Answer:
y+2, y+4
Step-by-step explanation:
Consecutive odd integers differ by 2.
The next two are ...
y+2
y+4

<em>Additional comment</em>
You may find it simplifies the math in consecutive integer problems if you let the variable represent the middle one. If y is the middle one, the three odd integers are represented by y-2, y, y+2.
a +b = 7
a-b = 3
Rewrite the second equation as a = 3+b
Replace a in the first equation with that:
3+b + b = 7
Simplify:
3 +2b = 7
Subtract 3 from both sides:
2b = 4
Divide both sides by 2:
b = 4/2 = 2
Now replace b in the first equation with 2 to solve for a:
a + 2 =7
a = 7-2 = 5
so you now have a and b.
Now solve the given equation:
2^a * 2^b
2^5 * 2^2
32*4
128
The answer is 128.
Answer:
168÷4
=42
Distance covered by train in 4 hours=168kms
Distance covered by train in 1 hour =168kms÷4hrs
=42
Thus distance covered by train in 1 hour is 42kms.
