A number d minus 2 is less than -1 ?
2 answers:
d - 2 < -1 is how this inequality would be displayed.
However, we can solve for the value of d by treating this like a standard algebraic equation.
d - 2 < -1
<em><u>Add 2 to both sides.</u></em>
d < 1
The value of d is less than 1.
Let me know if you have any other questions.
Answer:
Given phrase,
a number d minus 2 is less than -1
∵ '-' is the sign of minus,
⇒ d minus 2 = d - 2
Also, '<' is the sign of less than,
⇒ d minus 2 is less than -1 = d - 2 < - 1
Hence, the required inequality would be,

Now, by further solving,
Add 2 on the both sides of inequality ( additive property of inequality )

⇒ d ∈ ( -∞, 1 )

She drove 2 hours at 70 miles per hour, so she drove 70 * 2 = 140 miles total.
The jet traveled 400 miles per hour for 2 hours for a total of 400 * 2 = 800 miles.
Total miles = 140 + 800 = 940 miles.

Answer:
2/3 =x
Step-by-step explanation:
f(x) = 3x - 2
Let f(x) =0
0 = 3x-2
Add 2 to each side
2 = 3x-2+2
2 =3x
Divide by 3
2/3 =3x/3
2/3 =x
