A*4=e b\4=e c+4=e d-4=e A+b+c+d=100
ratelena [41]
I believed you are looking for the value of e. The value of e is 16 below is the solution:

A×4 = E, so A=E/4
B/4 = E, so B=4E
C+4 = E, so C=E=4
D-4 = E, so D=E+4
and
A+B+C+D=100.

Substitute values of A, B, C and D in the equation, we get,
(E/4) + 4E + E-4 + E+4 = 100
(E/4) + 4E + 2E = 100
(E/4) + 6E = 100
(E+24E)/4 = 100
E+24E = 100×4
25E = 400
E = 400/25

Ingnore question 17 but i need help 30 POINTS!!!
algol [13]
Not sure why they put the x bit

ok so know this:
AGE=HGB=CHG=FHD
and
AGH=EGB=CHF=GHD
and
AGE+AGH=180


11.
AGE=FHD=30

12.
AGH=CHF=150

13.
CHF=BGE=110

14.
CHG+HGA=180
CHG+120=180
CHG=60

15.
BHG=3x=AGE=CHG=FHD
not sure, but if we did use the fact that BGH+DHG=180 and BGH=3x and DHG=2x+50 then BHG=78 degrees

16.
GHD=2x+50=CHF=EGB=AGH, if we use facts above then GHD=102 degrees

You are dealt one card from 52 card deck. Find the possibility that you are dealt a heart or a picture card
PIT_PIT [208]

Answer:

<h2>11/26</h2>

Step-by-step explanation:

Since we have 13 heart card then

p(heart) = 13/52

Since we have 12 picture card then

p(picture) = 12/52

Since we have 3 heart and picture (at the same time) card then

p(heart∩picture) = 3/52

finally,

the possibility that you are dealt a heart or a picture card = p(heart or picture)

p(heart or picture) = 13/52 + 12/52 - 3/52 = 22/52

Solve by elimination:<br> 4x+9y=28<br> -4x-y=-28
nikdorinn [45]

Step-by-step explanation:

4x+9y=28

-4x-y=-28

8y=0

divide both side by 8

y=0

solve for X in equation 1

4(X)-9(0)=28

4x-0=28

4x =28

divide both side by 4

4x/4=28/4

X= 7

y=0,x=7

Solve for p. 20p + -5p – -17 = -13
STatiana [176]
20p + -5p - -17 = -13 

20p + -5p - -17 = -13:p  |Solve \  for \ p| 

20p-5p+17=-13 

&#10;15p+17=-13&#10; &#10; 

&#10;15p=-13-17&#10; &#10;  |Subtract \ 17 \ from \ both \ sides| 

&#10;15p=-30&#10; &#10; 

&#10;15p/15=-30/15&#10; &#10;  |Divide  \ both \ sides \ by \ 15| 

&#10;p=-2&#10; &#10;
