8.9-3.3j=-2.2j+2.3
add 3.3j to both sides
8.9=1.1j+2.3
subtract 2.3 from both sides
6.6=1.1j
divide both sides by 1.1
6=j
Answer:
v = 6/7 + 2/7y
Step-by-step explanation:
<u>Step 1: Distribute</u>
-7(-2v + 5) - 4y = 2(1 - 9) - 7
14v - 35 - 4y = 2 - 18 - 7
Step 2: Add 35 to both sides
14v - 35 + 35 - 4y = -23 + 35 + 4y
14v = 12 + 4y
Step 3: Divide both sides by 10
14v / 14 = 12 + 4y / 14
v = 6/7 + 2/7y
Answer: v = 6/7 + 2/7y
30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.
