Answer: 5
Steps:
5x - 2y = 30
5(8) - 2y = 30
40 - 2y = 30
-2y = 30 - 40
-2y = -10
y = -10/-2
y = 5
I would appreciate the brainliest if this answer was correct and the steps were clear and helpful! :)
Answer:
B = 68
Step-by-step explanation:
(6-2)×180 = 720
69+108+135+204+b+2b=720
516+3b=720
3b=720-516
3b=204
b= 68
Shadow of the flagpole=23.5f
Sf=23.5
shadow of gilbert=7.5f
Sg=7.5
height of gilbert=5.5f
hg=5.5
Sf/hf=Sg/hg
23.5/hf=7.5/5.5
23.5*5.5/7.5=hf
(47/2*11/2)/7.5=hf
(517/4)/(30/4)=hf
(517*4)/(4*30)=hf
517/30=hf
17+7/30=hf
17.233.. feet=height of flagpole
