Answer:

$5

Step-by-step explanation:

Magazine cost: 5$ each

Eraser cost: X$ each

Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.

 

  • 1(5) + 4(X) = 25

 

  • 5 + 4X = 25

 

  • subtract 5 from both sides

 

  • 4X = 25 - 5

 

  • 4X = 20

 

  • divide both sides by 4

 

  • X = 20/4

 

  • X = 5

  • Each eraser cost 5$

Hope this helps :)

Subtract magazine from total:

25 -5 = 20

Divide by number of erasers:

20/4 = 5

Each eraser cost $5

Answer:

<u>Properties of a rhombus used to solve the following </u>

  • <em>Opposite angles are congruent</em>
  • <em>Diagonals are angle bisectors</em>
  • <em>Diagonals are perpendicular to each other</em>
  • <em>Adjacent angles are supplementary</em>

(30)

  • ∠2 = ∠3 = ∠5 = 27°
  • ∠1 = ∠4 = 180° - (2*27°) = 126°

(31)

  • ∠4 = 70°
  • ∠1 = ∠2 = ∠3 = ∠5 = 1/2(180° - 70°) = 1/2(110°) = 55°

(32)

  • ∠1 = ∠2 = ∠5 = 90° - 26° = 64°
  • ∠3 = 26°
  • ∠4 = 90°

Complete the slope-intercept form of the linear equation that represents the relationship in the table.
nevsk [136]

According to the given table, the slope-intercept equation of the line is given by:

y = -2x + 1

The equation of a line, in <em>slope-intercept</em> form, is given by:

y = mx + b

In which:

  • The slope is m.
  • The intercept is b.

In this problem, we are given two points, (3,-5) and (-2,5).

  • The slope is given by <u>change in y divided by change in x</u>, hence:

m = \frac{5 - (-5)}{-2 - 3} = -2

Hence:

y = -2x + b

Point (3,-5) means that when x = 3, y = -5, which is used to find b.

y = -2x + b

-5 = -2(3) + b

b = 1

Hence, the equation of the line is:

y = -2x + 1

Determine whether this situation is linear or nonlinear? Explain your reasoning
jenyasd209 [6]
You didn't describe the situation so I can't answer.
However: if the graph of the situation is a straight line then the situation is linear, and if the graph is not a straight line then it is nonlinear.
