1st you distribute whats outaide the fractions 2/3*6 and 2/3*5/6 which would be 4 and 5/9 and then subtract those which would be 4/1 - 5/9 To make denomantor the same you would multiply 4/1 by 9 so it would be 36/9- 5-9= 31/9 which converts to 3 4/9. so your answer is 3 4/9

PLEASE PLEASE HELP !!

Answer:

∠G = 23.3

∠H = 42.8

∠J = 19.9

Step-by-step explanation:

<em>Tan(G) = 0.43</em>

=> G = Tan⁻¹(0.43)

=> <u>∠G = 23.3</u>

<em>Sin(H) = 0.68</em>

=> H = Sin⁻¹(0.68)

=> <u>∠H = 42.8</u>

<em>Cos(J) = 0.94 </em>

=> J = Cos⁻¹(0.94)

=> <u>∠J = 19.9</u>

Hope this helps!

Answer:

a) 2/3p
b) q + 1/2p

Step-by-step explanation:

<u>Given</u>

AB = p
AD = q

a)

DC /AB = 3/2 ⇒
DC = 3/2AB = 3/2p

b)

BC = AD + (DC - AB)
BC = q + (3/2p - p) = q + 1/2p

Given that A varies directly as B and inversely as C and that; A=12 when B=3 and C=2. Find B when A=10 and C=1.5

maria [59]

Answer:

B = 1.875

Step-by-step explanation:

given that A varies directly as B and inversely as C then the equation relating them is

A = $\frac{kB}{C}$ ← k is the constant of variation

to find k use the condition A = 12 when B = 3 and C = 2 , then

12 = $\frac{3k}{2}$ ( multiply both sides by 2 to clear the fraction )

24 = 3k ( divide both sides by 3 )

8 = k

A = $\frac{8B}{C}$ ← equation of variation

when A = 10 and C = 1.5 , then

10 = $\frac{8B}{1.5}$ ( multiply both sides by 1.5 )

15 = 8B ( divide both sides by 8 )

1.875 = B
