We have supplementary angles.

I) 2(x+25) +2x-30=180 ⇒ 2x+50+2x-30=180 ⇒ 4x = 160 ⇒ x = 40°

II) 13w+4w+10=180 ⇒ 13w + 4w = 180 - 10⇒ 17w = 170 ⇒ w = 10°

12 = -2x = 4y Help please

ivolga24 [154]

Answer:

x=−2y+6

Step-by-step explanation:

Step 1: Add -12 to both sides.

−2x+12+−12=4y+−12

−2x=4y−12

Step 2: Divide both sides by -2.

−2x /−2 = 4y−12/−2

x=−2y+6

The quotient of the sum of 2t and 2 and twice the cube of s

Vladimir79 [104]

The equation according to the given verbal sentence is $\frac{2 t+2}{2 s^{3}}$ (after solving this $\frac{t+1}{s^{3}}$ ).

Step-by-step explanation:

Rewrite the given verbal sentence and so it will be easier to translate.

Given: The quotient of the sum of 2 t and 2 and twice the cube of s

sum of 2 t and 2 can be written as

2 t + 2

twice the cube of s

$2 s^{3}$

Now, combine the above according to the given verbal. The quotient of the sum of 2 t and 2 and twice the cube of s means,

2 t + 2 divided by $2 s^{3}$

Now, the equation would be $\frac{2 t+2}{2 s^{3}}$

When solving this equation, we get

$\frac{2(t+1)}{2 s^{3}}=\frac{t+1}{s^{3}}$
