2x + 5y = 10
Change to y = mx + b
subtract 2x from both sides
5y = -2x + 10
divide both sides by 5
y = -2/5x + 2
slope = -2/5
LETTER B
12, 20, 16, 10, 17, 9, 23, 13
1. add them all up
=120
divide by the number of numbers
120/8
=15
15 is the MAD
I think the answer is -7x(-7)x(-7)
Using proportions, it is found that the amount of the novel she would have read is:
D. 14/15.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
She has finished 5/6 of the novel, and will have read more 1/10 in the next two days, hence the total amount read is given by:

Hence option D is correct.

If 24 students went on a field trip, and 24 students represented eight tenths of the class, then

.
First, multiply by 10 on both sides.
240 = 8x
Divide by 8 on both sides.
x = 30.
The class has 30 students in all.
This is, however, only the equation way to solve.
