Answer: 3
Explanation:
She wants to get 70%, so we need to solve
x/20 = 70/100
Doing so gets us
100x = 20*70
100x = 1400
x = 1400/100
x = 14
She needs to have 14 questions correct, out of 20, to get a score of 70%
14/20 = 0.70 = 70%
She needs to get 14-11 = 3 more correct questions.
46,500 if I am not wrong.
Hope this helps!

The answer is b.
|2| = 2
|-4| = 4
4 is greater than 2.
Answer:
y = -20x + 100
Step-by-step explanation:
As per your requirement For Part B, the solution is
The equation in slope-intercept form to model the relations is below:-
To reach 2 points on the graph the line passes through
lets use p1(0, 100), p2(1, 80)
now we will compute the slope:


= -20
and now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 100 = -20(x - 0)
y = -20x + 100
