Answer:
the first one
Step-by-step explanation:
75 is constant plus 13.5 every time and you want it to be equal or more than 130
15/4
how many times does 4 go into 15 without going over.....that would be 3 times....so 3 is ur whole number. 3 * 4 = 12......15 - 12 = 3...and 3 is ur numerator....the denominator stays the same
so ur answer is : 3 3/4
Answer:
15
Step-by-step explanation:
3a+9=54
-9 -9
3a=45
:3 :3
a=15
<span>the line over the 28 means the 28 repeats forever.
1.282828.... and so on
let x be the rational number 1.28...
we can use this trick:
100*1.282828....= 128.282828...
(the decimal 28 part repeats)
100x = 128.28...
next:
100x - x = 128.282828... - 1.282828...
the .282828... part will be subtracted away
99x = 127
divide both sides by 99 to get
x= 127/99</span>
