Answer:
The answer to your question is: letter J is the right answer
Step-by-step explanation:
3x - 4y = 6
Solve for y
Add - 3x in both sides 3x - 3x - 4y = -3x + 6
Simplify -4y = -3x + 6
Divide by -4 -4/-4 y = -3/-4 x + 6/-4
Simplify y = 3/4x - 6/4
y = 3/4 x - 3/2

Answer:
38.57 feets
Step-by-step explanation:
Given that:
Height of monument, h = 300ft
Shadow of monument, s = 210 ft
Shadow of tree, s = 27ft
Height of tree, = x
Using the relation :
Height / shadow = height / shadow
Monument = tree
300 / 210 = h / 27
Cross multiply
300 * 27 = 210 * h
8100 = 210h
h = 8100 / 210
h = 38.57 feets
Answer:
<h2><em><u>ᎪꪀsωꫀᏒ</u></em></h2>
➪x= 3
Step-by-step explanation:
4x-(8-x)-2=9x-20+x-5
=> 4x-8+x-2 = 9x+x-5
=> 5x-10 = 9x-20+x-5
=> -10+5 = 10x-20-5x
=> -5+20 = 5x
=> 15 =5 x
=> 15/5 = x
=> 3 = x
