Answer:

ans: D

Step-by-step explanation:

suppose

y = 3x +1 be equation••••••1

and

y = -2x - 4

-y= 2x + 4 be equation ••••••2

add equation 1 and 2 as

y = 3x + 1

-y = 2x + 4

0 = 5x + 5

so ,

5x = - 5

x = - 1

put x In either equation 1 or 2 to get y= - 2

OR,

since given equation intersects each other ,

use substitution method ,

Use proportion to find the answer.

prisoha [69]

Answer

$\boxed {64}$

Detailed Explanation

Let's set up a proportion.

$\frac{3}{4.8} = \frac{40}{x}$

Now that we have set up a proportion we would need to cross multiply.

3*x=3x

40*4.8= 192

Solve for x

$3x=192$

$\frac{192}{3} = 64$

Therefore, the answer would be 64.
