7 0

Answer:

x = 4

Step-by-step explanation:

as it is parallelogram opposite sides are equal

so14x -7= 10x-9

14x-7+9=10x

14x -16 = 10x

14x -10x = 16

4x =16

x = 16/4

x = 4

also u can put x = 4 in both expressions and u will get answer of both 49

Answer:

a) 115°

b) 140°

c) 75°

d) 255°

Step-by-step explanation:

a) another line parallel to AB through E will split x into two sectors.

Parallel lines intersected by a third line makes opposite internal angles of equal value. Supplemental angles add to 180°

x = (180 - 120) + (180 - 125) = 115°

b) double application of parallel lines intersected by a third line making corresponding angles identical.

c)  more of the same

d) more of the same

Determine the intercepts of the line.
sergey [27]

Answer:

  y-intercept: (0, 5/2)

  x-intercept: (5/3, 0)

Step-by-step explanation:

The y-intercept is found by setting x=0 and dividing by the coefficient of y.

  0 +2y = 5

  y = 5/2

The x-intercept is found by setting y=0 and dividing by the coefficient of x.

  3x +0 = 5

  x = 5/3

The intercepts are ...

  y-intercept: (0, 5/2)

  x-intercept: (5/3, 0)

Help me on the first question pls
Margaret [11]
To do the first question, simplify the equation, putting like terms together, by adding and subtracting to do this.

Then looking at the equation that you solved for, look and see if there are any other equations that are related in some way to the original solved equation.

Pay close attention to the positive and negative signs.

Estimate what is 130% of 20. Show work please! I need the right answer!
aksik [14]
26 would 130% of 26%. 

20 would be 100% of itself leading us to X being 130%. 
That brings us to two equations of 20=100% and x=130%
20/x=100%/130%

20/x=100/130
(20/x)*x=(100/130)*x
20=0.769230769231*x
26/0.769230769231=x
26=x therefor x=26
