You know you have two hours which will be the whole number. Then you take 36min and put it over 60min (total number of min in an hour) and you simplify by 6 to get 6/10 which can be simplified again to 3/5 so your final mixed number is
2 and 3/5 hours

Answer:

<em>x = 17°, m∠ A = 114°</em>

Step-by-step explanation:

We can tell that these pair of angles are corresponding, provided;

Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,

m∠ A = m∠ B ⇒ Substitute values of A and B,

6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,

3x + 12 = 63 ⇒ Subtract 12 on either side of equation,

3x = 51 ⇒ Divide either side by 3,

<em>x = 17 </em>⇒ Substitute value of x to solve for m∠ A,

m∠ A = 6 * ( 17 ) + 12,

m∠ A = 102 + 12,

<em>m∠ A = 114</em>

<em>Solution; x = 17°, m∠ A = 114°</em>

Two equations given. We have to find the solution sets for the equations.

y = -x²-2x+8 and y = 2x +11

There are 3 steps given. As both equations are equal to y, so we can equate the x parts.

-x²-2x+8 = 2x+11

0 = x²+4x+3

0 = (x+1)(x+3)

Now we have to use zero product property to solve this. If multiplication of two terms equal to 0, we can set each of them equal to 0.

x+1 = 0 , x+3 = 0

When, x+1 =0, by moving 1 to the other side we will get x = -1.

When x+3 =0, by moving 3 to the other side we will get x =-3

Now for the two values of x, we have to find y .

When x = -1, by plugging in the value to the second equation we will get,

y = 2x+11 = 2×(-1)+11 = -2 +11 = 9

So for x =-1, y =9.

The solution set is (-1, 9)

Now when x = -3, by plugging in the value to the second equation we will get,

y = 2x+11 = 2×(-3) +11 = -6+11 = 5

So for x = -3, y = 5

The solution set is (-3,5)

Therefore, the solutions for the system of equations are (-3, 5) and (-1, 9)

So the third option is correct.
