Step-by-step explanation:

Solve : -2x - 10 =15

-2x - 10 = 15

-2x = 15 + 10

-2x = 25

x = -25/2

Answer: $\Large\boxed{x=40^\circ}$

Step-by-step explanation:

Given information

∡ 1 = 90°

∡ 2 = 50°

∡ 3 = x°

Total Angle = 180° (Triangle angle sum theorem)

Given formula

∡ 1 + ∡ 2 + ∡ 3 = Total Angle

Substitute values into the formula

(90) + (50) + (x) = (180)

Combine like terms

140 + x = 180

Subtract 140 on both sides

140 + x - 140 = 180 - 140

$\Large\boxed{x=40^\circ}$

Hope this helps!! :)

in a poll 303 students voted . nominee d received 2/3 of the votes how many votes did nominee d receive

Dmitry_Shevchenko [17]

Answer:

Nominee d receive 202 votes.

Step-by-step explanation:

Given : In a poll 303 students voted. Nominee d received $\frac{2}{3}$ of the votes.

To find : How many votes did nominee d receive ?

Solution :

The number of votes = 303

Nominee d received $\frac{2}{3}$ of the votes.

i.e. $n=\frac{2}{3}\times 303$

$n=2\times 101$

$n=202$

Therefore, nominee d receive 202 votes.

Eliminate the parameter. X=sqrt of t y = 2t+5

tankabanditka [31]

X = sqrt
t = x^2

y = 2t + 5
2t = y - 5
t = (y - 5)/2

so x^2 = (y - 5) / 2

2x^2 = y - 5

y = 2x^2 + 5
