“the product of a number and 7”

We need to write two expressions for the given statement

Let the unknown number be 'n'

product means we multiply . So the product of a number and 7 can be written as  n  times 7  

product of a number n  and 7 is also 7n

So options B  and C  are correct

10

7+3=10

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
