Answer:
y = -5/8
x = 7/24
Step-by-step explanation:
elimination
12x + 4y = 1 | ×1 |
6x - 2y = 3 | ×2 |
12x + 4y = 1
12x - 4y = 6
_________--
8y = -5
y = -5/8
elimination
12x + 4y = 1 | ×1 |
6x - 2y = 3 | ×2 |
12x + 4y = 1
12x - 4y = 6
_________+
24x = 7
x = 7/24
Answer: 448 hours
Step-by-step explanation:
272 divided by 17 = hourly wage
hourly wage= 16$
448 divided by 16 = 28 weeks

Answer:
Replace the y, z, and x values with real numbers .
0 - 3 = -3
5 + 4 = 9
3 + 4 = 7
It is a 3rd degree monomial, meaning it has only one term.
Hope I helped!
Use the Pythagorean Theorem:
a² + b² = c²
4² + b² = 8.5²
16 + b² = 72.25
b² = 56.25
b = 7.5
