90 minutes = 1,5 hours 
Distance = speed * time = 50 * 1.5 = 75 miles (answer).

Answer:

Total distance covered by the car is 75 miles.

Step-by-step explanation:

Given information:

Average speed of car = 50 miles per hour

Time = 90 minutes

We know that, 1 hour = 60 minutes

Using this conversion, convert the time in hours.

Time=\frac{90}{60}=1.5\text{ hours}

The formula for distance is

Distance=Speed\times Time

Distance=50\times 1.5

Distance=75

Therefore total distance covered by the car is 75 miles.

Answer:using elimination to solve for x

9x +6y = 3*134    | Multiplying 1st equation by 3

-4x -6y = -2*146   | Multiplying 2nd equation by -2

   5x = 3*134 - 2*146

   5x = $110

    x = $22,  the cost of the youth ticket

Step-by-step explanation:This question Sets Up two equations with 2 unknowns        

Let x and y represent the cost of the youth and adult ticket respectively

Question states***

3x + 2y = $134    

2x + 3y = $146

X - 5y = 10; (0, -2) Group of answer choices no yes
mr Goodwill [35]
  • Yes, this linear equation is correct on point (0,-2).

Given that:

  • The linear equation

         x - 5y = 10;

  • The point

        (0, -2)

To find

  • We have to prove LHS = RHS

So, according to the question

We have,

The linear equation,

         x - 5y = 10; and point is (0,-2)

From equation,

         x - 5y = 10

Take the left part of given linear equation,

         LHS = x - 5y

Now, putting the values, x = 0 and y = -2.

Then, we will be get.

                = x - 5y

                = (0) - 5 ×(-2)

                = - 5 × -2

                = 10.

So, we can say that

          LHS = RHS.

Where,

           LHS = Left Hand Side.

           RHS =  Right Hand Side.      

We can solve that linear equation in other way,

When we put x = 0, we get y = -2.

So, if we put x = 1, we get y = -9/5.

Similarly, if x = 2, then y = -8/5.

Now, we can say that points (0,-2), (1,-9/5) and (2,-8/5) are lie in the linear equation x - 5y = 10.

Leslie used 20% of a half-gallon (64 ounces) of milk for a recipe. How many ounces of milk were left?
Lady_Fox [76]

Answer:

51.2 ounces.

Step-by-step explanation:

If its 20% of a 64 ounce half gallon, you just need to find the last 80% of the half gallon. Since you know it is 64 ounces you can divide it by 5 which gives you 12.8. 12.8 would be 20% so you just subtract 12.8 from 64 ounces which gives you 51.2.

What is the value of y?<br><br><br> A. y = -1<br><br> B. y = 0<br><br> C. y = 1<br><br> D. y = 3
OverLord2011 [107]

Step-by-step explanation:

The centroid divides the length of each median in 2:1 ratio.

The length of the part between the vertex and the centroid is twice the length between the centroid and the mid-point of the opposite side.

In case of median KM,

K is the vertex and M is the midpoint of the side JL

KT = 2× TM

5y+3 = 2(y+3)

5y+3= 2y +6

5y-2y= 6-3

3y = 3

y= 1
