If x / 2y = 0.4 , A / 5B = 0.25 Then A + y / 5 =…....

shusha [124]

Answer:

$\frac{x}{2y} = \frac{4}{10} \\ 8y = 10x \\ y = \frac{10x}{8} - - - - - 1 \\ \\ \frac{a}{5b} = \frac{25}{100} \\ \frac{a}{5b} = \frac{1}{4} \\ 4a = 5b \\ a = \frac{5b}{4} - - - 2 \\ \\ so \: \: \frac{a + y}{5} \\ = (a + y) \times \frac{1}{5} \\ = ( \frac{5b}{4} + \frac{5x}{4} ) \times \frac{1}{5} \\ = \frac{5b + 5x}{4} \times \frac{1}{5} \\ = \frac{5(b + x)}{4} \times \frac{1}{5} \\ = \frac{b + x}{4} \\ \\ so \: \: \: \frac{a + y}{5} = \frac{b + x}{4}$

If m∠BEC = 9z + 45 in rhombus ABCD, find the value of z. Help me PLEASE!!!! And can you show me how you did it Please!

cupoosta [38]

The diagonals of a rhombus bisect each other at right angles, therefore m∠BEC=90°

9z + 45 = 90
9z = 90 - 45
9z = 45
z = 45/9
z = 5
