There are five more chickens than rabbits in a backyard. The total number of legs are 130. How many chickens and rabbits?

1 answer:

3 0

A) c = r +5B) 2*c + 4 * r = 130
Substituting A) into B)B) 2 * (r + 5) + 4 * r = 130B) 2 * r + 10 + 4 * r = 130B) 6r = 12020 rabbits and therefore 25 chickens
Double-Check
2 * 25 + 4 * 20 = 130 total legs

The answer is 3. Divide 5375 by 4 to get 1343.75. Remainder for each friend is .75, so multiply .75 by 4. 3 cards left over.

Answer:

A) 1 : 4

B) 1 : 2

C) Base of M = 10 units

Step-by-step explanation:

The ratio of the area of triangle M to triangle N

$\frac {40}{160}= \frac{1}{4} = 1 : 4$

The ratio of the side lengths of triangle M to triangle N

$\sqrt{ \frac {40}{160}} = \sqrt{\frac{1}{4}} \\\\={\frac{1}{2}} \\\\=1 : 2$

C) Let the base of triangle M be b units.

$\sqrt{ \frac {40}{160}} = \frac{b}{20}\\\\\frac{1}{2}= \frac{b}{20}\\\\2b = 20\\\\b = \frac{20}{2} \\\\b = 10$
