Answer:
B. 11/18
Step-by-step explanation:
Solve using algebra.
x = 0.611111...
10x = 6.111111...
10x - x = 6.111111.. - 0.61111111..
9x = 5.5
x = 5.5/9
x = 11/18
You can set up a simple algebraic equivalent to find a number equivalent to 200 after being multiplied by 3 and added 11 to.
3x+11=200
3x=189
x=63
Had to edit! Realized what I had done wrong
b is correct! good job :)
55 / 100 = 0.55 which is 1%
0.55 x 40 = 22 which is 40%
55 - 22 = 33
The answer is $33
Answer:
b=7
Step-by-step explanation:
5a(2b – 3a) = 40
Let a=4
5*4(2b-3*4) = 40
20(2b-12) = 40
Divide each side by 20
20/20 (2b-12) = 40/20
2b-12 =2
Add 12 to each side
2b-12+12 = 2+12
2b = 14
Divide by 2
2b/2 = 14/2
b = 7
