Answer:

\huge{\boxed{\sf{ 2y^{2} - 9 }}}

Step-by-step explanation:

( - 3y^{2} - 8 ) - ( - 5y^{2}+ 1 )

While subtracting , sign of each term of the second expression changes.

⇒- 3y^{2} - 8 + 5y^{2} - 1

Combine like terms : -3y^{2} and 5y^{2}

Like terms are those which have the same base.

⇒2y^{2} - 8 - 1

Remember : The negative integers are always added but posses the negative ( - ) sign.

⇒2y^{2} - 9

Hope I helped!

Best regards !

Find yhe difference 2/5 - 3/10
sp2606 [1]
You need common denominators to add or subtract fractions. If you multiple (2/5) by 2 to both the top and bottom, you get (4/10). Now you just subtract the top numbers, or numerators. 4 - 3 = 1. Answer: 1/10.

The three angles of a triangular flag are x, twice the complement of x, and one-half the supplement of x
Angelina_Jolie [31]
Let x be the first angle
y be the second angle
z be the third angle.

for the second angle, complementary angles are angles sum are 90 degrees
y = 2 ( 90 - x )
y = 180 - 2x
2x + y = 180
for the third angle, supplementary angles are angles sum are 180 degrees
z = 0.5( 180 - x )
z = 90 - 0.5x
0.5x + z = 90

then the sum of a triangle is 180
x + y + z = 180
so x = 60
y = 60
z = 60

(BRAINLYST FOR ANSWER IF CORRECT) What is the value of c?<br> c+15°<br> c–16°<br> c–18°
asambeis [7]

Answer:

c = 49°

Step-by-step explanation:

Inside of the triangle angles:

  • c–18°
  • c–16°
  • 180°-(c+15) → -c+165

these angles sum up to total 180° angle

-c+165+c-16°+c–18° = 180

c +131 = 180

c = 180° - 131°

c = 49°
