4y/5b=L+s solve for B

krek1111 [17]

Answer:

$b = \frac{4y}{5l + 5s}$

Step-by-step explanation:

$\frac{4y}{5b} = l + s$

multiplying through by the L.C.M. which is 5b

$\frac{4y}{5b} \times 5b = (l + s) \times 5b$

cancel out

4y =5bL+ 5bs

factorizing b out

4y=b ( 5L +5s ).

making be the subject by dividing through by ( 5L+ 5s )

$\frac{4y}{5l + 5s} = \frac{b(5l + 5s)}{5l + 5s}$

$b = \frac{4y}{5l + 5s}$

Answer:

${ \bf{ \sec( \theta) = \frac{10}{6} }}$

Step-by-step explanation:

${ \boxed{ \bf{ \cos( \theta) = \frac{adjacent}{hypotenuse} }}}$

Adjacent = 6

Hypotenuse = 10

${ \sf{\sec( \theta) = \frac{1}{ \cos( \theta) } }}$

therefore:

${ \sf{ \sec( \theta) = \frac{hypotenuse}{adjacent} }} \\ \\ { \sf{ \sec( \theta) = \frac{10}{6} }}$
