Answer:
A) 92
Step-by-step explanation:
A full revolution is shown which means it should add up to 360.
To find b, subtract 227 and 41 from 360:
360 = 227 + 41 + b
b = 92
4/5 1/2 0.2 0.5 and apparently theres a character limit
Step-by-step explanation:
3(x - 4y) - 2(y + 7x)
= 3x - 12y - 2y - 14x
= 3x -14x -12y -2y
= -11x -14y
First Step: What two multiples have perfects squares that equal 48 and 12? P.S They also need to have a common multiple so you can combine like terms in the end.
16*3=48
4*3=12
Second Step: Now use those multiples to split up your square roots so you will have perfect squares.
2√48 + 2√12=
2√16 ×√3 + 2√4×√3= Now Simplify!
2×4×√3 + 2×2×√3= Multiply!
8√3 + 4√3
Third Step: Now that they look alike you can just add them.
Answer: 12√3
Answer:
5b = 20
Step-by-step explanation:
Since Abdul bought b books and Debra bought 5 times as many books as Abdul, then 5b represents the number of books Debra bought. Since we know that Debra bought 20 books, we can write an equation to represent that: 5b = 20.
(Abdul bought 4 books in that case)
