Answer:
30°
Step-by-step explanation:
let the first angle be x then the second angle is 2x and the third angle is
1.5 × 2x = 3x , then
x + 2x + 3x = 180
6x = 180 ( divide both sides by 6 )
x = 30
The first angle = x = 30°
2x = 56 - 20y => x = 56/2 - 20y/2 => 28 - 10y . . . (1)
-16(28 - 10y) = 92 - 20y
-448 + 160y = 92 - 20y
160y + 20y = 92 + 448
180y = 540
y = 540/180 = 3
From (1), x = 28 - 10(3) = 28 - 30 = -2.
Therefore, x = -2 and y = 3.
Answer: $3.69
Step-by-step explanation:
Laura bought 4 1/3 bushels of apples.
Firs convert this to an improper fraction for easier calculation:
= 13/3 bushels of apples.
If cost $16 altogether, individually they must cost:
= Cost / Quantity purchased
= 16 ÷ 13/3
= 16 * 3/13
= $3.69
<em>Note: You can divide by a fraction by multiplying the inverse of that fraction. </em>
