Is my answer correct

kondor19780726 [428]

Answer:

Yes, you are correct.

Step-by-step explanation:

$\text{Let the number of puzzle solved by Child B is} x\text{.}$

$\text{Then the average number of puzzle solved is}$

$\frac{5x+x+(x+4)}{3}=13$

$\frac{7x+4}{3}=13$

$7x+4=39$

$7x=35$

$x=5$

$\text{Therefore, the number of puzzles solved by child A is }5x=5\cdot5=25$

$\color{blue}\text{A little tips here: You can check it by substituting your answer to the original equation.}$

The conversion rates between kilograms and pounds are: 1 k g ≈ 2.2 l b s 1 l b ≈ 0.454 k g A. How many kilograms is a backpack t

denis-greek [22]

Answer:

$6\ lb = 2.724\ kg$

$11\ kg = 24.2\ lb$

Step-by-step explanation:

Given

$1\ kg = 2.2\ lb$

$1\ lb = 0.454\ kg$

Required

- Convert 6 lb to kg

- Convert 11kg to lb

To solve for (a), we make use of the second conversion unit:

$1\ lb = 0.454\ kg$

Multiply both sides by 6

$6 * 1\ lb = 0.454\ kg * 6$

$6\ lb = 2.724\ kg$

<em>Hence, a 6lb backpack weighs 2.724kg</em>

Solving (b): 11 kg to lb

Here, we make use of the first conversion unit

$1\ kg = 2.2\ lb$

Multiply both sides by 11

$11 * 1\ kg = 2.2\ lb * 11$

$11\ kg = 24.2\ lb$

<em>Hence, the cat weighs 24.2lb</em>
