the average marks of rashid in first four papers is 88 .how much marks should he get in fith paper so that the average of his five papers becomes 90

98

Step-by-step explanation:

Average of current papers is:

 x 100 = 88

Therefore solve: x 100 = 90

x 100 = 90

352 + x = 450

x = 98

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
