Hi, Siyasi2 ! Let x = the number of hot dogs, y = the number of chips, and z = the number of drinks. Then we know:
5x + 4y + 5z = 15.75
x = y + 0.75
z = 2x - 1
Let's substitute the 3rd equation into the first one.
5x + 4y + 5(2x - 1) = 15.75
5x + 4y+ 10x - 5 = 15.75
15x + 4y = 20.75
Now, let's re-write the 2nd equation as x - y = 0.75
We now have a system of two equations with two unknowns.
15x + 4y = 20.75
x - y = 0.75
To solve this, we can multiply the bottom equation by 4 and add.
15x + 4y = 20.75
+ 4(x - y = 0.75)
19x = 23.75
or x = 1.25
If x = 1.25, then using the one of the equations above, we can solve for y.
x - y = 1.25 - y = 0.75
.50 = y
Since z = 2x - 1, then z = 2(1.25) - 1 = 2.5 - 1 = 1.50
So, a hot dog is $1.25, chips are 50 cents, and a soft drink is $1.50. Please let me know if you have any questions.
Answer:
8.7
Step-by-step explanation:
To find the mean first you have to add up all the weight of the cats which is:
After, you have to divide the total weight by the number of cats there are
which is: 
Since, this is a really long number you would normally round the number to the nearest tenth which is 8.7

C=5
F=25
D=2
L=50
R=3
I=80
G=48
N=40
A=1
T=10
S=12
H=7
O=11
Now,
1. 10 7 15 = THE
2. 3 11 48 300 15 12 = ROGUES
3. 11 3 1 40 48 15 = ORANGE
4. 12 7 11 15 = SHOE
5. 25 15 50 50 = FELL
6. 11 25 25 = OFF
7. 2 300 3 80 40 48 = DURING
8. 1 = A
9. 5 7 1 12 15 = CHASE
That's your answer of first page
