The sum of two times a number and -2 is at least 8<br><br> how can I solve it plz help
Bogdan [553]
To solve, your equation would be 2x - 2 >/= 8. You add 2 to both sides, getting 2x >/= 10. Then divide by two on both sides, your answer would be x >/= 5. (x is greater than or equal to 5).

16- let x represent the number:


x+ (x+1)+(x+2)=100

collect like terms

3x+3=100

3x=97

x=~32 but we need an odd number so round to 31, since 33 would be too great

31+33+35=99

therefore, the three numbers are 31, 33, 35
