Answer:
C. For every 4 giraffes in the zoo, there are 10 monkeys
Step-by-step explanation:
The ratio of the number of giraffes to the number of monkeys in a zoo = 2 : 5
giraffes : monkeys
4 : 10
4/2 : 10/2
2 : 5
So, For every 4 giraffes in the zoo, there are 10 monkeys
I'll just assign a value of x and solve it so that I'll be able to arrange them in order from greatest to least.
I am assuming that x = 2.
4x + 9 ⇒ 4(2) + 9 = 8 + 9 = 17
9^x + 1 ⇒ 9² + 1= 81 + 1 = 82
x² + 3 ⇒ 2² + 3 = 4 + 3 = 7
4x ⇒ 4(2) = 8
9^x ⇒ 9² = 81
x² ⇒ 2² = 4
based on my assumption, the order from greatest value to least value is:
1) 9^x + 1
2) 9^x
3) 4x + 9
4) 4x
5) x² + 3
6) x²
