#1

First step is to divide the cookies by the required cups of sugar to find out how many cookies 1 cup could make: 

48/3 = 16 

Now, that we know that 1 cup can make 16 cookies, multiply 16 by the 5 cups of sugar she has:

16 x 5 = 80 

That makes #1 B.)


#2
With number two, divide the original amount by the new amount of fudge: 

192/64 = 3 

Now multiply 1.5 by 3

1.5 x 3 = 4.5 

That makes #2 A.)

If the straight-line distance from her home to the university is 10. 3 km in a direction 25. 0° south of east, what was her aver
Paladinen [302]

34.3 Km /h was her average velocity in km/h.

What is average velocity?

  • The change in position or displacement (x) divided by the time intervals (t) during which the displacement happens is the definition of average velocity.
  • Based on the direction of the displacement, the average velocity might either be positive or negative. Meters per second (m/s or ms-1) is the SI measure for average velocity.
  • The displacement of a body, or the shortest distance it must go during a trip, is calculated as the displacement multiplied by the time interval over which it covered that distance.

average velocity = Displacement / time taken

            V = d/ l

V = 10.3 Km/0.300m = 34.3Km

I have to get this so I pass help plz
pshichka [43]

Answer:

\boxed{\sf x=-2}

\boxed{\sf y=-4}

Step-by-step explanation:

<u>First, Let's  solve for x in -2x+2y=-4:</u>

\sf -2x+2y=-4

<u>Subtract 2y from both sides:</u>

\sf -2x+2y-2y=-4-2y

\sf -2x=-4-2y

<u>Divide both sides by -2:</u>

\sf \cfrac{-2x}{-2}=-\cfrac{4}{-2}-\cfrac{2y}{-2}

\bold{ x=y+2}

<u>Now, we'll substitute x=y+2 to 3x+3y=-18:</u>

\sf 3x+3y=-18

→ let x=2+y

\sf 3\bold{(2+y)}+3y=-18

<u>Simplify:</u>

\sf 6+6y=-18

<u>Now, let's solve for y in 6+6y=-18</u>

\sf 6+6y=-18

<u>Subtract 6 from both sides:</u>

\sf 6+6y-6=-18-6

\sf 6y=-24

<u>Divide both sides by 6:</u>

\sf \cfrac{6y}{6}=\cfrac{-24}{6}

\bold{ y=-4}

<u>Now, substitute y=-4 into x=2+y:</u>

\sf x=2+y

→ let y = -4

\sf x=2+\bold{-4}

\bold{x=-2}

Therefore, x=-2 and y=-4.
