Answer:
x = 10
Step-by-step explanation:
2) -3x + 17 = -x - 3
4) 20 = 2x
1) -3x + 12 + 5 = -x -3
5) 10 = x
3) 17 = 2x - 3
<u>-3(x - 4) + 5 = -x - 3</u>
<u>-3x + 12 + 5 = -x - 3</u>
<u>-3x + 17 = -x -3</u>
<em>+3x +3x</em>
<u>17 = 2x - 3</u>
<em>+3 + 3</em>
<u>20 = 2x</u>
<u>10 = x</u>

Find the mean ,median, and mode round to the nearest tenth if necessary for 9.3, 8.4, 8.0, 9.1, 9.4, 9.0, 7.8, 9.3, 8.0
Ivenika [448]
Mean-1.6
median-9.0
mode-8.65 8.0 and 9.3=17.3/2 is 8.65
Sin V = opp/hyp
Sin 60 = opp/18
opp = sin 60 x 18
opp = 15.6
opp = 9 root 3
Answer:
D
Answer: 7.5
Form your proportion. Let x be the width of QRST.
Length of ABCD Length of QRST

Width of ABCD Width of QRST
8/5 = 12/x
Solve for x by cross-multiplying.
(8)(x) = (12)(5)
8x = 60
x = 7.5
