Answer:a

Step-by-step explanation:

Yes, the given table shows a proportional relation with constant of proportionality  1/3.

Two variables x and y are in proportional relation if the relation between  then is in the form y = k x, where k is the constant of proportionality.

Or we can say for all pairs ( x, y ) , y/x = k , k is constant then the table containing (x, y) values shows a proportional relationship.

From given table

When x= 5 , y =[tex]1\frac{2}{3}[/tex] =5/3

Then, y/x = (5/3)/5 = 1/3 =k

When x =6 , y =2

Then, y/x = 2/6 = 1/3 =k

When  x =  7 , y = [tex]2\frac{1}{3}[/tex] = 7/3

Then, y/x = (7/3) /7 = 1/3 =k

When x=8 , y =[tex]2\frac{2}{3}[/tex] = 8/3

Then , y/x = (8/3) / 8  = 1/3 =k

Thus for each pair (x, y) given in the table the ratio y/x is same , this ratio is say k = 1/3

Therefore, for the given table y/ x = k or y =k x with k = 1/3 , and the table  shows a proportional relation with constant of proportionality  1/3.

Answer:

5.77in

Step-by-step explanation:

A cube has 6 square faces, so each face would have area 200 sq in/6=33.33 sq in

Since the area of each face equals the square of the sides, the edge of the cube would be sqrt%2833.33sq+in%29= approx. 5.77 in

Answer:

Yes, they are equivalent, and the second question is B

Step-by-step explanation:

If you add x on both sides of equation A, then it comes up to 5x+2=6, which is equivalent to equation B. For the second question, you are just basically adding a variable to each side, so it is B.

Answer:

If I get 2=3 in solving the system, it means the following:

Step-by-step explanation:

The solution of linear system of equations implies that a point has to be found that holds true on all equations involved.

The system may consist of two equations involving two unknowns or may consist of three equation with three unknowns.

When a system of equation has no solution, the variables are removed in solving the equations and we get an equation or values in the form.

constant = constant

So,

If I get 2=3 in solving the system, it means the following:

Answer:

El orden de forma creciente de los números enteros es:

-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32

Step-by-step explanation:

Ordenar de forma creciente números enteros implica ordenarlos de menor a mayor. Esto es, debes considerar primero el número que posea el menor valor y luego ir ordenándolos a medida que su valor vaya aumentando, para dejar en último lugar al que posea el mayor valor.

Para ordenarlos debes tener en cuenta que:

Entonces, en este caso el orden de forma creciente de los números enteros es:

-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32

that make the equation true.

No solution

Step-by-step explanation:

-x + 5 + 6x = 1 + 5x + 3

Group like terms

-x+6x+5=1+5x+3

Add similar elements:-x+6x=5x

5x+5=1+5x+3

Group like terms

5x+5=5x+1+3

Add the numbers 1+3=4

5x+5=5x+4

Subtract 5 from both sides

5x+5-5=5x+4-5

Simplify

5x=5x-1

Subtract 5x from both sides

5x-5x=5x-1-5x

Simplify

0=-1

The sides are not equal

Answer:

  P = 70 +4x

Step-by-step explanation:

From your previous work with the parking lot, you know its area is ...

  A = 560 +32x

The width of the parking lot extension is (52 -20 -24) = 8 yards, so its area is ...

  extension area = 8P

We want the extension area to be equal to the original area so that adding the extension will double the area:

  extension area = A

  8P = 560 +32x

  P = 70 +4x . . . . . . divide by 8

Step-by-step explanation:

Answer: g*5 + b*10 ≥ 50.

Step-by-step explanation:

Let's define g = number of rings that land in green boxes.

and b = number of rings that land in blue boxes.

For each ring in the green box you earn 5 points, then if there are g rings in the green box, you have g*5 points.

And for the blue is similar, if there are b rings in the blue box, you will have b*10 points.

Then the total number of points that you will get is:

T = g*5 + b*10.

And the minimum that you need to win is 50 points, the inequality will be:

T ≥ 50

or

g*5 + b*10 ≥ 50.

Answer:

To find a, b, and c, rewrite in the standard form ax2+bx+c=0ax2+bx+c=0.

These are the only ones I think

[tex]6\frac{1}{4}[/tex] kilometer:  [tex]1\frac{1}{4}[/tex] minutes and 1 kilometer: 1/5 minutes has unit rate as 5.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The given, ratios are:

4/5 km : 5 minutes

[tex]3\frac{1}{10}[/tex] km: 3/10 minutes

1 kilometer: 1/5 minutes

1/3 kilometer: [tex]1\frac{2}{3}[/tex] minutes

[tex]4\frac{1}{2}[/tex] kilometer: 2 minutes

[tex]6\frac{1}{4}[/tex] kilometer:  [tex]1\frac{1}{4}[/tex] minutes

We need to check which ratios have 5 as unit rate.

[tex]6\frac{1}{4}[/tex] kilometer:  [tex]1\frac{1}{4}[/tex] minutes has unit rate as 5

25/4/5/4

5

1 kilometer: 1/5 minutes

5

Hence, [tex]6\frac{1}{4}[/tex] kilometer:  [tex]1\frac{1}{4}[/tex] minutes and 1 kilometer: 1/5 minutes has unit rate as 5.
