Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre
natta225 [31]

Answer:

10 rabbits

Step-by-step explanation:

Let us represent

Number of rabbits = x

Number of squirrels = y

Number of deer = z

Katniss caught three times as many squirrels as deer.

y = 3z

She also caught five less rabbits than squirrels.

y = x - 5

The total number of animals she caught is ten more than four times the number of deer caught.

x + y + z = 4 × z + 10

x + y + z = 4z + 10

How many rabbits did Katniss catch?

Number of rabbits = x

We make x subject of the formula

x + y + z = 4z + 10

x = 4z + 10 - y - z

y = 3z

x = 4z + 10 - 3z - z

x = 4z - z - 3z + 10

x = 4z - 4z + 10

x = 0 + 10

x = 10

Therefore, the number of rabbits Katniss caught is 10 rabbits

Answer:

102.62

Step-by-step explanation:

I converted everything to inches and then solved for x by putting 58 in. over 66 in. (the girls shadow in in.) and the X in. over 1500 in. I cross multiplied (58 x 1500 and 68 x X) and then divided 68 by the result of 58 x 1500.
