Total marbles = 40 & 1/4 (or 0.25) are, then RED = 40x 0.25 = 10
If RED = 10 then BLUE = 30
P(picking one blue) = 30/40 = 3/4 =0.75
Answer:
Step-by-step explanation:
Let the larger number = x
Smaller number = y
6x + 7y = 114 ------------(I)
10x - 9y = 66 ------------(II)
Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x
(1)*9 54x + 63y = 1026
(II)*7 <u>70x - 63y = 462</u> {Now add}
124x = 1488 {Divide both sides by 124}
x = 1488/124
x = 12
Plugin x = 12 in any of the equation. Here, We are substituting in equation (I)
6*12 + 7y = 114
72 + 7y =114
7y = 114 - 72
7y = 42
y = 42/7
y = 6
The numbers are 12 , 6
Answer:
112 rooms
Step-by-step explanation:
Simply if 10% of 140 is 14 20% of 140 is 28. So then 28 substract 140 is 112
