In ΔFGH, what is the measure of < H?

kogti [31]

X + x - 1 + 43 = 180. Solve for x. 2x +42 = 180 and 2x = 138. Therefore, x = 69. If x = 69, then angle H is 68 and angle G is 69. 68 + 69 + 43 = 180.

Determine which of the ordered pairs are a part of the solution set of y + 3 < 2x (0, –4)

lorasvet [3.4K]

Answer:

(2,0) and (2,-2)

Step-by-step explanation:

y+3<2x

(2,0) is solution because 0+3<2*2, 3<4 and

(2,-2) because - 2+3<2*2, 1<4

Solve the simultaneous equations. You must show all your working to find x and y. 1/2x -3y = 9 5x y + y = 28

dedylja [7]

Answer:

$\huge\boxed{x = 6 , y = -2}$

Step-by-step explanation:

$\sf \frac{1}{2} x - 3y = 9-----------(1)\\5x + y = 28 ----------(2)$

Taking equation (1)

$\sf \frac{1}{2} x -3 y=9$

Multiplying both sides by 2

$\sf x-6y = 18$

Adding 6y to both sides

$\sf x = 18+6y$

Putting this in (2)

5(18+6y) + y = 28

90 + 30y+y = 28

31y+90-28 = 0

31 y + 62 = 0

31y = -62

Dividing both sides by 31

y = -2

Now,

x = 18 + 6y

x = 18+6(-2)

x = 18-12

x = 6

12,-12x,12x Like terms

Andrew [12]

Answer:

Step-by-step explanation:

Combine like terms *-12x and 12x*

-12x and 12x cancel each other out, therefore your x is gone.

That being said, your answer is 12.
