Answer:
∠ K = 35° and ∠ L = 105°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let ∠ K = x then ∠ L = 3x
Sum the angles and equate to 180
3x + x + 40 = 180, that is
4x + 40 = 180 ( subtract 40 from both sides )
4x = 140 ( divide both sides by 4 )
x = 35
Thus
∠ K = 35° and ∠ K = 3x = 3 × 35 = 105°
Answer:
0.435 pounds
Step-by-step explanation:
There are 16 ounces in one pound. Use that conversion to find your answer.
Bottle 1 = $1.92 & 12 ounces
Bottle 2 = $2.40 & 16 ounces
Bottle 1
If 12 ounces costs $1.92, to determine the price of 1 ounce we divide $1.92 by 12.
$1.92 ÷ 12 = $0.16 per ounce for bottle 1.
Bottle 2
If 16 ounces costs $2.40, to determine the price of 1 ounce we divide $2.40 by 16.
$2.40 ÷ 16 = $0.15 per ounce for bottle 2.
Therefore we can determine that Bottle 2 is cheaper per ounce than Bottle 1.
-2(9 - x - 7)
= -2(2 - x)
= -4 + 2x
Answer:
-4 + 2x
