The CN Tower is 553.33 m (1,815.4 ft) tall from its antenna spire. Meanwhile, the Eiffel Tower only measures 324.00 m (1,063 ft) from its antenna spire.
Answer:
Neither
Step-by-step explanation:
The +10% and -10% cancel each other out, so neither is the answer.
Answer:
![x = -20](https://tex.z-dn.net/?f=x%20%3D%20-20)
Step-by-step explanation:
Use inverse operations and simplification to isolate the variable in the equation.
![-\frac{2}{5}x + 7 = 15\\-7\\\\-\frac{2}{5}x = 8\\](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B5%7Dx%20%2B%207%20%3D%2015%5C%5C-7%5C%5C%5C%5C-%5Cfrac%7B2%7D%7B5%7Dx%20%3D%208%5C%5C)
Now divide the equation by
remember, dividing a fraction is the same as multiplying by the reciprocal. The reciprocal of a fraction is when one switches the places of the numerator (number on top of a fraction bar), and the denominator (number on the bottom of the fraction bar).
![-\frac{2}{5}x = 8\\](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B5%7Dx%20%3D%208%5C%5C)
÷![-\frac{2}{5}](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B5%7D)
![x = 8 * (-\frac{5}{2})](https://tex.z-dn.net/?f=x%20%3D%208%20%2A%20%28-%5Cfrac%7B5%7D%7B2%7D%29)
Simplify,
![x = 4 *(- 5)\\\\ x= -20](https://tex.z-dn.net/?f=x%20%3D%204%20%2A%28-%205%29%5C%5C%5C%5C%20x%3D%20-20)
