The answer is 82.4 because when u divide you get 82.4
And that becomes 82.40
Try 5x - 8 + 43 = 90
or: 5x - 8 + 43 = 180
or try this: 5x - 8 = 43
solve for x
don’t forget to plug the number back in
Answer:
x=-11\5+13\5i-iy
y=ix+(13\5+11\5i)
Step-by-step explanation:
x+yi=-7+3i\2+i
x+yi=\frac{\left(-7+3i\right)\left(2-i\right)}{\left(2+i\right)\left(2-i\right)}
x+yi=-11\5+13\5i
x=-11\5+13\5i-yi
x=-11\5+13\5i-iy
x+yi=\frac{-7+3i}{2+i}
x+yi=\frac{\left(-7+3i\right)\left(2-i\right)}{\left(2+i\right)\left(2-i\right)}
x+yi=\frac{-11+13i}{5}
x+yi=-\frac{11}{5}+\frac{13}{5}i
yi=-\frac{11}{5}+\frac{13}{5}i-x
\frac{iy}{i}=\frac{-\frac{11}{5}+\frac{13}{5}i-x}{i}
y=\frac{-\frac{11}{5}+\frac{13}{5}i-x}{i}
Answer: If you take 4 times 6 you get 24, so take 3*6 to get an 18-foot shadow. 4:3=24:18. I hope this helps. I'm not sure what your choices are, though.
