Answer:
Step-by-step explanation:
In order to make d the subject of the formula, you need to isolate it.
- You started with d-7 = 4d + 3/e
- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...
d - 7 = 4d + 3/e This will leave you left with -3d - 7 = 3/e
-4d -4d
- Then move over the -7 by adding 7 to both sides...
-3d - 7 = 3/e This will leave you left with -3d = 3/e + 7
+7 +7
- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...
- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be
Answer:
0.99
Step-by-step explanation:
1.98 - 0.99 is 0.99.
Easy.
Just do it like you would any other problem.
The figure consists of a rectangle and a circle.
first lets find the sides of the triangle
sides of the triangle are 4+4=8 and 3+1=4
therefore area of the rectangle is 8*4=32
now area of semicircle =πr^2/2 = π2^2/2=2π=6.3
we have to add the area of rectangle with the area of semicircle
this is because it the given figure no part of area of circle and rectangle are in common.
therefore total area of given figure = 32+6.3=38.3
Assuming the possible digits are from 0-9, there are 10*9*8 possibilities which come out to 720
If you would like to know how many hours did Eric practice the piano this week, you can calculate this using the following steps:
the piano: 3/4 of 8 hours = 3/4 * 8 hours = 6 hours
The correct result would be 6 hours.
