Answer:

x = 3

Step-by-step explanation:

(-2 + 40x) + 62° = 180° (adjacent angles are supplementary)

-2 + 40x + 62 = 180

Add like terms

40x + 60 = 180

Subtract 60 from each side

40x + 60 - 60 = 180 - 60

40x = 120

Divide both sides by 40

40x/40 = 120/40

x = 3

Andrej [43]

Cause 5+3+8, 8+3=11 11+3=14, so 14+3=17 17+3=20, 20+3=23 23+3=26 26+3=29 29+3=32
so its 5, 8, 11, 14, 17, 20, 23, 26, 29, 32

Solve the equation for the y-value and choose whether it is a direct variation or inverse variation.

muminat

Answer:

Step-by-step explanation:

the equation representing direct variation is

y = kx ← k is the constant of variation

The equation representing inverse variation is

y = $\frac{k}{x}$ ← k is the constant of variation

Given

3y = x ( divide both sides by 3 )

y = $\frac{1}{3}$ x ← equation representing direct variation

with k = $\frac{1}{3}$
