Answer : 0.125 flyers per poster
Step-by-step explanation:
7/56 = 0.125
Answer:
2
Step-by-step explanation:
First plug in all the numbers into the variables.
3(2^2) - (18 - 4(2))/ 3^2 - 8
This is what your equation should look like after you plugged in 2 for the a and 3 for the b. Then you solve them individually; starting with 3(2^2). 2^2 is 4 and 3 × 4 is 12. So now the equation should look like this:
12 - (18 - 4(2))/ 3^2 - 8
Next, we can solve for (18 - 4(2)). So -4 × 2 is -8, and then you have (18 - 8). That answer would be 10. You should have 12 - 10 on top now, and the answer to that is just 2. Now your equation should look like this:
2/ 3^2 - 8
Now onto 3^2 - 8. 3^2 is 9 because that would just be 3 × 3. Now you have 9 - 8, which is 1. So now you should be left with:
2/1
And that's your final answer.
Answer:
a) 4 people ordered streak dinner
b) 3 people ordered chicken dinner
Step-by-step explanation:
Let the number of people that ordered steak dinner be x
and the number of people that ordered chicken dinner be y
From the question,
There are 7 people in your family
Hence, we can write that
x + y = 7 ...... (1)
Also from the question
Some order the chicken dinner for $13 and some order the steak dinner for $18 and the total bill was $111.
We can then write that
13y + 18x = 111 ...... (2)
From equation (1)
x + y = 7
Then,
x = 7 - y ...... (3)
Put this into equation (2)
13y + 18x = 111
13y + 18(7 - y) = 111
13y + 126 - 18y = 111
-5y = -15
5y = 15
y = 15 / 5
y = 3
Put the value of y into equation (3) to get x
x = 7 - y
Then
x = 7 - 3
x = 4
Hence, 4 people ordered streak dinner
and 3 people ordered chicken dinner
a) 4 people ordered streak dinner
b) 3 people ordered chicken dinner
Just set up the equation and solve for x, that is the time.
40(0.9-x) = 5x
36 = 45x
x = 36/45
x = 0.8
It took Talia 0.8 hours (48 minutes) to walk home.
C. 7.5
3/4 = .75
7.5/10 = .75
