there are 10 numbers you want either a 4 or 7 ( 2 numbers)
so probability is 2/10 which reduces to 1/5
answer.
Answer:
x=2 and y=0 is the required result.
Step-by-step explanation:
We have been given system of equations:
5x+2y=105x+2y=10 (1)
And 3x+2y=63x+2y=6 (2)
We will use elimination method:
Multiply 1st equation by 3 and 2nd equation by 5 we get:
15x+6y=3015x+6y=30 (3)
15x+10y=3015x+10y=30 (4)
Now subtract (4) from (3) we get:
-4y=0−4y=0
y=0y=0
Now, put y=0 in (1) equation:
5x+2(0)=105x+2(0)=10
5x=105x=10
x=2x=2
Hence, x=2 and y=0
60 onces is 15lbs so then i beleve you have 11lbs too much
From the given statement, we know the following...
0.35x = $247 where x = the orginial number
So if we solve for x by dividing by 0.35
x = $247/0.35 = $705.71
12.5% of the sample. hope it helped :)
