Answer:
6
Step-by-step explanation:

-5 1/4 is a mixed fraction. so we convert it into improper fraction


negative and negative becomes positive

Both fractions have same denominators. so we can combine the numerators

Divide the fraction

Answer:
x = 10
Step-by-step explanation:
a² + b² = c²
6² + 8² = c²
36 + 64 = 100
√100 = ±10
x = 10
Answer:
y = 250x + 1000
Step-by-step explanation:
we know, it is a linear function.
so, y = ax + c
we have multiple data points all on the line.
(4,2000)
2000 = a×4 + c, => c = 2000 - a×4
(7,2750)
2750 = a×7 + c
=> 2750 = a×7 + 2000 - a×4 = a×3 + 2000
=> 750 = a×3
=> a = 250
=> c = 2000 - 250×4 = 2000-1000 = 1000
V=lwh, so try to solve it that way.
