800 + 60 + 3 + 0.1 + 0.04 + 0.001
Answer:x=2, y=3
Step-by-step explanation:
solving this equation simultaneously
-9x - 2y=-12.............(1)
2x + 5y=-11.. ...........(2)
Using elimination method
Multiply equation 2 by 2 and equation 1 by 5
-45x -10y= -60...........(3)
4x + 10y=-22...............(4)
Subtracting equation 2 from 1
-41x + 0=-82
41x=82
x=82/41
X=2
To find y put x in equation 1
-9x - 2y= -12
-9(2)-2y=-12
-18-2y=-12
-2y=-12+18
-2y=6
Y= 6/2
Y=3
X=2, Y=3
Answer:
20
Step-by-step explanation:
24.80-6.80=$18 that's what Britta spent on equal number of carrots and apples because $6.80 was spent on extra carrots only.
18/ .90=20 that means she got 20 apples and 20 carrots before she added $6.80 to buy some extra carrots
Thus, the number of apples Britta bought = 20

Answer:
Roll two dices
Step-by-step explanation:
Every dice rolled has two chances of six of winning by showing a 1 or 2, which is the same as one chance of three.
On the opposite, you have four chances of six of loosing by getting a 3,4,5 or 6, which is the same as two chances of three.
Since the chances of loosing are bigger than the ones of winning, every roll makes it more probable of getting a 3,4,5 or 6, so you need to roll as few dices as possible, in this case two is the minimum allowed.
