\bf \begin{array}{ccll} length&lbs\\ \cline{1-2} 0.8&20\\ x&60 \end{array}\implies \cfrac{0.8}{x}=\cfrac{20}{60}\implies \cfrac{0.8}{x}=\cfrac{1}{3}\implies 2.4=x

Help me solve this. Please, it's math.(I suck at math ngl ︺︹︺ )
fredd [130]

Answer:

<u><em>Vertical angles are</em></u><u><em> congruent</em></u><u><em>, so the</em></u>

<u><em>equation </em></u><u><em>3x-6 = 114</em></u><u><em> can be used to find x.</em></u>

<u><em>The value of x is </em></u><u><em>40</em></u><u><em>.</em></u>

<u><em /></u>

<u><em>Convince Me!</em></u>

<u><em>Why can you use an equation when solving for x in</em></u>

<u><em>the diagram?</em></u>

<u><em>You can use the eqution because they are equal to each other. When they are equal to each other, you can find x by using the equation to simplify and get x alone.</em></u>

Solve using ELIMINATION (with step by step explanation) Please<br><br> 3x+y=-9<br> y=5x+7
Yuki888 [10]

Answer:

<h2>x = -2 (verified by algebra) ✅</h2>

Step-by-step explanation:

Since we are given the value of y, we can replace it with 5x + 7.

We now have: 3x + 5x + 7 = -9

We can now simplify by adding 3x and 5x to get 8x.

8x + 7 = -9

We can subtract 7

8x = -16

And now, we divide by 8

x = -2

We can check to make sure we are correct

3(-2) + 5 (-2) + 7 = -9

-6 + -10 + 7 = -9

-9 = -9 ✅

Find the area of the shaded region in the simplest form
balandron [24]

Answer:

A = 24t² + 2t

Step-by-step explanation:

The shaded area (A) is calculated as

A = area of outer square - area of rectangle

   = (5t)² - t(t - 2)

   = 25t² - t² + 2t

    = 24t² + 2t
