Answer:
x = 2
Step-by-step explanation:
Given
8(4 - x) = 7x + 2 ← distribute parenthesis on left side
32 - 8x = 7x + 2 ( subtract 7x from both sides )
32 - 15x = 2 ( subtract 32 from both sides )
- 15x = - 30 ( divide both sides by - 15 )
x = 2
Answer:
The 3 friends ate 1/5 of the pie.
Step-by-step explanation:

<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by
Substituting the coordinates of the point C in the above formula, we get;
Therefore, the coordinates of the point C' is (-1,2)
Answer:
26
Step-by-step explanation:
The two angles shown are a linear pair. Their sum is 180°.
(4z -8)° +(3z +6)° = 180°
7z = 182 . . . . . . . . . divide by °, add 2
z = 26 . . . . . . . . . . divide by 7
