Step-by-step explanation:

My math is terrible but I think u should eliminate and substitute.

I think the answer is:2x-4y=13

START BY USING BODMAS

  1. <em>Brackets</em>
  2. <em>of</em>
  3. <em>division</em>
  4. <em>multiplication</em>
  5. <em>addition</em>
  6. <em>subtraction</em>

<em>y</em><em>=</em><em>-</em><em>(</em><em>10</em><em>)</em><em>+</em><em>6</em><em>x</em><em>-</em><em>3y</em><em>=</em><em>-</em><em>4x</em><em>-3</em>

<em>{</em><em>3</em><em>+</em><em>10</em><em>=</em><em>13</em><em>}</em>

<em>{</em><em>3y</em><em>+</em><em>y</em><em>=</em><em>4y</em><em>}</em>

<em>{</em><em>6x</em><em>-4x</em><em>=</em><em>2x</em><em>}</em>

<em>4y</em><em>=</em><em>+</em><em>2x</em><em>-13</em>

<em>=</em><em>2x</em><em>-4y</em><em>=</em><em>13</em><em> </em>

<em>I'M</em><em> </em><em>NOT</em><em> </em><em>SURE</em><em> </em><em>OF</em><em> </em><em>THE</em><em> </em><em>ANSWER</em><em> </em><em>THOUGH</em>

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for t
telo118 [61]

We are given displacement = 20 meters.

Time given = 4.7 seconds.

Velocity = 4.3 m/s.

Please note : Velocity is a vector quantity. A vector quantity depends on magnitude and direction as well.

We are given magnitude of displacement = 20 meter and time 4.7 seconds but the direction is missing there.

If it would be in forward direction it would be positive and if it would be in backward direction, it would be of negative.

Therefore, <u>"B)the direction"</u> is correct option.

Someone help me asap math 10

Answer:

x ≈ 25.4 Km

Step-by-step explanation:

Using the tangent ratio in the right triangle on the right

tan54° = \frac{opposite}{adjacent} = \frac{opp}{17} ( multiply both sides by 17 )

17 × tan54° = opp , thus

opp ≈ 23.4

-------------------------------------------

Using the cosine ratio in the right triangle on the left

cos23° = \frac{adjacent}{hypotenuse} = \frac{23.4}{x} ( multiply both sides by x )

x × cos23° = 23.4 ( divide both sides by cos23° )

x = \frac{23.4}{cos23} ≈ 25. 4 Km ( to the nearest tenth )

∠A and ∠B are vertical angles. If ∠A=8x+14 and ∠B=2x+50, what is m∠B?
Maslowich

Answer:

∠B = 62°

Step-by-step explanation:

Because ∠A and ∠B are vertical angles they are equal hence we can write

∠A = ∠B

8x + 14 = 2x + 50

Now we have to solve for x

To do so, subtract 2x on both sides of the equation:

6x + 14 = 50

Now, subtract 14 on both sides of the equation

6x = 36

Now, divide 6 on both sides of the equation

x = 6

To find m∠B you have to you have to plug in x = 6 back into the ∠B equation

∠B = 2(6) + 50

∠B = 62°
