Answer:

2m+40=100, 30 movies

Step-by-step explanation:

1 movie = 2 points

1 pass= 100 points

curently have 40 points so

100points = 40points +2points *m

solve for m:

2m+40 =100 subtract 40 from both sides

2m = 100-40

2m=60 divide both sides by 2

m=60/2

m=30

Answer:

$\frac{4\sqrt{6}-\sqrt{15}}{27}$

Step-by-step explanation:

$\frac{\sqrt{6} }{8+\sqrt{10} } \\\\\mathrm{Multiply\:by\:the\:conjugate}\:\frac{8-\sqrt{10}}{8-\sqrt{10}}\\=\frac{\sqrt{6}\left(8-\sqrt{10}\right)}{\left(8+\sqrt{10}\right)\left(8-\sqrt{10}\right)}\\\\\sqrt{6}\left(8-\sqrt{10}\right)=8\sqrt{6}-2\sqrt{15}\\\left(8+\sqrt{10}\right)\left(8-\sqrt{10}\right)=54\\\\=\frac{8\sqrt{6}-2\sqrt{15}}{54}\\\\\mathrm{Factor}\:8\sqrt{6}-2\sqrt{15}:\quad 2\left(4\sqrt{6}-\sqrt{15}\right)\\\\=\frac{2\left(4\sqrt{6}-\sqrt{15}\right)}{54}\\$

$\mathrm{Cancel\:the\:common\:factor:}\:2\\\\=\frac{4\sqrt{6}-\sqrt{15}}{27}$

Branliest offered <br> Solve equation <br> 6x+3x+8=35<br> 12w-5-3w=40

aniked [119]

6x+3x+8=35
Step 1: Simplify both sides of the equation.
6x+3x+8=35
(6x+3x)+(8)=35(Combine Like Terms)
9x+8=35
9x+8=35
Step 2: Subtract 8 from both sides.
9x+8−8=35−8
9x=27
Step 3: Divide both sides by 9.
9x
9
=
27
9
x=3
Answer:
x=3
12w−5−3w=40
Step 1: Simplify both sides of the equation.
12w−5−3w=40
12w+−5+−3w=40
(12w+−3w)+(−5)=40(Combine Like Terms)
9w+−5=40
9w−5=40
Step 2: Add 5 to both sides.
9w−5+5=40+5
9w=45
Step 3: Divide both sides by 9.
9w
9
=
45
