What is the the value of x? Enter uour answer in the box. 91°, 8x+3°,10x-4°
zzz [600]

Answer:

x = 5 is the right answer.

Step-by-step explanation:

As we know sum of all angles in a triangle is 180°.Therefore in this question we will form an equation.

Sum of all the angles of a triangle = 180

91 + 10x - 4 +8x +3 = 180

90 + 18x = 180

18x + 90 - 90 = 180 - 90

18x = 90

x = 90÷18 = 5

Therefore x = 5 is the right answer.

katrin [286]

Answer:

Step-by-step explanation:

3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)

as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm

I'm guessing that it is...  soooo distribute the minus sign

= 3a^4 - 2a^2 +5a -10  -2a^4 -4a^2 -5a +2

= a^4 -6a^2 -8   :)  voila that's your answer

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
