Answer:
youngest=115
middle=150
elder=230
Step-by-step explanation:
let the youngest be x
the middle will be x+35
the oldest will be 2x
x+x+35+2x=495
4x+35=495
4x=495-35
4x=460
x=115
since the youngest is x,the money he will receive is $115.
the middle will be x+35 which is equal to 115+35=$150.
lastly the oldest will be 2x which is equal to 2×115=$230.
Answer:
The expected ratio: 8/60 = x/2400
=> The number of flawed wrenches in a batch of 2400:
x = 2400*8/60 = 320
1/3+5/12=4/12+5/12=9/12=3/4 of guests choose meat

so
23 guests is 1/4 of all guests
23*4=92 all guests

We have to get enough sleep. All of us know how cranky we can get if we do not have enough sleep. And what's more " avoid stress, worry and tension, think positive!
