Answer: Mari=16, Carlos=21, Amanda=63

Mari: M
Carlos: M + 5
Amanda: 3(M + 5)
Total: 100
Mari + Carlos + Amanda = Total
M + M + 5 + 3(M + 5) = 100
2M + 5 + 3M + 15 = 100
5M + 20 = 100
5M = 80
M = 16
Carlos (C): M + 5 = (16) + 5 = 21
Amanda (A): 3(M + 5) = 3(16 + 5) = 3(21) = 63
Answer: Mari=16, Carlos=21, Amanda=63

hope this helps!

a segment has endpoints at (1, -2) The midpoint is at (-4, -2). What are the cooordinates of the other endpoint?
vfiekz [6]

Answer:

coordinate of the other endpoint is (-9,-2)

Step-by-step explanation:

Given that a segment has endpoints at (1, -2). The midpoint is at (-4, -2).

Now we need to find about what are the coordinates of the other endpoint.

let the coordinates of other end points are (x,y)

Then mid point of (1,-2) and (x,y) is given by mid point formula:

\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)

\left(\frac{x+1}{2},\frac{y-2}{2}\right)=(-4,-2)

\Rightarrow \frac{x+1}{2}=-4, \frac{y-2}{2}=-2

\Rightarrow x+1=-8, y-2=-4

\Rightarrow x=-9, y=-2

hence coordinate of the other endpoint is (-9,-2)

Given: — <br> Xw Is an altitude <br> M Prove: x=12
blsea [12.9K]

Answer:

See explanation

Step-by-step explanation:

<u>Given:</u> XW is an altitude

m∠XWY=8x-6

<u>Prove:</u> x=2

<u>Solution:</u>

      Statement                                 Reason

1. XW is an altitude                         Given

2. m∠XWY = 90°                            Definition of altitude

3. m∠XWY = 8x - 6                         Given

4. 8x - 6 = 90                                  Substitution property

5. 8x - 6 + 6 = 90 + 6                     Addition property of equality

   8x = 90

6. x = 12                                          Division property of equality

Write an equation in point-slope form of the line that passes through the point (−3,6) and has a slope of 5.
strojnjashka [21]

Answer:

Below in bold.

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1)

where m = the slope of the line and (x1, y1) is a point on the line.

Here m = 5, x1 = -3 and y1 = 6.

So we have:

y - 6 = 5( x - (-3))

y - 6 = 5(x + 3)   (Answer)
