At the city museum, child admission is $5.60 and adult admission is $9.60. On Thursday, 153 tickets were sold for a total sales

JulsSmile [24]

Answer:

95 child tickets

Step-by-step explanation:

a+c =153 c=( 153-a) you need to plug this for c

9.6a + 5.6(153-a) = 1088.8

9.6a + 856.8 - 5.6a = 1088.8

4a +856.8 = 1088.8

subtract 856.8 on both sides

4a = 232

a=58 (58 adults)

153 - 58 = 95 (95 children)

95*$ 5.6 = $532

85 *$ 9.6 =$ 556.8

$532 + $556.8 =$ 1088.8

Alice cycles to Carla's house at 12 mph and returns by car at 36 mph. If the round trip takes 1 hour, how far away from Carla do

Eduardwww [97]

Answer:

Alice lives <u>9 miles</u> far away from Carla.

Step-by-step explanation:

Given:

Alice cycles to Carla's house at 12 mph and returns by car at 36 mph.

If the round trip takes 1 hour.

Now, to find the distance from Carla to Alice house.

So, let the distance between the houses of Carla and Alice be $x$ .

Now, we solve by using the formula:

Distance/speed = time

Alice cycles to Carla house = $\frac{x}{12}$

And return by car = $\frac{x}{36}$

Time taken for round trip = 1 hour.

Adding both the distance to get the value of x:

$\frac{x}{12}+\frac{x}{36}=1$

$=\frac{3x+x}{36}=1$

$=\frac{4x}{36}=1$

<em>Dividing both sides by 4 we get:</em>

$x=9$

Therefore, Alice lives 9 miles far away from Carla.

1. 7x + 3 - 2x....x = 8
7(8) + 3 - 2(8) = 56 + 3 - 16 = 43

4. 7 - (-2y) + y - 9....y = 6
7 - (-2(6) + 6 - 9 = 7 + 12 + 6 - 9 = 16

7. -x + 8 + 7x - (-1).....x = -10
-(-10) + 8 + 7(-10) + 1 = 10 + 8 - 70 + 1 = -51

10. 4x + 2y - x - 8....x = 1, y = 5
4(1) + 2(5) - 1 - 8 = 4 + 10 - 9 = 5

13. 2x + 5y - 3x + (-8y)....x = -9, y = 9
2(-9) + 5(9) - 3(-9) - 8(9) = -18 + 45 + 27 - 72 = -18
