How should 48 eggs be divided so that the ratio is 4:3:5

1 answer:

5 0

Do 4+3+5 which = 12
then do 48 divided by 12 which is 4
Now 4 x 4 = 16
3 x 4 = 12
5 x 4 = 20
16 + 12 + 20 = 48 so its divided as 16:12:20

What values of x satisfy the equation x^2=6?

Otrada [13]

Answer

X = 8

Step-by-step explanation:

1x - 2 = 6

1x = 6 + 2

1x = 8 (divide both sides by 1 to get x)

1x/1 = 8/1

x = 8

Solve the following equation. Remember to check for extraneous solutions 7/(b+3) + 5/(b-3) = (10b-2)/(b²-9).

vlabodo [156]

Answer:

b= 2 is the solution for the given equation.

Step-by-step explanation:

Here, the given expression is:

$\frac{7}{(b+3)} + \frac{5}{(b-3)} = \frac{10b -2}{(b^{2} -9)}$

Simplifying Left side, we get

$\frac{7}{(b+3)} + \frac{5}{(b-3)}$

= $\frac{7(b-3) + 5(b+3)}{(b+3)(b-3)}$

Also, by ALGEBARIC IDENTITY: $x^{2} -y^{2} = (x+y)(x-y)$

So, $(b+3)(b-3) = b^{2} -9$

So, LHS becomes $\frac{7(b-3) + 5(b+3)}{b^{2} -9}$

Compare both Left side, Right side we get

$\frac{7(b-3) + 5(b+3)}{b^{2} -9}$ = $\frac{10b -2}{(b^{2} -9)}$

or, 7(b-3) + 5(b+3) = 10b -2

⇒ 7b - 21 + 5b + 15 = 10b -2

or, 12b - 10b = 6-2

or, 2b = 4 ⇒ b = 4/2 = 2

⇒ b= 2 is the solution for the given equation.
