change 20 in  to ft

20/12 = 1 2/3 ft


4 ft                               x ft

-------                     =    ---------------

5 /3 ft  shadow           120 ft


using cross products

4 * 120 = 5/3 x

480 = 5/3 x

multiply each side by 3/5

480 * 3/5 = x

288 ft

Choose the equation that represents the line passing through the point (2,-4) with a slope of 1/2? y=1/2x+5, y=1/2x-3, y=1/2x-5,
LUCKY_DIMON [66]
Correct answer: <span>y=1/2x-5
</span>
given: point = (2,-4)
slope = 1/2 

Explanation: equation of line is: y = mx + c
where, m is the slope
c is the y-intercept

Now, 
here, y = 1/2x + c
put, x = 2, y = -4
we get, -4 = (1/2).2 + c
or c = -4 - 1
or c = -5 

Hence, equation of line is : y = 1/2x-5

Solve for x: 12x +16y = 6
zubka84 [21]

Answer: x= 1/2- 4/3

At the bottom it says 0.5, so, 1/2= 0.5 and,

4/3= 1.33.....

Step-by-step explanation:

Add '-16y' to each side of the equation.

12x + 16y + -16y = 6 + -16y

Combine like terms: 16y + -16y = 0

12x + 0 = 6 + -16y

12x = 6 + -16y

Divide each side by '12'.

x = 0.5 + -1.3...y

Simplifying

x = 0.5 + -1.3...y
