Answer:

Step-by-step explanation:

hello

$2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4 \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by \ \ 2\\$

so the solution is 2

$5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4 \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by \ \ 5$

so the solution is 4/5

hope this helps

a flag pole that is 8 feet tall casts a shadow that is 6 ft long a nearby tree casts a shadow that is 21 ft long. How tall is th

Andru [333]

Answer:

The tree is 28 feet tall.

Step-by-step explanation:

It is given that:

Height of flag pole = 8 feet

Shadow of flag pole = 6 feet

Ratio of height to shadow = 8 : 6

Shadow of nearby tree = 21 feet

Height of nearby tree = x

Ratio of height to shadow = x : 21

8 : 6 :: x : 21

Product of means = Product of extremes

6x = 8*21

6x = 168

Dividing both sides by 6

$\frac{6x}{6}=\frac{168}{6}\\x=28$

Therefore,

The tree is 28 feet tall.
