There are altogether $\fbox{\begin{minispace}\\188 \text{legs}\\\end{minispace}}$ .

Further explanation:

Given:

The number of Unicorns is four: Stardust, Umo, WIndthorn and Highflyer.

The number of Spiders in the tree is five.

The number of cockroaches is five.

The number of bees is seven.

The number of deer is three.

The number of cows is 4.

The number of antlers is 2.

To calculate:

The total number of legs of all the creatures.

Calculations:

It can be seen that the number of legs of a unicorn is 4.

Since, there are four unicorns, it means that the number of legs of unicorns $n _{1}$ can be calculated as,

$n_{1}= 4 \times 4 \\ \fbox{\begin{minispace} \\ n_{1} = 16 \end{minispace}}$

Also, the number of legs of a spider is 8.

Therefore, the number of legs $n_{2}$ of eight spiders can be calculated as,

$n_{2}= 8 \times 8 \\ \fbox{\begin{minispace} \\ n_{2} = 64 \end{minispace}}$

Now, the number of legs of a cockroach is 6, it means that the number of legs $n_{3}$ of five cockroaches can be calculated as,

$n_{3}= 6 \times 5\\ \fbox{\begin{minispace} \\ n_{3} = 30 \end{minispace}}$

Also, the number of legs of a bee is 6, therefore the number of legs $n_{4}$ of seven bees can be calculated as,

$n_{4}= 6 \times 7\\ \fbox{\begin{minispace} \\ n_{4} = 42 \end{minispace}}$

The number of legs of a deer is 4 which lead to the number of legs $n_{5}$ of three deers as,

$n_{5}= 4 \times 3\\ \fbox{\begin{minispace}\\ n_{5} = 12 \end{minispace}}$

The number of legs of a cow is 4 that means the number of legs $n_{6}$ of four cows can be calculated as,

$n_{6}= 4 \times 4\\ \fbox{\begin{minispace} \\ n_{6} = 16 \end{minispace}}$

Also, since it can be seen that a pair of antlers is seen, so it means that the animal seems to be two deers.

Now, a deer has 4 legs, it means that the number of legs $n_{7}$ of two deer is,

$n_{7}= 4 \times 2\\ \fbox{\begin{minispace} \\ n_{7} = 8 \end{minispace}}$

Therefore, the total number of legs can be obtained by adding the values of $n_{1}, n_{2}, n_{3} , n_{4} , n_{5}, n_{6} \text{ and } n_{7}$ .

$n=n_{1}+n_{2}+n_{3}+n_{4}+n_{5}+n_{6}+n_{7}\\ n=16+64+30+42+12+16+8 \\ \fbox{\begin{minispace} \\ n = 188 \end{minispace}}$

Therefore, the total number of legs altogether are 188.

Answer from: Quest

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
