The answer is B. x > -22
-5x + 20 < 130
-5x < 130 - 20
-5x < 110
-5x/-5 > 110/-5
x > -22
3.2s:8c
4.8s:12c
Therefore, you would need 4.8g of sugar to make 12 cakes. This was solved by using ratios.
Fill in the y of the bottom equation with the top equation because it gives you what Y equals. To answer the question it would be easier to input the top equation into the bottom one. Once you then get the equation for X go to the equation on top and fill in the x to get the y. X=0 Y=2
Could you be a little more specific.
