Step-by-step explanation:
The missing step in solving the inequality is x > -9
<h3>Solving inequalities </h3>
From the question, we are to determine the missing step in solving the given inequality
1. The distributive property: 4x – 12 + 4 < 10 + 6x
2. Combine like terms: 4x – 8 < 10 + 6x
3. The addition property of inequality: 4x < 18 + 6x
4. The subtraction property of inequality: –2x < 18
5. The division property of inequality: ________
Applying the division property of inequality
-2x/-2 < 18/-2
x > -9
Hence, the missing step in solving the inequality is x > -9

Answer: 40/7, if you need, the mixed fraction is 5 5/7
Step-by-step explanation:
First of all, convert all the mixed fraction into improper fraction.
2 2/3=8/3
2 1/7=15/7
Then do the multiplication.
8/3 × 15/7=120/21=40/7 (You can directly simplify it to 40/7 since you can use 15 divided by 3 to get 5 left in the numerator)
Hope this helps!! :)

Answer:
80 km/h
Step-by-step explanation:
Let p represent the planned speed in km/h. Using the relation ...
... distance = speed × time
we can take advantage of the fact that the planned trip distance did not change.
... p × 2.5 = (p+20) × (2.5 -0.5)
... 2.5p = 2p +40 . . . . simpify
... 0.5p = 40 . . . . . . . . subtract 2p
... p = 80 . . . . . . . . . . . divide by 0.5
The planned speed was 80 km/h.
It's 6x-18
