Answer:

Okay. So first you add 22+28=50.  Then subtract 1,738-50=1,688. Then divide 1,688 by 2 witch should give you an answer of 844 miles each day.              Hope it helped!

Choose the equivalent system of linear equations that will produce the same solution as the one given below. (1 point) 4x − 2y =
goldenfox [79]

Answer:

<h3>Option d) 4x + 2y = 10 and  8x = 16 is correct</h3><h3>Therefore 4x + 2y = 10 and  8x = 16  equations have equivalent solution  (2,1) is same as the solution of given linear system of equations</h3>

Step-by-step explanation:

Given equations are

4x-2y=6\hfill (1)

2x+y=5\hfill (2)

<h3>To find the the equivalent system of linear equations that will produce the same solution as for the given equation :</h3>

First find the solution to the given system of equations by elimination method

Multiply the equation (2) into 2 we get

4x+2y=10\hfill (3)

Now adding the equations (1) and ( 3) we get

4x-2y=6

4x+2y=10

_______________

8x=16

x=\frac{16}{8}

x=2

Therefore the value of x is 2

Substitute the value of x in equation (1) we get

4(2)-2y=6

8-2y=6

-2y=6-8

-2y=-2

y=\frac{-2}{-2}

y=1

Therefore the value of y is 1

Therefore the solution to the given system of equations is (2,1)

<h3>Now to find the equivalent system of equations have same solution (2,1)</h3>

Verify the equations  4x+2y=10\hfill (4) and 8x = 16

From 8x=16

x=\frac{16}{8}

x=2

Therefore the value of x is 2

Substitute x=2 in equation (4) we get

4(2)+2y=10

8+2y=10

2y=10-8

2y=2

y=\frac{2}{2}

y=1

Therefore the value of y is 1

Therefore the solution is (2,1)

<h3>Therefore option d) 4x + 2y = 10 and  8x = 16 equations have equivalent solution  (2,1) is same as the solution of given linear system of equations </h3>

)A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probab
stiv31 [10]

Answer:

40%

Step-by-step explanation:

The probability of the arrow landing on the green section is a 40% chance

This is because there are only 3 sections where one is 50 and the other is 10

To find the green we can create an equation, where x = green section

50 + 10 + x = 100

The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise

60 + x = 100

x = 100 - 60

x = 40
