Yes, 5:10 and 2:4 are equivalent.
5:10 (simplified) = 1:2
2:4 (simplified) = 1:2
Hope this helps; have a great day!
Answer:
50°, 130°
Step-by-step explanation:
All measures are in degrees. Let x represent "one angle". Then the other is (180-x) and we can write the relation ...
3x = 20 +(180 -x)
4x = 200 . . . . . . . add x, collect terms
x = 50 . . . . . . . . . . one angle
180 -50 = 130 . . . .the other angle
The measures of each angle are 50° and 130°.
For number 1) You need to get m alone, so you must add 4.4 to 2.6.
For number 2) Same thing as #1
For number 3) You must get c alone, you need to divide 10 by 2.5
For number 4) Same as #3
For number 5) You need to get t alone, so you must multiply both sides by 2.5
For number 6) Same as #5
