Answer:
2 1/2
Step-by-step explanation:
Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.
4 3/4
4 * 4 + 3 = 19
19/4
2 1/4
2 * 4 + 1 = 9
9/4
Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.
19/4 - 9/4 = 10/4
Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:
4 * 2 = 8
10 - 8 = 2
2 1/2
Answer:
Jeffery has 1,028 apple trees in his orchard
Step-by-step explanation:
In this question, we are asked to calculate the number of apple trees owned by Jeffery.
Firstly, we identify that Jeffery has an orchard containing 2 parcels of land.
In the first parcel of land, we have 28 rows of trees with 32 trees per row. The total number of trees here would be 28 * 32 = 896 trees
In the second parcel, there are 132 trees.
To get the total number of trees, we simply add the number of trees in the first parcel to the number of trees in the second.
Mathematically, that is 132 + 896 = 1,028 trees
<span>When order does not matter you use what is called n choose k formula
n!/(k!(n-k)!) where n is the number of things to choose from and k is the number of choices made, in this case:
20!/(4!(20-4)!)=4845</span>

Answer:
y=4x-1
Step-by-step explanation:
Slope-intercept form is written in y=mx+b
*m=slope
*b=y-intercept
From what I see,
the line hits the points (0,-1) and (1,3)
Slope is the rise (change in the y-coordinate) of the line divided by the run (change in the x-coordinate).
4÷1=4
Slope=4
y=4x+b now
The y-intercept is the value of y when the line meets the y-axis
It seems to meet at (0,-1)
So we end up with...
y=4x-1 as our equation
