Answer:
B(-5,5).
Step-by-step explanation:
It is given that midpoint of AB is M (-6,1).
Coordinates of A are (-7,-3 ).
We need to find the coordinates of point B.
Let coordinates of point B are (a,b).
Midpoint of AB is
On comparing both sides, we get
Therefore, the coordinates of B are (-5,5).
When you are told to estimate, you should be able to do the problem in your head.
8 7/12 is close to 8 1/2
4 7/8 is very nearly 5
4/10 is very nearly 1/2
8 1/2 - 5 - 1/2 First of all you can take the 1/2 away from 8 1/2
8 1/2 - 1/2 = 8
Now take away the 5
8 - 5 = 3
So the answer is very nearly
3 <<<<< answer.
Just for fun, I'll get the exact answer. Don't hand this one in. It is 3 37/120
You learn to estimate because you are trying to guess whether or not you've entered everything correctly into your calculator. When writing a test, this is a very handy skill to have developed.
The equation in term of p that models the above experience is:
2p + 10 = 0.8p + 20.
<h3>
What is an equation?</h3>
Any statement that models or captures the factors of a problem where in an equal sign is present to equate two of the factors or expressions therein is called an equation.
<h3>How do we form the above equation?</h3>
- Everyday pizza production is equal to p.
- Brick oven use fees are $10 per day.
- Ingredients for brick oven pizza cost $2 per pizza.
- $20 a day is the cost of using an electric oven.
- Pizzas baked in an electric oven cost $0.8 per pizza in ingredients.
- If an electric oven is used, the total cost of making a pizza falls by $1, including the cost of the ingredients.
Total cost of baking p pizzas with brick oven = A = p(cost of one pizza) + cost of baking = p(2) + 10 (in dollars).
Total cost of baking p pizzas with electric oven = B = p(cost of one pizza) + cost of baking = p(0.8) + 20 (in dollars).
B = A - 1 (as using electric oven saves $1 per day, as given)
Thus, we get:
2p + 10 = 0.8p + 20

Answer:
Step-by-step explanation:
We have to rewrite the below as simplified fraction.
Solution:
Let 
which means 
Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.
To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.
So, we can rewrite 
as:
......(1)
Now, let us multiply the above with 10.
....... (2)
Now, let us subtract (1) from (2):
So, in simplified fractions:
