UNO [17]

Answer:

14.6

Step-by-step explanation:

It is given that,

The average weight of the top 5 fish caught at a fishing tournament was 12.3 pounds. From the attached figure, the weight of 5 fish are given. We need to find the weight of Wayne S. fish.

Average = sum of terms/no of terms

Let the weight of Wayne S. is x. So,

Here the sum of terms is x+12.8+12.6+11.8+9.7 and the number of terms is 5.

$12.3=\dfrac{x+12.8+12.6+11.8+9.7}{5}\\\\61.5=x+12.8+12.6+11.8+9.7\\\\61.5=x+46.9\\\\x=14.6$

So, the weight of the heaviest fish is 14.6.

Which of the following is the solution to 11/(x+2) = 4/(x-1)?

lara [203]

$Solution, \frac{11}{\left(x+2\right)}=\frac{4}{\left(x-1\right)}\quad :\quad x=\frac{19}{7}\quad \left(\mathrm{Decimal:\quad }x=2.71429\dots \right)$

$Steps:$

$\frac{11}{\left(x+2\right)}=\frac{4}{\left(x-1\right)}$

$\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c, 11\left(x-1\right)=\left(x+2\right)\cdot \:4$
