To solve for x, you need to isolate/get the variable "x" by itself in the equation:
x - 60 = 180 Add 60 on both sides to get "x" by itself
x - 60 + 60 = 180 + 60
x = 240
PROOF
x - 60 = 180 Substitute/plug in 240 into "x" since x = 240
240 - 60 = 180
180 = 180
Answer:
18312.5mm³
Step-by-step explanation:
Given parameters:
Height of cylinder = 18mm
radius = 18mm
Unknown:
Volume of the cylinder = ?
Solution:
The volume of cylinder is given as;
Volume = π r ² h
Insert the given parameters and solve;
Volume = 3.14 x 18² x 18
Volume = 18312.5mm³
Answer:
25
Step-by-step explanation:
4.5×5.5=24.75
so 24.75 is the area of the room but you have to buy whole tiles so you would need to but 25 tiles
Answer:
Step-by-step explanation:
cos theta is 2/3 because cos means reciprocal of sec
Answer: n=3
Step-by-step explanation:
Understand that you need to set up a proportion before you can try to solve the question through guessing. In this case, YZ would be proportional to XY as EF is proportional to DE. You would write this as: EF/DE=YZ/XY.
Now you want to write an equation. In order to do this remember to multiply by your proportion. Here’s my equation:
5/4(4n+4)=7n-1. Now distribute:
5n+5=7n-1. Now simplify:
6=2n. Now simplify again:
n=3
Hope this helps you with your big ideas math hw!
