Answer:

Step-by-step explanation:

<u>8.</u>  The angles are equal, so:

(2x+2) = (3x - 63)

-x = -61

x = 61

Angle (2x+2) is 124°

Angle (3x-63) is 120°

<u>9.</u> The sum of all angles in a triangle is 180°.

The sum of the two unknown angles is 90° [180° - 90° from the right angle°]

(8x+2) + (9x+3) = 90°

17x + 5 = 90°

17x = 85°

x = 5

The two angles are:

(8x+2)  =  42°

(9x+3)  =  48°

Moana sold
Evgesh-ka [11]

9514 1404 393

Answer:

  • Moana: 68 seed packets
  • Afa: 27 calendars

Step-by-step explanation:

Let c represent the number of calendars sold. Then 95-c is the number of seed packets sold. The total revenue is ...

  0.65(95-c) +1.50c = 84.70

  0.85c = 22.95 . . . . . . . . . . . . subtract 61.75

  c = 27

  95 -c = 68

Moana sold 68 seed packets; Afa sold 27 calendars.

<span>2. a) 4x + (4 -x) = 0
</span>   4x + 4 -x = 3x + 4 is not equal to 0. 
<span>  b)  4x + (-4x)  = 0 additive inverse
</span>  c) <span>4x + (1/4x) not equal to zero should use multiplicative inverse
 d) </span><span>4x + x - 4 = 5x - 4 is not equal to zero</span>
