9 can't go into 6 but 9 can go into 62 so the number of digits will be 2 in the tens place. If you're looking for the answer, it is 69.6666666667 but this will have a remainder.
69R2 but if that's wrong try it in long division

16.81 rounded to the nearest tenth would be 16.8 because 1 is less than 5 so the 8 would stay the same
16.81 rounded to the neared whole number would be 17 because 8 is more than 5 so 6 is rounded up
Hope this helped! :))

The tenths place is the place right after the decimal point. When rounding, you look at the next place over (which would be the hundredths place in this case) and look at the number closely. If it is 5 or more than 5, the hundredths place disappears and becomes 16.8. When rounding to a whole number, you do practically the same thing but you look at the ones place (the place right before the decimal point) and look at the next place over (tenths place). Again, is it 5 or more? Yes, so you round up to 17 and get rid of the tenths place and everything after.

Jennifer has two pennies. She flips both pennies 105 times each. How many times can she expect both pennies to come up heads simultaneously?
Assuming I have correctly interpreted your question,
The probability both coins come up heads is
Thus the expected number of simultaneous heads is 105/4 or 26.25

The solution is the point of intersection between the two equations.
Assuming you have a graphing calculator or a program to lets you graph equations (I use desmos) you simply put in the equetions and note down the coordinates of the point of intersection.
In the graph the first equation is in blue and the second in red.
The point of intersection = the solution = (-6 , -1)
If you dont have access to a graphing calculator you could draw the graphs by hand;
1) Draw a table of values for each equation; you do this by setting three or four values for x and calculating its image in y (you can use any values of x)
y = 0.5 x + 2 (Im writing 0.5 instead of 1/2 because I find its easier in this format)
x | y
-1 | 1.5 * y = 0.5 (-1) + 2 = 1.5
0 | 2 * y = 0.5 (0) + 2 = 2
1 | 2.5 * y = 0.5 (1) + 2 = 2.5
2 | 3 * y = 0.5 (2) + 2 = 3
y = x + 5
x | y
-1 | 4 * y = (-1) + 5 = 4
0 | 5 * y = (0) + 5 = 5
1 | 6 * y = (1) + 5 = 6
2 | 7 * y = (2) + 5 = 7
2) Plot these point on the graph
I suggest to use diffrent colored points or diffrent kinds of point markers (an x or a dot) to avoid confusion about which point belongs to which graph
3) Using a ruler draw a line connection all the dots of one graph and do the same for the other

y = mx + b - it's the equation of a straight line. We need only two points to the plotting the graph of that function.
Select any two x values and calculate y values:
Look at the picture.
The solution of the system of equations is the intersection point of the line.
Answer: (-6, -1) → x = -6 and y = -1
