Answer:

8/5 or 3.6

Step-by-step explanation:

1.03x + 3.97x = 5x

So in this equation, it would be:

5x - 5 = 13

Subtract 5 from both side:

5x + 5 - 5 = 13 + 5

5x + 0 = 18

5x = 18

Divide both side by 5

5x/5 = 18/5

1x = 18/5

x = 18/5 or 3.6

Hope this help you :3

Answer:

X = \frac{18}{5}, or X = 3.6

Step-by-step explanation:

For this problem we must isolate x

1.03x+3.97x-5=13 | Add 5 to both sides

1.03x+3.97x=18 | Add the x's

5x=18 | Now divide both sides by 5

x=\frac{18}{5}, x=3.6

The table lists how poverty level income cutoffs​ (in dollars) for a family of four have changed over time. Use the midpoint for
frez [133]

The poverty level cutoff in 1987 to the nearest dollar  was $10787.

<h3>How to find a midpoint?</h3>

The midpoint as the point that divides the line segment exactly in half having two equal segments. Therefore, the midpoint presents the same distance between the endpoints for the line segment. The midpoint formula is: \mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right).

For solving this exercise, first you need plot the points in a chart. See the image.

Your question asks to approximate the poverty level cutoff in 1987 to the nearest dollar using the midpoint formula. Note that the year 1987 is between 1980 and 1990, thus you should apply the midpoint formula from data for this year (1987).

\mathrm{Midpoint\:of\:}\left(1980,8429),\:\left(1990,13145):\quad \left(\frac{1990+1980}{2},\:\:\frac{13145+8429}{2}\right)\\\\ \\

\mathrm{Midpoint\:of\:}\left(1980,8429)\:=\left(\frac{1990+1987}{2},\:\frac{13145+3843}{2}\right)\\ \\ =\left(\frac{3977}{2},\:\frac{21574}{2}\right)

\mathrm{Midpoint\:of\:}\left(1980,8429)\:=\=(\frac{3977}{2},10787)

The answer for your question will be the value that you calculated for the y-coordinate. Then, the poverty level cutoff in 1987 to the nearest dollar  was $10787.

The ____ of ____ property allows you to rewrite . xa· xb as xa + b.
gregori [183]
The rule of distributive property allows you to rewrite xa + xb as x (a + b).

So if x = 2, a = 3 and b = 4, xa + xb = x(a + b)
(2 * 3) + (2 * 4) = 2 (3 + 4)
6 + 8 = 14
14 = 14
...and so on. You may try it yourself with different variations.

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more.

∠A and \angle B∠B are vertical angles. If m\angle A=(6x-11)^{\circ}∠A=(6x−11) ∘ and m\angle B=(5x+4)^{\circ}∠B=(5x+4) ∘ , then f
ICE Princess25 [194]

Answer: \angle B=79^{\circ}.

Step-by-step explanation:

When two lines cross each other , then the opposite angles are known  as vertical angles.

Vertical angles are equal.

Here, ∠A and ∠B are vertical angles.

So, ∠A = ∠B

If \angle A=(6x-11)^{\circ} and \angle B=(5x+4)^{\circ}

Then , 6x-11=5x+4

Subtract 5x from both sides, we get

x-11=4

Add 11 on both sides, we get

x=15

Now , \angle B=(5(15)+4)^{\circ}=79^{\circ}

Hence, the measure of \angle B=79^{\circ}.

Find the value of x in the triangle.
Dmitrij [34]

Answer:

X = 65*

Step-by-step explanation:

Each triangle's angles equal 180*. So the equation you would type to find X is

180 - 65 - 50 = X

X = 65
