Answer:

Step-by-step explanation:

20y - 60 = 5x

add 60 to both sides:

20y = 5x + 60

divide through by 20:

y = (1/4)x + 3

slope = 1/4

y-intercept = (0, 3)

Find values for θ that make each statement true (show steps)
Ksju [112]

Answer:

Step-by-step explanation:

1. sinФ = cos 25

25 ° is in the between 0 and 90°

therefore it can simply represent

cosФ= sin (90-Ф) = sin (90 - 25) = sin 65

2. sin(Ф/3 + 10) = cos Ф

cos Ф = sin (90 -Ф)

sin(Ф/3 + 10) = cos Ф

sin(Ф/3 + 10) = cos Ф = sin(90-Ф)

Ф/3+10=90-Ф

10Ф+3/30 = 90-Ф

10Ф+3 = 30(90-Ф)

10Ф+3 = 2700-30Ф

10Ф+30Ф=2700-3

40Ф = 2697

Ф = 2697 / 40 = 67.425 ≅ 67.4°

The density d of a substance is given by the formula d = m/v, where m is its mass and V is its volume.
Marta_Voda [28]

Step-by-step explanation:

a. d = m/v

m = d × v

b. m = d × v

= 5.01g/cm × 1.2cm

= 6.012g

hopefully this makes sense

18-2x+10=12x solve for x
Scorpion4ik [409]

Answer:

x=2

Step-by-step explanation:

18-2x+10=12x

-2x+18+10=12x

-2x+28=12x

subtract 28 from both sides= -2x=12x-28

subtract 12x from both sides= -14x=-28

divide both sides by -14= x=2

x=2 is your final answer

When 2 lines are coinciding, this means its the same line.
One equation is simply a multiple of the other.

8x = 4x*2
This means the multiplier is 2

5y*2 = 10y

8*2 = 16

The missing values are 10y and 16
