Step-by-step explanation:
dilatation with scale factor (k) = 2
Answer:
18 pots.
Step-by-step explanation:
10/2 to get one of the longs. 5(2) to get the other one. 10.
8/4 to get one of the wides. 2(2) to get the other one. 4.
There are 4 corners so there are 4 extra pots. 4.
Add the numbers: 4+4+10. 18
The property where you multiply ig
Answer:
x = 3, y = - 2
Step-by-step explanation:
By substitution method,
4x + y = 10 -------> equation 1.
7x + 2y = 17 -------> equation 2.
From equation 1,
y = 10 - 4x ------> equation 3.
Substitute equation 3 in 2,
7x + 2 ( 10 - 4x ) = 17
7x + 20 - 8x = 17
7x - 8x = 17 - 20
- x = - 3
x = 3
Substitute x = 3 in equation 1,
4 ( 3 ) + y = 10
12 + y = 10
y = 10 - 12
y = - 2
Hence,
x = 3
y = - 2
