hi as a person who is taking geometry, i think i can help

Answer:

7x-3=5x+1 ->x=2

Step-by-step explanation:

to find the x, you would put both equations together like how it is shown above, then try and get x to one side

7x-3=5x+1

   +3      +3

7x=5x+4

-5x -5x

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER
ozzi

Answer:

\sf x=\boxed{18.21}

Step-by-step explanation:

Assuming this is a right triangle.

<u>Trigonometric ratios</u>

\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle
  • H is the hypotenuse

Given:

  • \theta = 35°
  • O = x
  • A = 26

\implies \sf \tan(35^{\circ})=\dfrac{x}{26}

\implies \sf x=26\tan(35^{\circ})

\implies \sf x=18.20539599...

Therefore, x = 18.21 (nearest hundredth)

Exercise 34.

4t+72\geq  400 and t\leq82.

Exercise 35.

30t-4.

<h2>Step-by-step explanation:</h2>

<h2><u>Exercise 34.</u></h2>

1. Forming the inequality.

Let's make the left side be a calculation of the total earning based on the number of tickets sols. Also, let's make the right side the cost of the dance to compare and find an adecuate minimum value of x.

4t+72\geq  400.

<em>We use the </em><em>"greater or equal to"</em><em> symbol because the side of x expresses the earning of the committee, and these earnings will have to be equal or greater than the cost of the dance to be able to organize the dance.</em>

2. Solving the inequality.

4t+72\geq 400\\ \\4t\geq 400-72\\ \\4t\geq 328\\ \\t\geq\frac{328}{4} \\ \\t\geq82

3. Express your results.

t\leq82, therefore, the dance committee will have to sell at least 82 tickets to be able to cover the cost of the dance.

<h2><u>Exercise 35.</u></h2>

2-6(-5t+1)

<em>Apply the associative property of multiplication.</em>

<em>Rule to be applied: </em>a(b+c)=ab+ac.

2+(-6)(-5t)+(-6)(1)=\\ \\2+30t-6\\ \\30t-4

Result.

30t-4.
