Solve. {y=x−7 {5x+2y=7 use the substitution method. a. (−1, −8) b. (0, −7) c. (7, 0) d. (3, −4)

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

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
