Answer:
so x=5y

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

**Answer:**

2

**Step-by-step explanation:**

cause 20 percent of 10 is 2 lol

**Answer:**

334

**Step-by-step explanation:**

Answer:334

Step-by-step explanation:

Origine = (0 ; 0)

0 > 3*0 - 9

0 > 0 - 9

0 > - 9

__It's true.__

0 > 3*0 - 9

0 > 0 - 9

0 > - 9

True.

14,000 because 494 would round down since it is not above 500.

**Answer:**

38.7°

**Step-by-step explanation:**

∆ = Tan-1(opposite/ Adjacent)

=Tan-1(8/10)

= 38.66°

= 38.7° to n nearest tenth

point slope

y-y1=m(x-x1) where slope=m and you are given the point (x1,y1)

slope=3/2

point is (-5,1)

y-1=(3/2)(x+5)

if you wan in slope intercept

distribute

y-1=3/2x+15/2

add 1

y=3/2x+17/2

y-y1=m(x-x1) where slope=m and you are given the point (x1,y1)

slope=3/2

point is (-5,1)

y-1=(3/2)(x+5)

if you wan in slope intercept

distribute

y-1=3/2x+15/2

add 1

y=3/2x+17/2
