Step-by-step explanation:
-3 (v + 4) = 2v - 37
-3v - 12 = 2v - 37
5v = 25
v = 5
C1/C2 = 2/3
2pi r1 / 2pi r2 = r1/r2 = 2/3
r1/39 = 2/3
r1 = 39*2/3 = 26
So, your answer is 26cm
16. You add 13 to 35 which makes 3y=48. Then to get y by itself you have to divide both sides by 3. 48/3=16.
Answer:
52 × 2 - 31 = 73
Step-by-step explanation:
Use PEMDAS
The way I remember is like this..
Please (Parentheses)
Excuse (Exponents)
My (Multiication)
Dear (Division)
Aunt (Addition)
Sally (Subtraction)
Multiply 52 × 2
which gives you 104.
Then subtract 31 from 101
and that will give you 73.
