Answer:
q = 2/3p - 3
Step by step:
2q+2p = 1+5q
2q - 5q = -2p + 1
-3q = -2p + 1
q = 2/3p - 3
Answer:
To get the slope, we can first mark out any 2 points of the line.
In this case, I will use the point (-2, 0) which will be (x1, y1) and (0, -2) which I will call (x2, y2).
To get the slope, you need to do 
Substitute these values in:
The slope is -1.
Answer:
Section A: Sally drives from her house to her friend's house.
Section B: Sally stops to visit her friend.
Section C: Sally drives from her friend's house to the post office to drop off a card.
Section D: Sally drives back to her house.
Step-by-step explanation:
As you can see in the graph, the point (0,0) is the location of Sally's house. In that point the distance is 0 and the time is 0.
In Section A she drives 3 miles in 6 minutes from her house to her friend's house.
In Section B, the distance does not change, this means that Sally stopped at her friend's house for 4 minutes.
In Section C she drives (for 4 minutes) 1 mile from her friend's house to some place (In this case the post office).
In Section D she comes back to 0 distance, then, she drives back to home.
There are 35 different sections on the spinner.
To solve this, we can write a proportion. We put 8 over the number of sections and set it equal to 23 over 100 for 23%.
8 / x = 23 / 100
Cross multiply and divide and you will get an answer of about 35.
Answer:
The regular costs 11 dollars each while the deluxe cost 23 each.
Step-by-step explanation:
You need to setup two equations.I used two variable for the prices of the types of pizzas because they are unknown.I used x for the cost of regular and y for the cost of deluxe.The equation I did are 10x+y=133 and 7x+9y=284.You need to solve one equation only.I solved the first one.
