8o + 12p = 382 12o + 8p = 388 What does p equal?

shutvik [7]

For this case we have a system of two equations with two variables:

Clear "o" from the first equation:

$8o = 382-12p\\o = \frac {382-12p} {8} = \frac {191-6p} {4}$

We substitute in the second equation:

$12 (\frac {191-6p} {4}) + 8p = 388\\3 (191-6p) + 8p = 388\\573-18p + 8p = 388\\-10p = 388-573\\-10p = -185\\p = \frac {185} {10}\\p = 18.5$

ANswer:

$p = 18.5$

if a and b are acute angles such that sinA=4/5 and cosB=12/13, calculate, without using tables: sin(a-b)

kolbaska11 [484]

$\sin \alpha = \frac{4}{5} \\ \cos \alpha = \sqrt{1-\sin^2 \alpha }= \sqrt{1- \frac{16}{25} } = \sqrt{ \frac{9}{25} }= \frac{3}{5} \\ \\ \cos \beta = \frac{12}{13} \\ \sin \beta = \sqrt{1-\cos^2 \beta }= \sqrt{1- \frac{144}{169} } = \sqrt{ \frac{25}{169} }= \frac{5}{13}$

$\\ \\ \sin (\alpha- \beta ) =\sin \alpha \cos \beta -\cos \alpha \sin \beta = \frac{4}{5}\times \frac{12}{13}- \frac{3}{5}\times \frac{5}{13} = \frac{48}{65}- \frac{15}{65}= \frac{33}{65}$

Answer:
sin(α-β) = 33/65

Solve 9(7x-2) = 5 (10x - 1)

stellarik [79]

Step-by-step explanation:

9(7x-2) = 5 (10x - 1)

63x-18=50x-5

63x-50x=-5+18

13x=13

x=13/13

x=1
