Answer:
Step-by-step explanation:
The trick here (and it is tricky!) is to find the area of the parallelogram as a whole based on the information you're given, and then use that area to solve for h. If we look at the parallelogram sideways and use 5.5 as the height, the base is 9.9. The area for a parallelogram is A = bh, so A = 9.9(5.5) so
A = 54.45 in squared. Now we will use that area value along with the height of h and the base of 11. Remember, just because we are using different numbers this time, the area of the parallelogram doesn't change. Therefore,
54.45 = 11(h) and
h = 4.95 in.
Answer:
3
Step-by-step explanation:
2 + 5z > 17
5z > 17-2
5z > 15
5z/5 > 15/5
z > 3
Answer:13/50
Step-by-step explanation:
A. m = 0 || This is incorrect, because m being equal to 0 is a solution in and of itself.
B. m = m || This is incorrect, because m being equal to itself means that there are an infinite number of solutions.
C. 2m + 1 = m - 2 | m = -3 || This is incorrect, because m can be solved for and has a solution.
D. m + 4 = m - 4 | 4 = -4 || This is correct because 4 is not equal to -4, and thus there is no solution.
Hope this helps!! :)
