Whatever you do to the numerator you must do to the denominator so 3 goes into 42 14 times so 3x14=42 2x14=28 so 2/3is equivalent to 28/42
Answer:
15 weeks
Step-by-step explanation:
For Barbie, keep subtracting 80 from 1,500 until you get to the lowest amount.
And for Ken, keep subtracting 20 from 600.
Once you are done, you will notice that both Barbie and Ken have $300 at 15 weeks. So your answer is 15.
Answer:
Ounces :)
Step-by-step explanation:
Given that
log (x+y)/5 =( 1/2) {log x+logy}
We know that
log a+ log b = log ab
⇛log (x+y)/5 =( 1/2) log(xy)
We know that log a^m = m log a
⇛log (x+y)/5 = log (xy)^1/2
⇛log (x+y)/5 = log√(xy)
⇛(x+y)/5 = √(xy)
On squaring both sides then
⇛{ (x+y)/5}^2 = {√(xy)}^2
⇛(x+y)^2/5^2 = xy
⇛(x^2+y^2+2xy)/25 = xy
⇛x^2+y^2+2xy = 25xy
⇛x^2+y^2 = 25xy-2xy
⇛x^2+y^2 = 23xy
⇛( x^2+y^2)/xy = 23
⇛(x^2/xy) +(y^2/xy) = 23
⇛{(x×x)/xy} +{(y×y)/xy} = 23
⇛(x/y)+(y/x) = 23
Therefore, (x/y)+(y/x) = 23
Hence, the value of (x/y)+(y/x) is 23.
