A square has four even sides and the perimeter is equal to the sum of all of the sides.
$P=s+s+s+s=4s$
So we can evaluate the equation for P and then solve for s.
$78.4=4s \\ \frac{78.4}{4} =s \\ s=19.6in$

Claire walked her dog 2 1/5 miles. Carson walked her dog 1 3/4 times as far as Claire did. How many more miles did Carson walk h

Anon25 [30]

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Carson walked her dog 1 13/20 more miles than Claire did.

Sorry for the lazy explanations Imao

$\large\underline{\sf{Solution-}}$

$\textsf{Given expression;}\\$

$\rm{23 = \frac{7}{9}(6x - 36) + 9 } \\$

$\rm{\longmapsto} \: 23 = \frac{(42x - 256)}{9} + 9 \\$

$\rm{\longmapsto} \: 23 = \frac{(42x - 256 + 81)}{9} \\$

$\rm{\longmapsto} \: 23 = \frac{(42x - 175)}{9} \\$

$\rm{\longmapsto} \: \frac{23}{1} = \frac{(42x - 175)}{9} \\$

$\textsf{By doing cross multiplication, we get}\\$

$\rm{\longmapsto}23(9) = 1(42x - 175) \\$

$\rm{\longmapsto}207 =42x - 175\\$

$\rm{\longmapsto} \: 42x = - 175 - 207 \\$

$\rm{\longmapsto} \: 42x = - 379 \\$

$\rm \therefore \: x = - \frac{375}{42} \\$

$\textsf{Hence, the value of x will be -375/42 respectively.}\\$

A baby was born 3/4 of a month early. At birth its weight was 7/8 kilograms, which is 9/10 kilograms less than the average weigh

BlackZzzverrR [31]

Answer:

The average weight of a newborn otter is 1.775 kg.

Step-by-step explanation:

We are given the following in the question:

Weight of newborn otter =

$\dfrac{7}{8}\text{ kg}$

Let x lg be the average weight of a newborn otter.

Thus, we are given the relation:

$\dfrac{7}{8} = x - \dfrac{9}{10}\\\\x = \dfrac{7}{8} + \dfrac{9}{10}\\\\x = \dfrac{35+36}{40} = \dfrac{71}{40}\\\\x = 1.775\text{ kg}$

Thus, the average weight of a newborn otter is 1.775 kg.
