Ratio and proportion
real:shadow
so the person is 1.8m but the shadow is 4m
so
real:shadow=1.8:4
so
1.8:4=?:14
1.8/4=?/14
times both sides by 14
25.2/4=?
6.3=?
the tree is 6.3 m tall
Answer:
y = 1
x = -3
Step-by-step explanation:
9x + 2y = 3
-x - y = -12 (multiply second equation with 9)
9x + 2y = 3
-9x - 9y = - 108 (add these to up)
-7y = -105
y = 15 use this to find x
9x + 2y ➡ 9x + 30 = 3 ➡ 9x = -27 ➡ x = -3
Hey there!
The LCM of 8 and 12 is 24.
Hope this helps!
The Answer to the problem is X=3 because sice it is equidistant you do 2x+24 = 30 and subtract 24 from 30 then you will get 2x=6 tben you divide 2 frkm both sides and you will have x=3
The degree is 8 ( the value of the highest exponent).
