1 = 1.5x -1
+1 +1
2 = 1.5x
/1.5 /1.5
4/3 = x

y = 1.5 ( 4/3 ) -1
y = 1

solution:
x = 4/3
y = 1

exis [7]

Answer:

$c = 11$

Step-by-step explanation:

Given

$Cars\ Sold:-: 8; 9; 12; c$

Required

What value of c makes the mean = 10

Mean is calculated as

$Mean = \frac{\sum x}{n}$

In this case;

Mean = 10 and n = 4;

So, we have:

$10 = \frac{8+ 9 + 12 + c}{4}$

$10 = \frac{29+ c}{4}$

Multiply both sides by 4

$10 * 4 = 29 + c$

$40 = 29 + c$

Solve for c

$c = 40 - 29$

$c = 11$

6 children and 2 adults are going to the circus, children tickets are on sale, half the price of adult tickets totaling $54. How

inna [77]

Answer:

Price of 1 child ticket is $5.4

Price of 1 adult ticket is $10.8

Step-by-step explanation:

Given:-

6 children and 2 adults are going for circus.

Children ticket is half the price of adult ticket.

Total ticketing cost =$54

To find:-

Cost of 1 child ticket=?

Cost of 1 Adult ticket=?

Solution:-

Let price of 1 child ticket be x and price of 1 adult ticket be y,

therefore from the given data we get 2 equations,

$6x+2y=54$ -----------------------------------(1)

$x=\frac{1}{2} y$ --------------------------------(2)

Now, substituting the value of x from equation 2 in equation 1,

$6x+2y=54$

$6(\frac{1}{2} y)+2y=54$

$\frac{6}{2}y+2y=54$

$3y+2y=54$

$5y=54$

$\therefore y=\frac{54}{5}$

$\therefore y =10.8$ ------------------------(3)

Now, substituting the value of y from equation 3 in equation 2,

$x=\frac{1}{2} y$

$\therefore x=\frac{1}{2} \times 10.8$ ------------(from equation 3)

$\therefore x=\frac{10.8}{2}$

$\therefore x=5.4$ ----------------------(4)

As, x is price of 1 child ticket and y is price of 1 adult ticket,

Therefore price of 1 child ticket is $5.4 and price of 1 adult ticket is $10.8

2(4a - 4b) + 4(3a + 2b)<br><br>plz solve this!!!

ivann1987 [24]

Answer:

2(4a - 4b) + 4(3a + 2b) = 20a

Step-by-step explanation:

2(4a - 4b) + 4(3a + 2b)

8a - 8b + 12a + 8b

8a + 12b - 8b + 8b

20a+ 0 = 20a

Thus, 2(4a - 4b) + 4(3a + 2b) = 20a
