Step-by-step explanation:
Let x represent the total number of red and blue beads
Angie has some red and blue beads. 40% of her beads were red. This means that the total number of red beads is
40/100 × x = 0.4x
The number of blue beads would be
x - 0.4x = 0.6x
When she lost 50 blue beads, the number of blue beads was reduced by 1/3 its original number of beads. This means that
0.6x - 50 = 0.6x - 0.6x/3
0.6x - 50 = 0.6x - 0.2x = 0.4x
0.6x - 0.4x = 50
0.2x = 50
x = 50/0.2 = 250
The number of blue beads that Angie had initially is
0.6 × 250 = 150
The number of blue beads that Angie has left is
150 - 50 = 100 beads
The number of beads that Angie has in the end is
250 - 50 = 200 beads
Answer:
(0,1)
Step-by-step explanation:
Simplify the equation to y = 1
A horizontal line always crosses the y axis.
Prim numbers between 30 and 60 are
31, 37, 41, 43, 47, 53, and 59
Using rounding I would change 198 to 200 and 727 to 730.
200 + 730 = 930. Some would change the 727 to 700 but I see no need to do that. My answer will be closer using 200+730.
You can also get the exact answer like this - when you raise 198 to 200, you raised it by 2 so to compensate, take 2 away from the other number and 727 becomes 725
I can do 200 + 725 = 925 in my head and that happens to be the exact answer.
