$6.75 + $4.25 = $10.00
$15.95 - $10.00 = $5.95
The answer is $5.95
The left side was cut out but x will be on top and 5 in the lower square. The last one is the answer.
Answer:
B) Subtract 12-4 to calculate the range of this data set
Pretend these are coordinates that you can use to find the slope of the line.
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:

and the slope is 4. Now use one of the points and the slope of 4 to solve for b, the y-intercept:
40 = 4(10) + b so b = 0. The equation of the line then is y = 4x + 0 or just
y = 4x
63 5 tens=50
13 ones=10 and 3 leftover 50+13=63
