Explanation:
First, switch sides of an equation.
Then, you subtract by the 80 from both sides of an equation.
And finally, simplify and subtract the numbers.
Hope this helps!
Thank you!
Have a great day!

Answer:
Step-by-step explanation:
There's a lot of information missing here, and the given list of choices is basically incomprehensible.
Suppose J (a, b) and K (c, d) are two points in the plane. We can trace out the line segment JK joining these points with the function
r(t) = (1 - t) (a, b) + t (c, d)
where 0 ≤ t ≤ 1.
Let P be the point that divides JK into line segments JP and PK having a length ratio of 2:5. Then JP is the point 2/7 of the way along JK, so that the coordinates of P are
P = r(2/7) = 5/7 (a, b) + 2/7 (c, d) = ((5a + 2c)/7, (5b + 2d)/7)
and in particular the x-coordinate of P is (5a + 2c)/7.
Answer:
<u>3 batches of biscuits.</u>
Step-by-step explanation:
For one batch of biscuits, Mito uses 1/4 cup of flour to coat the countertop and the rolling pin.He also uses 2 1/2 cups of flour for each batch of biscuits he bakes
When he uses 7 3/4 cups of flour
Let the number of batches = x
convert the given data to decimal:
2 1/2 = 2.5 and 1/4 = 0.25 and 7 3/4 = 7.75
So, the equation representing the problem is:
2.5 x + 0.25 = 7.75
Solve for x
2.5x = 7.75 - 0.25 = 7.5
x=7.5/2.5 = 75/25 = 3
<u>So, the number of batches of biscuits = 3 batches.</u>
