x=-5y+3 is the same as x+5y=3
Well you have to convert the pounds to ounces
1 pound = 16 ounces
2oz+40oz+4oz
46oz
37.5 degrees
we know angled like this always have 180 degrees total between the 2. which means we can set up a little equation to solve for x. The equation is (3x+22)+(x-4)= 180. Initially we can take the solid numbers (22 and -4) and get rid of them by taking them to the 180. 180- 22 is 158. 158 + 4 is 162. now we have 3x + x = 162. we combine like terms. means we end up with 4x =162. We now divide by 4 which means we get 40.5. Now we know x is 40.5. Now dbc is just 40.5- 4 which is 37.5.
I'm guessing to probably divide $45,000 by 23 and then multiply that answer by $12,000. I hope this helps
