Answer:
17x - 15y
Step-by-step explanation:
(10x - 7y) + (7x -8y)
17x - 15y
Answer:
The correct answer is the first solution set.
Step-by-step explanation:
If we substitute -20 into the equation we get
-20+17≤-3
-3≤-3
So,the inequality is right.
We can check the second one
14+17≤-3
31≤3 The inequality is false.
We can check the last one
-20+17≤-3
-3≤3 It works however there is a difference between the first one and the last one and that is the sign.For the first one there x≤-20 meaning the greatest number x can be is -20.For the last one x≥-20 which means -20 is the least value x can be.
If we substitude -21 into the equation we get
-21+17≤-3
-4≤-3
The inequality is false because -4 is not smaller than -3.
So,the right answer is the first solution set.
Answer:
the perimeter is 16
Step-by-step explanation:
The computation of the shape on this centimeter grid is shown below:
As we can see in the attached figure that the some portion is highlighted
So if we count that
like
So after counting it comes 16
Therefore the perimeter is 16
