1 = x(2) - 2x - 3
1 = 2x + -2x + - 3
1 = (2x + -2x) + (-3)
1 = -3
1 - 1 = -3 -1
0 = -4

light travels 3000000 scs if earth is 150 million km away from sun how many minutes it will take the light to come from sun to e
sweet-ann [11.9K]
  • Speed of light=3×10^8m/s=3×10^5km/s
  • Distance=150million km=150×10^6km

Now

\\ \rm\longmapsto Speed=\dfrac{Distance}{Time}

\\ \rm\longmapsto Time=\dfrac{Distance}{Speed}

\\ \rm\longmapsto Time=\dfrac{150\times 10^6}{3\times 10^5}

\\ \rm\longmapsto Time=50\times 10^1

\\ \rm\longmapsto Time=500s

\\ \rm\longmapsto Time=8.33min

  • Can be written as 8min 20s.

At a movie theater, admission tickets cost $10 for adults and $8 for children. On Saturday, Anne Teak collected a total of $1276
kow [346]

Answer:

Part a) variable x (the number of adult tickets sold) and variable y (the number of child tickets sold)

Part b) 10x+8y=1,276

Part c) The number of adult tickets sold was 86

Step-by-step explanation:

Part a) Name a variable for the number of adult tickets sold and name a variable for the number of child tickets sold

Let

x -----> the number of adult tickets sold

y -----> the number of child tickets sold

Part b) Write an equation in two variables to model the problem

we know that

10x+8y=1,276 -----> equation A

y=52  -----> equation B

substitute equation B in equation A and solve for x

10x+8(52)=1,276

10x+416=1,276

Part c) Using your equation in Part B, solve the problem and answer the question "how many adult tickets did Anne sell?" i

we have

10x+416=1,276

Solve for x

Subtract 416 both sides

10x=1,276-416

10x=860

x=86

therefore

The number of adult tickets sold was 86
