Answer:

125°

Step-by-step explanation:

Accumulate every detail given:

720 = 120+100+120+120+ (x+10) + x

720 = 120+100+120+120+2x+10

720=470+2x

Flip the equation to avoid negative equation

470+2x=720

2x=720

x=250/2

x=125

125 Is the final answer

Which of the following is the solution set to the inequality −25x+14>20?

Bezzdna [24]

Answer:

Option C. $x < -15$

Step-by-step explanation:

<u><em>The correct inequality is</em></u>

$-\frac{2}{5}x+14 >20$

Solve for x

subtract 14 both sides

$-\frac{2}{5}x+14-14 >20-14$

$-\frac{2}{5}x >6$

Multiply by -1 both sides

$\frac{2}{5}x < -6$

Multiply by 5/2 both sides

$x < -6(\frac{5}{2})$

$x < -15$

HELP ME PLEASE!!!

Kobotan [32]

Answer:

$x=2 , y=1$

Step-by-step explanation:

Since the second equation is fully simplified and we know what x equals, we plug the entire equation of x in for x in the top equation:

$5(3y-1)+10y=20$

Now solve for y.

$y=1$

Now plug y back into the bottom equation and solve for x.

$x=3(1)-1$

$x=2$
