Answer:
60 males in the aquarium
Step-by-step explanation:
It is a ratio problem. The ratio of female goldfish to male goldrish is 6:10. If you divide 216 (females) by 6 (females), you get 36. If you multiply 10 times 6, you get 60. So, the ratio turns into 216: 60. So, there are 60 males in the aquarium.
Its a dilation of 2, I believe ........
I’m sure that the area is 80. If you do 10 times 5, that will be 50.Then if you do 6 times 5, for the upper remaining part of the figure it would be 30. So 30 plus 50 is 50. Hope this helps!
Answer:
y = 3
x = 2
Step-by-step explanation:
-5x + 4y = 2
9x - 4y = 6
Sum both eq.
-5x + 9x = 4x
+4y - 4y = 0
2 + 6 = 8
then:
4x + 0 = 8
4x = 8
x = 8/4
x = 2
from the first eq.
-5x + 4y = 2
-5*2 + 4y = 2
-10 + 4y = 2
4y = 2 + 10
4y = 12
y = 12/4
y = 3
Check:
from the second eq.
9x - 4y = 6
9*2 - 4*3 = 6
18 - 12 = 6
