Answer:
A. -6r + 6
Mathpapa is a great app for algebra questions btw. Its helped me a lot
<span>You can solve this problem using this equation: 34x + 14 = 30x + 22.
The x stands for how many points each multiple choice question is worth. 34x is the number of multiple choice questions Francine got correct multiplied by the currently unknown number each point is worth, while 14 represents the 14 points that Francine was given for her essay. 30x is the number of multiple choice questions Cheryl got correct multiplied by the currently unknown number each point is worth, while 22 represents the 22 points that Cheryl was given for her essay.
To solve, we can subtract 30x from 34x on the left side of the equation, and subtract 14 from 22 on the right side of the equation. That leaves, 4x = 8. Next step would be dividing 4 from each side which gives us x = 2. In order for Francine and Cheryl to receive the same test score, each multiple choice questions would have to be worth 2 points.</span>
JMK’s angle is part of the right angle of JMN. The measurements there is 28°. A right angle is 90° so subtract 90 and 28 to get your angle measurement of JMK.
A small hint for the STR one is the fact that the straight lines are 180°. So Look at the line RTS. RTS is 180° by adding both the measurement of STR and STP. Simply subtract 180° with 118 to get STR.

Answer:64 students
Step-by-step explanation:
using the empirical rule, we know that 34% of a normal distribunion is below the mean but above 1 standard deviation. This means that 16% of the students enter before 9:55. Take 16% of 400 and you get the amount of students in before 9:55
