Answer:

$\sf \dfrac{2a+1}{6}$

explanation:

$\hookrightarrow \sf \dfrac{2a-2}{4} -\dfrac{a-4}{6}$

make the denominator same

$\hookrightarrow \sf \dfrac{3(2a-2)}{12} -\dfrac{2(a-4)}{12}$

join both fractions together

$\hookrightarrow \sf \dfrac{3(2a-2-2(a-4))}{12}$

expand the integers

$\hookrightarrow \sf \dfrac{6a-6-2a+8}{12}$

simplify

$\hookrightarrow \sf \dfrac{4a+2}{12}$

Final answer

$\hookrightarrow \sf \dfrac{2a+1}{6}$

Y is directly proportional to 1 over the square root of x if y = 7 when x = 36 find y when x = 4

Alecsey [184]

Step-by-step explanation:

y |X(the sign for protionality) 1/√x

y = 7 when x = 36

y = k/√x

7 = k/√36

7 = k / 6 cross multiply

k = 7×6

k = 42

find y when x is 4

y = 42/√x

y = 42/√4

y = 42/2

y = 21
