A superhero can fly from New York to Los Angeles in 30 minutes. The distance from New York to Los Angeles is approximately 2450

bulgar [2K]

Answer:

So the superhero covers 2450 miles in 30 minutes or 1/2 hour

Thus, he/she will cover (2450 x 2) miles in 1 hour

Therefore the answer is his/her velocity is (2450 x 2) miles/hour = 4900 miles/hour.

Hope this helps!

5( x-3 ) + 2x =41<br> What is x?

Valentin [98]

Answer:

Step-by-step explanation:

5 ( x - 3 ) + 2x = 41

5x - 15 + 2x = 41

5x + 2x - 15 = 41

7x - 15 = 41

7x = 41 + 15

7x = 56

x = 56 / 7

x = 8

Please help me, I'm doing a test.

Tju [1.3M]

Answer:

(3,4)

Step-by-step explanation:

first you're going to solve the equation -2x

your equation should now be: $\left \{ {{-2x+3y\\=6} \atop {-2x=2-2y}} \right.$

next you're going to substitute the given value of -2x into the equation $-2x+3y=6$

so your equation should now be: $2-2y+3y=6$

next you're going to solve the equation for y

equation should now be: y=4

than you're going to substitute the given value of y into the equation $-2x=2-2$ × $4$

then you're going to solve the equation for x

your equation should now be: x=3

then the possible solution of the system is the order pair: (x,y)=(3,4)
