2a + 7b = 0 ⇒ 10a + 35b = 0
3a - 5b = 31 ⇒ 21a - 35b = 217
31a = 217
a = 7
2a + 7b = 0
2(7) + 7b = 0
14 + 7b = 0
7b = -14
b = -2
(x, y) = (7, -2)
1. Associative Property of Addition
2. Addition Property of Equality
3. Division Property of Equality
4. Substitution Property of Equality
5. Multiplication Property of Equality
6. Subtraction Property of Equality
7. Simplify
Sqrt28 = 2*sqrt7. The side of the square is 2*sqrt7
Divide 171 by 3 which equals to 57
Thats the unit rate: 57
It depends on where the sun is but the answer is 22 but my math could be wrong
