Answer:
i don't know I have the same problem
Let the number of goats be 'x'.
Therefore, the number of chicken will be 50-x
Total number of legs the goats will have= 4x (goats have 4 legs)
Total number of legs chickens will have= 2(50-x) (chickens have two legs).
4x + 2(50-x)=140
4x+100-2x=140
2x+100=140
2x=40
x=20.
There are 20 goats and 30 chickens.
Answer:
B
Step-by-step explanation:
3 x X = 3x 3 x 2 = 6 so 4x + 3x = 7x +6
The area for the figure is 146
Answer:
The area of the black portion = 219.752280681013 cm²
Step-by-step explanation:
<u><em>the canvas has the shape of a square </em></u>
<u><em>with sides of length 8×4 = 32 cm</em></u>
Then
<u>• The area of the canvas</u>
= 32²
= 1024 cm²
<u>•• The area of the four circles</u>
= 4×(π×8^2)
= 804.247719318987 cm²
<u>••• The area of the black portion</u>
= 1 024 - 804.247719318987
= 219.752280681013 cm²
