4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6(9-3x) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
Answer:
A
Step-by-step explanation:
Answer:
DE ≈ 16.1, ∠E ≈ 60.3°, ∠D ≈ 29.7°
Step-by-step explanation:
use pythagorean theorem:
DE² = 8² + 14² => DE = √8² + 14² ≈ 16.1
use inverse tangent function:
∠E =
(14/8) ≈ 60.3°
∠D =
(8/14) ≈ 29.7°
Answer:
They are equal.
Step-by-step explanation:
5 pounds = 80 ounces
Formula: multiply the value in pounds by the conversion factor '16'.
So, 5 pounds = 5 × 16 = 80 ounces.
