The original formula is y=kx. k is the constant. That means the constant is 0.2.
Answer:
2:5
Step-by-step explanation:
The ratio can be found by turning both values into either grams or kilograms. For this, I will make them both into grams.
1. 800g is already in grams, so leave it.
2. 2kg is in kilograms, and 1 kilogram = 1000 grams.
3. 2 kilograms is equal to 2000 grams.
4. For this reason, 800g: 2000g can be simplified by making 800g into 2, and 200g into 5.
<u>That is the ratio, 2:5</u>

Answer:
x = 16
Step-by-step explanation:
2x - 3 + 23 + 128= 180
Combine like terms
2x+148 = 180
Subtract 148 from each side
2x+148-148= 180-148
2x =32
Divide by 2
2x/2 =32/2
x = 16
