Answer:
Slope = 4
Step-by-step explanation:
The x-axis values to represent the number of correct answers.
The y-axis values to represent the number of points earned.
The points on the graph are: (17,68) , (20,80) and (24,96)
The slope(m) of the graph = change in y ÷ change in x
i.e
=
= 4
The equation of the straight line graph is;
y=4x
In order to find the unit rate of acres per day, or in other words, how many acres can they plant in one day, you must divide 5/8, the number of acres planted, by 4/5, the number of days it took to plant. When you divide the two fractions, first set up an expression:
5/8<span>÷4/5
Then, to make things simpler, turn the division expression into a multiplication statement so that you have 5/8*5/4. Then multiply straight across and you get your answer as 25/32. This means that the workers can plant 25/32 acres per day.</span>

Step-by-step explanation:
Hi there!
is an irrational number.
Now, what is an irrational number? An irrational number is a number that goes on for ever.
Examples: 
is a surd (an irrational square root)
If we multiply 2 times
, we will get an irrational number.

Using a system of equations, it is found that Susan had 44 quarters, 11 dimes and 27 nickels.
--------------------------------
We are going to use:
- x as the number of quarters.
- y as the number of dimes.
- z as the number of nickels.
A <em>quarter </em>is worth $0.25. A <em>dime </em>is worth $0.1, and a <em>nickel </em>is worth $0.05. Total of $13.45, then:

4 times as many <u>quarters as dimes</u>, thus:

16 less <u>dimes than nickels</u>, thus:

Replacing in the first equation, we find x:





Now, with x, we find y and z:


Susan had 44 quarters, 11 dimes and 27 nickels.
