Answer:
6.5 m^2
Step-by-step explanation:
The area of a parallelogram is calculated by multiplying height to the base
If the area is 78 m^2 and base is 12 we can find the height by dividing the area by base
78 ÷ 12 = 6.5 m^2
Answer:
5.5
Step-by-step explanation:
1, 2, 5, 5, 6, 8, 9, 9
5+6=11
11 divided by 2= 5.5
The answer is 10/14
How: 7 is half of 14 so 14 would be the denominator which is the bottom number. So what would 5 be half of? (think of 5+5) It's 10! So 10 would be the numerator which is on the top making the fraction 10/14.
Hope this Helps!

here is a spreadsheet to help you understand the stair problem notice for 1 step 1 block, 2 step, 3 block, 3 step, 6 block and so on notice the blocks for the number of a step is that step plus all the other blocks needed to make all the one(s) below it. Notice it takes 105 blocks to make 14 steps.
So if you are familiar with the summation process you would add the number that go with that stair with all the stairs below it. example step 5 blocks would be 5 + 4 + 3 + 2 +1 or 15 blocks. I hope this gets you started. The second part I do not understand the problems because they are not equations. NO equal signs
glad if it helps
