A restraurant owner estimates that his restaurant will sever 430 customers the first week it is open the actual number of customers the first week is 400 find the percent error

7.5% error

Step-by-step explanation:

Percent Error = ( | measured - real | / real ) x 100%

|430 - 400| / 400 = |-30| / 400

( 30 / 400 ) x 100%

= 7.5%

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
