Mr. Patrick teaches math to 1515 students. He was grading tests and found that when he graded everyone's test except Payton's, t

julsineya [31]

Given:
15 students
average grade: 80 for 14 students
average grade: 81 for 15 students

80 * 14 = 1120
81 * 15 = 1215

1215 - 1120 = 95

Payton's score on the test is 95.

2x2 - 3x - 2 = x + 4.check all of the solutions to this equation.-137(–1, 3)(3, 7)

g100num [7]

Answer:

The correct option is: (-1, 3)

Step-by-step explanation:

The given equation is: $2x^2-3x-2=x+4$

First we will move all terms to the left side and make the right side as zero. So......

$2x^2-3x-2-x-4=0\\ \\ 2x^2-4x-6=0$

Now, we can divide both sides of this equation by 2. So, we will get......

$\frac{2x^2-4x-6}{2}=\frac{0}{2}\\ \\ x^2-2x-3=0$

Factoring out the left side..........

$x^2-2x-3 =0\\ \\ (x-3)(x+1)=0$

Now, using zero-product property, we will get.........

$x-3=0\\x=3\\ \\and\\ \\ x+1=0\\ x=-1$

So, the solutions to the equation will be: (-1, 3)

Tammy runs 7 miles in 80 mins. At the same rate, how many miles would she run in 64 mins?

denis23 [38]

In order to do this problem, you would have to set up rate of change equation. Distance/time (d/t)
7 mi/80 mins = x mi/64 mins
Solve this equation by solving for x.
80x = 7(64)
X = 5.6
So Tammy ran 5.6 miles.
