Hi there!
Let r be the number of matches that Rebecca's team won.
We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.
Using this given information, we can create the following equation.

If you wish to solve this, we can subtract both sides by 9 to get the following value for r.

Have an awesome day! :)

-5x + x + 9 = -4x + 12
-4x+9= -4x+12
move +9 to the other side
sign changes from +9 to -9
-4x+9-9= -4x+12-9
-4x= -4x+3
move -4x to the left side
sign changes from -4x to +4x
-4x+4x= -4x+4x+3
0= 0+3
0= 3
Answer: no solution
Answer:
(10,0)
Step-by-step explanation:
4x - 5y = 40
To find the x intercept, set y =0 and solve for x
4x - 0 = 40
4x= 40
Divide by 4
4x/4 = 40/4
x = 10
The x intercept is 10

Answer:
henc X = 30°
Step-by-step explanation:
here is the proof
when X=30° then
sin2x = sin2×30
=sin 60°
= √3/2
or else,
putting value of X = 30° then
sin2x= 2sinxcosx
= 2×sin30°×cos30°
=2×1/2×√3/2
= 2√3/4
= √3/2
hence proved sin2x= √3/2.
