aalyn [17]

Answer:the number of 2 legged animals in the zoo is 9

the number of 4 legged animals in the zoo is 7

Step-by-step explanation:

Let x represent the number of 2 legged animals in the zoo.

Let y represent the number of 4 legged animals in the zoo.

There a 46 legs in the exhibit in the zoo. This means that

2x + 4y = 46 - - - - - - - - - -1

There are 2 more 2 legged animals than 4 legged animals. This means that

x - 2 = y

Substituting y = x - 2 into equation 1, it becomes

2x + 4(x - 2) = 46

2x + 4x - 8 = 46

6x = 54

x = 54/6 = 9

Substituting x = 9 into x - 2 = y, it becomes

y = 9 - 2 = 7

Tyler cut 40 1/8 inch board into 3 pieces of equal length. He then cut 3 3/4 iches off of each piece to make smaller boards. Wha

Deffense [45]

Answer:

$9\frac{5}{8}\ inches$

Step-by-step explanation:

The original board is 40 1/8 inch and it is cut in 3 pieces of equal length:

New boards = $40\frac{1}{8} : 3 = \frac{321}{8} * \frac{1}{3} = \frac{107}{8}$

And now he cuts again 3 3/4 inches off of each one of the new boards (substracts)

$\frac{107}{8} - 3\frac{3}{4} =\frac{107}{8} -\frac{15}{4} =\frac{107-30}{8} =\frac{77}{8} =9\frac{5}{8} \ inches$

Advocard [28]

Trevion received the better one because he got it for 30.60

Step-by-step explanation:

Original price of cap bought by James = 38.99

Sale = 20% off

Amount of discount = $\frac{20}{100}*38.99=\frac{779.8}{100}$

Amount of discount = 7.80

Purchase price = Original price - Amount of discount

Purchase price = 38.99 - 7.80 = 31.19

Original price of cap bought by trevion

Sale = 10% off

Amount of discount = $\frac{10}{100}*34=\frac{340}{100}$

Amount of discount = 3.40

Purchase price = 34 - 3.40 = 30.60

Trevion received the better one because he got it for 30.60
