Answer:
(x, y) = (8, 6)
Step-by-step explanation:
given the 2 equations
2x - y = 10 → (1)
2x - 2y = 4 → (2)
rearrange equation (1) expressing y in terms of x
y = 2x - 10 → (3)
Substitute y = 2x - 10 in equation (2)
2x - 2(2x - 10) = 4
2x - 4x + 20 = 4
- 2x + 20 = 4 ( subtract 20 from both sides )
- 2x = - 16 ( divide both sides by - 2 )
x = 8
substitute x = 8 in equation (3)
y = (2 × 8) - 10 = 16 - 10 = 6
solution is (8 , 6)
The smallest 4 digit odd number. Well think about it. What are the smallest odd number? It is 1 and 0. So the smallest 4 digit odd number is 1,000
Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm
