What is the answer? ( 2 - 1 ) ÷ ( - - ) =

The first step I would do is make each fraction an improper fraction if needed. 2 x 8 is 16, and 16 plus 1 is 17. 1 times 10 is 10, plus 3 is 13. Then, I would make each fraction have the same denominator. It may not be the smallest, but 120 will work. Now, solve. 255-156 is 99, keep the denominator the same. 160/130 has a greater absolute value than -12/120, so subtract 12/120 from 160/120 to get 148/120. Now to divide. Keep, change flip. 99*120 is 11880, and 120*48 is 5760. Simplify to get 59/288.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
