Answer:
x ≤ 6
Step-by-step explanation:
Distribute the 5 onto (x-2), then combine like terms.
5x -10 -3x ≤ 2
2x - 10 ≤ 2
Add 10 to both sides to get rid of the 10 on the left.
2x - 10 + 10 ≤ 2 + 10
2x ≤ 12
Divide 12 by 2.
x ≤ 6
x ≤ 6 will be your answer/solution.
Answer:1
Step-by-step explanation:
Number selected, =10
Double it=20
Minus 2= 20-2=18
Triple the Total =18×3=54
Add a dozen=54+12=66
Divide by 6=66÷6=11
Subtract the number you stated with =11-10=1
Answer =1
