Answer:

  5x +4y

Step-by-step explanation:

The perimeter of a triangle is the sum of side lengths. That fact can be used to find z, the length of the third side.

  (2x +3y) +(5x -2y) +z = 12x +5y . . . . sum of sides is perimeter

  z = (12x +5y) -(7x +y) . . . . . . . . . . . . subtract (7x+y) from both sides

  z = 5x +4y . . . . . . . . . collect terms; the length of the third side

The third side of the triangle is (5x +4y).

Answer:

pair of pants = $53

Step-by-step explanation:

s = shirts

p = pair of pants

eq = equation

eq 1:          7s + 5p = 517

eq 2:           s + p = 89

multiply the equation 2 by 7

eq 3:        7s + 7p = 623

negate equation 1 and add it to the eq 3

      7s + 7p = 623

+    -7s - 5p = -517

             2p = 106

               p = 53

Answer:

  see the attachments for the graph, and a spreadsheet with midpoints and slopes

Step-by-step explanation:

We are given the coordinates of the vertices of a triangle, and asked to find the parameters of the perpendicular bisectors of the sides of the triangle. The perpendicular bisectors are to be plotted on the graph.

Coordinates A(1, 6), B(5, 4), C(5, -2)

__

a) Graph and label the triangle

b) Find the midpoint of each side of the triangle

c) Find the slope of each side of the triangle

d) Find the slope of each perpendicular bisector

e) Use the midpoint and the perpendicular slope to accurately draw each perpendicular bisector on the triangle

__

See the attached graph for shaded triangle ABC.

__

The midpoint (M) of a segment AB will be ...

  M = (A+B)/2

For example, the midpoint of segment AB is ...

  D = ((1, 6) +(5, 4))/2 = (1+5, 6+4)/2 = (6, 10)/2 = (3, 5)

This repetitive arithmetic is carried out in the spreadsheet shown in the second attachment. The midpoints are ...

  D(3, 5) is midpoint of AB

  E(5, 1) is midpoint of BC

  F(3, 2) is midpoint of CA

__

The slope of a segment is found using the slope formula (or by counting grid squares). That formula is ...

  m = (y2 -y1)/(x2 -x1)

For segment AB, this is ...

  mAB = (4 -6)/(5 -1) = -2/4 = -1/2

The other slopes are calculated similarly in the spreadsheet. When the denominator is zero (a vertical line), the slope is "undefined."

  mBC = undefined

  mCA = -2

__

The slope of the perpendicular line is the opposite reciprocal of the slope of the segment.

  m⟂AB = -1/(-1/2) = 2

  m⟂BC = 0 . . . . . a horizontal line has 0 slope

  m⟂CA = -1/-2 = 1/2

__

The perpendicular bisectors of each of the sides of the triangle are shown in the first attachment. As the lesson title indicates, their point of concurrency is G(1, 1), the circumcenter of the triangle.

Answer:

a = 2/5

Step-by-step explanation:

a + 1/10 = 5/10

Subtract 1/10 from both sides of the equation.

a + 1/10 = 5/10

-1/10 -1/10

a = 4/10

This answer is not incorrect but we usually need to simplify it if possible.

4/10 can be reduced to 2/5.

a = 2/5

Answer:

a=2/5

Step-by-step explanation:

To solve this, we first need to isolate the a so we can solve from there

First, we subtract 1/10. But whatever we do to one side we have to do to the other side. So when we subtract 1/10 from the left side we cancel it out and we subtract 1/10 from the right side so 5/10-1/10

So our equation becomes…

a=5/10-1/10

We can simplify this to…

a=4/10

4/10 is equal to 2/5

So that is our final answer

Now since we have nothing else to do that is our final answer

PLEASE AWARD BRAINLIEST I REALLY NEED TO LEVEL UP!

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{4} x-4\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so we're really looking for the equation of a line whose slope is 4 and passes through (-2 , 0)

[tex](\stackrel{x_1}{-2}~,~\stackrel{y_1}{0})\qquad \qquad \stackrel{slope}{m}\implies 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{4}(x-\stackrel{x_1}{(-2)}) \\\\\\ y=4(x+2)\implies y=4x+8[/tex]

Answer:

  638

Step-by-step explanation:

The total number of responses is the value of a geometric series with first term 70 and common ratio 1-10% = 0.90. That sum is given by the formula ...

  Sn = a1·(1 -r^n)/(1 -r)

where r is the common ratio, n is the number of terms, and a1 is the first term.

The sum of n=23 terms of the series with a1=70 and r=0.9 is ...

  S23 = 70·(1 -0.9^23)/(1 -0.9) = 700(1 -0.9^23) ≈ 638

The model predicts 638 total responses over the first 23 days.

wag Po lagi umasa sa brainl.

Answer: See below

Step-by-step explanation:

30% * 50

= 30/100 * 50

= 15

Therefore, 30% of the integers between 1 and 50 are in the range 1 to 15

So the random integer generated is in this range, that is, less than or equal to 15, then the weather must be simulated to be rainy.

This would mean that the chance of rain on each day is 30% (if the computer generates the random number consistently)

Answer:

Total percentage is always 100% so if its 12% for her to slip the remainder is 100-12= 88.

88% she doesn't slip.

Using Percentage, the odds against jessie slips on the ice is 88%.

A percentage is a "number or ratio that can be expressed as a fraction of 100".

According to the question,

The probability of jessie slip on the ice is 12% and the percentage is always taken as 100%.

In order to find the odds against jessie slips on the ice only if difference from 100% to 12%.

100 - 12 = 88.

Hence, the odds against jessie slips on the ice is 88 percentage.

Expand brackets:

⇒ 5 + 4x - 6 ≥ 3x + 4

Combine like terms:
