Answer:

x>4/5

Step-by-step explanation:

<em>Subtract by 5 from both sides of equation.</em>

<em>5-2x-5<8x-3-5</em>

<em>Simplify.</em>

<em>-2x<8x-8</em>

<em>Subtract by 8x from both sides of equation.</em>

<em>-2x-8x<8x-8-8x</em>

<em>Simplify.</em>

<em>-10x<-8</em>

<em>Multiply by -1 from both sides of equation.</em>

<em>(-10x)(-1)>(-8)(-1)</em>

<em>Simplify.</em>

<em>10x>8</em>

<em>Divide by 10 from both sides of equation.</em>

<em>10x/10>8/10</em>

<em>Simplify, to find the answer.</em>

<em>8/10=4/5</em>

<em>x>4/5 is the correct answer.</em>

<em>I hope this helps you, and have a wonderful day! </em>

Answer:

Isolating the x.

Step-by-step explanation:

The first step to solving this problem is to isolate the variable, x.

To do so, subtract 8x and 5 from both sides.

Step #1)

5 - 2x < 8x - 3

5 (-5) - 2x (-8x) < 8x (-8x) - 3 (-5)

-2x - 8x < -3 - 5

-10x < -8

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral.
Nadusha1986 [10]

Here is a reference to the Inscribed Quadrilateral Conjecture it says that opposite angles of an inscribed quadrilateral are supplemental.

Explanation:

The conjecture, #angleA and angleC# allows us to write the following equation:

#angleA + angleC=180^@#

Substitute the equivalent expressions in terms of x:

#x+2+ x-2 = 180^@#

#2x = 180^@#

#x = 90^@#

From this we can compute the measures of all of the angles.

#angleA=92^@#

#angleB=100^@#

#angleC=88^@#

<span>#angleD= 80^@#</span>

After finishing the prep work, Gilberta and María start removing wallpaper at the same time. Gilberta removes the paper at a con
Alexxx [7]

Using linear functions, the inequality that represents when Gilberta has more wallpaper left in her room than María has in hers is: t < 5.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, we consider:

  • The initial amount as the y-intercept.
  • The rate as the slope.

Hence the amounts Gilberta and Maria have left after t hours are given by:

  • G(t) = 35 - 4.3t.
  • M(t) = 30.5 - 3.4t.

Gilberta has more papers when:

G(t) > M(t).

Hence:

35 - 4.3t > 30.5 - 3.4t

-0.9t < -4.5

Multiplying by -1:

0.9t < 4.5

t < 4.5/0.9

t < 5.

Hence the inequality is:

t < 5.
