Answer:

4 cm (A)

Step-by-step explanation:

triangle BAC is just a larger version of triangle EAD. given that ED is 5cm, and BC is 10cm, triangle BAC must be twice the size of EAD. since the ratio of AD to ED is 4:5, and BC is twice the size, all we need to do is multiply both sides by 2 to find length AC. 4*2 = 8. now we can subtract length AD from AC to get CD. 8 - 4 = 4.

sorry if what i wrote is a little confusing

a video game club has 42 members the number of high school members is six less than twice the number of middle school memebers w

jonny [76]

Answer:

26

Step-by-step explanation:

h represents highschool members

m represents middle school members

42 = h+m

h = 2m-6

Substitute h for 2m-6 in first equation:

42 = (2m-6)+m

Solve for m:

42 =3m-6

48 = 3m

m = 16

Subsitute 16 for m in second equation:

h = 2(16)-6

Solve for h:

h = 32-6

h = 26

Please helppp<br> solve for y

erastovalidia [21]

Answer: $y=\frac{-x}{w-3}$

Step-by-step explanation:

To solve for y, we want to isolate y.

$w=\frac{3y-x}{y}$ [multiply both sides by y]

$yw=3y-x$ [subtract both sides by 3y]

$yw-3y=-x$ [factor out y]

$y(w-3)=-x$ [divide both sides by (w-3)]

$y=\frac{-x}{w-3}$

Now, we know that $y=\frac{-x}{w-3}$ .
