55/100 can be simplified to 11/20
Step-by-step explanation:
1)
Let x=larger number
y=smaller number
x+y=59
x-y=13
Now adding these two equations we get
2x=72
x=36
Now as x-y=13
y=x-13=36-13=23
y=23
Therefore the larger number is 36 and the smaller number is 23
(or else u could also write)
The numbers are 36 and 23
---------------------------------------------
2)
Let x=first number
y=Second number
x+y=15
2x-y=6
Now adding these two equations we get
3x=21
x=7
Now as x+y=15,
y=15-x=15-7=8
y=8
Therefore the first number is 7 and the second number is 8
-------------------------------------------
3)
Let x=Larger number
y=smaller number
x-y=3
x-3y=-11
Now on subtracting these two equations we get
2y=14
y=7
Now as x-y=3,
x=y+3=7+3=10
x=10
Therefore the larger number is 10 and the smaller number is 7
She would travel 1,234 miles. 2x14=110 80x55=1120+110= 1234 miles
Answer: 1) 2.059
2) 3.220
<u>Step-by-step explanation:</u>
1) log₆ 40
= log₆(5 x 8)
= log₆5 + log₆8
= 0.898 + 1.161
= 2.059
2) log₆ 320
= log₆ (40 x 8)
= log₆40 + log₆8
= 2.059 + 1.161
= 3.220
For that question the answer is 40nickels/standard coin
