The answer to 4-6 is negative 2
Children=x
Adults=y
* x + y =275 => x = 275 - y
* 3.00x + 6.40y = 1284 <=> 3.00(275 - y) + 6.40y = 1284 <=> ... <=> y = 135 => x = 275 - 135 = 140
Children: 140
Adults: 135
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
The answer to your question is : C. 30
You subtract 72 and 42
72-42=30
