c >/= -6
2c/2 >/= -6/2
c >/= -3

Answer:
64
Step-by-step explanation:
115 - 51 = 64
Explanation:
This can be explained by thinking numbers on the number line as:
Lets take we have to multiply a positive number (say, 2) with a negative number say (-3)
<u>2×(-3)</u>
Suppose someone is standing at 0 on the number line and to go to cover -3 , the person moves 3 units in the left hand side. Since, we have to compute for 2×(-3), The person has to cover the same distance twice. At last, he will be standing at -6, which is a negative number.
A image is shown below to represent the same.
<u>Thus, a positive times a negative is a negative number.</u>
