An airplane flies a distance of 650km at an average speed of 300 km/h. How much time did the flight take?

Answer:

y = 5/18

Step-by-step explanation:

50/90-y=5/18

Lets simplify our fractions

50/90 = 5/9  (divide top and bottom by 10)

5/9 - y = 5/18

Subtract 5/9 from each side

5/9 -5/9 -y = 5/18 - 5/9

-y = 5/18 - 5/9

We need to get a common denominator of 18

-y = 5/18 - 5/9 *2/2

-y = 5/18 -10/18

-y = -5/18

Multiply each side by -1

-1*-y = -5/18 * -1

y = 5/18

Answer:

The equation is y=-3x-2

Step-by-step explanation:

The first we need to know is the equation of a line, and it is y=mx+b

where the m is the slope and b is the interception to the y axis

With the information in the question the slope is -3 and the equation thats equal to m. and the y intercept of -2 thats equal to the b value

then y=-3x-2

Answer:

x=5

Step-by-step explanation:

3x+11=10x-12

We move all terms to the left:

3x+11-(10x-12)=0

We get rid of parentheses

3x-10x+12+11=0

We add all the numbers together, and all the variables

-7x+23=0

We move all terms containing x to the left, all other terms to the right

-7x=-23

x=-23/-7

x=3+2/7
