Answer:

63/5 or 12 (3/5)

Step-by-step explanation:

It is 8 whole (1 ÷ 5) plus 4 whole (2 ÷ 5)

So,we can write it as 8 (1/5) + 4 (2/5)

Then we will take those mixed fractions to improper fractions by using the rule of multiplication.

8 will be multiplied by 5 and then the value will be added to 1. Same rule will be applied for the second fraction.

(41÷5) + (22÷5)

Now we will take L.C.M. (Least common multiple) for both denominators 5 and 5. The L.C.M of 5 and 5 = 5

(41 + 22)/5

= 63/5

It is the answer. Also we can make this improper fraction into mixed fraction by dividing the whole number by 5.

12 (3/5)

Find y when x=15 if y=6 when x=30

Verdich [7]

Y = 12 because you multiply x by two to get x2, which is 30, and multiply y by two to get 12 - this is wrong, the answer is three, i did the math backwards

Solve the formula for the indicated variable. k=g-d/c for g

Murrr4er [49]

Just like any other variable, we complete the same process

$k = g - \frac{d}{c} \\ k + \frac{d}{c} = g \\ \frac{kc + d}{c} = g \\$
Now we can test it, let's say k=4, d=6, and c=2, let's find the value of g
$4 = g - \frac{6}{2} \\ 4 + 3 = g \\ 7= g$

OR

$\frac{kc + d}{c} = g \\ \\ \frac{(4 \times 2) + (6)}{(2)} = g \\ \frac{14}{2} = g \\ g = 7$

Whats the answer and how do you work it out?<br>5/12-1/4

Sergio [31]

Answer:

$\frac{5}{12} - \frac{1}{4} \frac{ \times }{ \times } \frac{3}{ 3 } \\ \frac{5}{12} - \frac{3}{12} \\ = \frac{2}{12} = \frac{1}{6}$
