Answer:
![x=34](https://tex.z-dn.net/?f=x%3D34)
Step-by-step explanation:
*it's kind of hard to read the number in parenthesis though but i think it's 5
both angles have to add up to 180º because they are co-exterior angles on parallel lines.
![2(x+5)+102=180\\2(x+5)=78\\2x+10=78\\2x=68\\x=34](https://tex.z-dn.net/?f=2%28x%2B5%29%2B102%3D180%5C%5C2%28x%2B5%29%3D78%5C%5C2x%2B10%3D78%5C%5C2x%3D68%5C%5Cx%3D34)
Given:
weight of mixture : 1792 ounces
output of mixture : 560 bars of soap
to get the weight per unit, we simply divide by total weight by the total number of output.
1792 oz / 560 bars = 3.2 ounces per bar.
2414 total seats.......221 reserved.....x = non-reserved.....y = remaining seats
y = 2414 - (x + 221)
y = 2414 - x - 221
y = 2193 - x <=====
