What is the value of X

Mathematics

<u>Answer:</u>

The value of x is 12 cm.

<u>Step-by-step explanation:</u>

From the given figure, we know that the two corresponding lines are parallel and so the two given triangles are congruent to each other.

Therefore, the corresponding sides of these triangles will also be proportional so we can write it as:

\frac{4}{4+16} =\frac{3}{3+x}

\frac{4}{20} =\frac{3}{3+x}

By cross multiplication:

12+4x=60

4x=60-12

4x=48

x=\frac{48}{4}

x=12

Therefore, the value of x is 12 cm.

Answer:

x=12

Step-by-step explanation:

We have been given a graph of similar triangles. We are asked to find the value of x.

Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.

\frac{3}{x+3}=\frac{4}{16+4}

\frac{3}{x+3}=\frac{4}{20}

Upon cross multiplying our equation we will get,

4*(x+3)=3(20)

Upon distributing 4 we will get,

4x+12=60

Let us subtract 12 from both sides of our equation.

4x+12-12=60-12

4x=48  

Upon dividing both sides of our equation by 4 we will get,

\frac{4x}{4}=\frac{48}{4}  

x=12  

Therefore, the value of x will be 12.

<u>Answer:</u>

  • Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.

<u>Step-by-step explanation:</u>

We know that:

  • 48 + 8(b) = Carly's expenditure
  • 10(b) = Carly's expenditure
  • 48 + 8b = 10b
  • B = Boxes of cards

<u>Work:</u>

  • 48 + 8b = 10b
  • => 48 + 8b - 8b = 10b - 8b
  • => 48 = 2b
  • => b = 24

<u>Now, let's substitute the value of b into any equation.</u>

  • 10(24)
  • => 240

<u>Hence, Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.</u>

Hoped this helped.

Explain how to determine whether a point is a solution to a linear inequality?
Orlov [11]

Answer:The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.

Example

Is (1, 2) a solution to the inequality

2x+3y>1

2⋅1+3⋅2>?1

2+5>?1

7>1

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.

Step-by-step explanation:
