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.
Answer:
One solution
Step-by-step explanation:
To start, let's simplify the equations to slope-intercept form
y - 1/4x = =1
+1/4x +1/4x
y = 1/4x - 1
y - 2 = 4x
+2 +2
y = 4x + 2
As you can see, the equations do not have anything in common worth mentioning. The slopes are different and the y-intercepts are different, so there must be only one solution.
