8x - 6 - 8 = 4 + 2x
8x - 14 = 4 + 2x
8x = 4 + 2x + 14
8x = 2x + 18
8x - 2x = 18
6x = 18
x = 18/6
x = 3 

*Answer is x = 3 because 18/6 is 3 since 3 * 6 = 18.

First you will distribute
8x - 6 - 8 = 4 + 2x
Then combine like terms
8x - 14 = 4 + 2x
6x = 18
Divide
x = 3

A 3 foot tall globe standing next to a woman cast an 8 ft shadow. if the woman cats a shadow that is 16ft long , then how tall i
My name is Ann [436]

The woman is 6 foot tall

<h3>What is proportion?</h3>

Proportion can be defined as the mathematical comparison of two numbers.

These numbers could be numbers, elements, set or people

From the information given, we have that;

  • The globe is 3 feet and casts a shadow of 8ft
  • The woman cast a shadow of 16ft and is x feet tall

So,

if the globe is 3 foot tall and casts a shadow of 8ft

Then the woman is x foot tall to cast a shadow of 16ft

cross multiply

8x = 24

Make 'x' the subject

x = 48/ 8

x = 6 foot

Thus, the woman is 6 foot tall

jarptica [38.1K]

Answer:

\frac{5}{56} salt does she need for her recipe.
