Your answer is 51 because you have to trade the 3 and the 5 out with the z and the x so to find your answer you add -8+9+5 then you *3 bc z=3 then you add 7 * 5 so you answer is 51

Answer:

$x = 19$

Step-by-step explanation:

If two lines are perpendicular, they create 4 90° angles. Meaning, in this case, that m<DBC = 90 and m<DBA = 90.

We're given that m<DBE = 2x - 1 and that m<CBE = 5x - 42.

The sum of angles DBE and CBE = m<DBC = 90°

We can add the two angles and set it equal to 90 to find x

$2x - 1 + 5x - 42 = 90\\7x - 43 = 90\\7x = 133\\x = \frac{133}{7} =19$

209 action figures on his wall

380/100 = 3.8
so there would be 3.8 action figures per 1%
then 3.8*55 =209

My name is Ann [436]

Answer:

$v = \dfrac{8}{a(y - 7)}$

Step-by-step explanation:

$y = \dfrac{8}{av} + 7$

Subtract 7 from both sides.

$y - 7 = \dfrac{8}{av}$

Multiply both sides by v.

$v(y - 7) = \dfrac{8}{a}$

Multiply both sides by 1/(y - 7).

$v = \dfrac{8}{a(y - 7)}$
