Write an equation. To do this, make one integer equal to x, and the other equal to x+1. Set these equal to 149. Your equation should read x+(x+1)=149. Solve. To do this, add the two x's together. Your equation is now 2x+1=149. Get your x's alone. First, subtract 1 from both sides. Now the equation is 148=2x. Divide both sides by 2 to get x alone. You now have x=74. Plug this value back into the original equation to find your value for the other integer, and you have the two integers as 74 and 75. Hope this helps!

a= l*w
a=1.5 * 0.75
a= 1.125
Answer: D
Step-by-step explanation:
Think of it logically: A and C are not below sea level so you can cross them out. And B doesn't work because if you decrease -10 by 10 you get -20. So, D is correct.

Is AB and CD parallel?
First, we need to calculate the slope (m) of AB and CD
For AB:
So:
For CD:
So:
For Lines to be parallel, the slope must be equal:
i.e. 
This condition is not true because:
For Lines to be perpendicular, the slope must be:
This implies:
<em>Hence, the lines are perpendicular</em>
