Final answer:
To represent the equation 1.48+x=1.57 as an inequality, the inequality would be 1.48 + x ≤ 1.57.
Step-by-step explanation:
To represent the equation 1.48+x=1.57 as an inequality, we can use the less than or equal to symbol (≤) instead of the equal sign. Since the right side of the equation is already 1.57, we can simply write x is less than or equal to 1.57. The inequality would be:
1.48 + x ≤ 1.57
