Each intercept should be equal to zero to solve x and y
Answer:
The length of the pother piece of the wood is 25 cm.
Step-by-step explanation:
Let the length of a piece of wood is x such that the ratio of two pieces is 2:5. Two pieces are 2x and 5 x
Length of the first piece is 10 cm. It means, 2x = 10 i.e. x = 5
We have considered that the length of other piece is 5x. It means 5×5 = 25 cm.
Hence, the length of the pother piece of the wood is 25 cm
Answer: 63/2π
Step-by-step explanation: C=πd
63=πd
D=63/π
r=1/2d
1/2×63/π=<u>63/2π</u>
Answer:
x=6
Step-by-step explanation:
2(x-4)+x=10
expand into 3x-8
add 8 to both sides 3x-8+8=10+8
simplify 3x=18
divide both sides by 3 3x/3=18/3
simplify x=6
