Standard form : Ax + By = C
y = 4/5x - 2....subtract 4/5 from both sides
-4/5x + y = -2 ....multiply both sides by -5
4x - 5y = 10 <== standard form
Answer:
4:3
Step-by-step explanation:
The number of white socks is: 4
The number of brown socks is: 3
So it says the ratio of white to brown socks is: So you would write/ type, 4:3 to repesent the white to brown socks.

D. (4√(2) - √(2)) × √(2) + (2) × √(18)
3√(2) × √(2) + 2√(2) × 3√(2)
3(2) + 6(2)
6 + 12
18
E. √(3) × (2√(5) + 3√(5)) - √(5) × (√(3) + 2√(3))
√(3) × 5√(5) - √(5) × 2(3)
√(3) × 5√(5) - √(5) × 6
5√(15) - 6√(5)
400+0.1s
400 represents how much she earns per week
0.1 represents the percentage
s represents her weekly sales
0.1s represents how much of the weekly sales she gets to have.(I'm not sure if I worded the last one correctly.)
