Answer:
all work is shown and pictured
Answer:
A, D, and E
Step-by-step explanation:
80% off 22 is 17.6
A- 80 ? 100=0.8 x 22= 17.6
D- 0.8 x 22= 17.6
E- 4/5=0.8 x 22= 17.6
Step one =
-3/4x + 25 -1/8x = 1/8x = 1/8x -3 - 1/8x
-7/8x + 25 = -3
Step two =
-7/8x + 25 - 25 = -3 - 25
-7/8x = -28
Step three =
(8/-7) * (-7/8x) = (8/-7) * (-28)
Answer
X = 32
Answer:
<h2>
x=1.8 cm</h2>
Step-by-step explanation:
(2x)²+(x+3)²=(2x+2.4)²
4x²+x²+6x+9=4x²+9.6x+5.76
5x²+6x+9-4x²-9.6x-5.76=0
x²-3.6x+3.24=0
(x-1.8) ²=0
x-1.8=0 => x=1.8 cm
