A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City. Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at
590 mph.
Which equation is correctly written in standard form to represent this scenario?
0 590a - 550b = 1275
550a +590b = 1275
590a + 550b = 1275
550a - 5906 = 1275

550a + 590b = 1275

Step-by-step explanation:

We use the following relation to solve this question:

In which v is the velocity, d is the distance and t is the speed.

In this question, we find the distance, so we use:

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.

This means that .

Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.

This means that .

Which equation is correctly written in standard form to represent this scenario?

1275 = 550a + 590b

550a + 590b = 1275

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
