30% off
theh shirt is 22.40 after discount
original=100%
original-discount=22.40
100-30=70%
22.40=70%
percent means parts out of 100
22.40=70/100 of original
multiply both sides by 100/70 to clear fraction
2240/70=original
32=original
original=$32.00

0.1 x 26.40 = 2.64
So the final answer is 2.64
Solution:
<u>It should be noted:</u>
- Opposite sides of a rhombus are always equal.
- Opposite angles of a rhombus are always equal.
<u>Thus:</u>
- (-y - 10) = 90°
- 3z - 3 = 90°
- 4x - 2 = 90°
<u>Finding x:</u>
- 4x - 2 = 90°
- => 4x = 90 + 2
- => 4x = 92
- => x = 23
<u>Finding y:</u>
- (-y - 10) = 90°
- => -y - 10 = 90°
- => -y = 100
- => y = -100
<u>Finding z:</u>
- 3z - 3 = 90°
- => 3z = 90 + 3
- => 3z = 93
- => z = 31
Sorry for the delay but I answered your question and the answer is -6xsquare +11x-4
