3p - 2(p-4) = 7p + 6
Serggg [28]

For this case we must find the value of the variable "p" of the following equation:

3p-2 (p-4) = 7p + 6

We apply distributive property on the left side of the equation taking into account that +*-=-  and - * - = +:

3p-2p + 8 = 7p + 6

We add similar terms:

p + 8 = 7p + 6

We subtract 7p  from both sides of the equation:

p-7p + 8 = 6\\-6p + 8 = 6

We subtract 8 from both sides of the equation:

-6p = 6-8\\-6p = -2

We divide by -6 on both sides of the equation:

p = \frac {-2} {- 6}\\p = \frac {1} {3}

Answer:

p = \frac {1} {3}

In Bobby’s school, math grades for the year are calculated from assignments, tests and a final exam. Assignments count 30%, test
jarptica [38.1K]

Answer:

A) Bobby's overall grade is 70.4%

Step-by-step explanation:

To solve this problem we must calculate the percentages each grade represents from the overall grade. Therefore:

assignment = 85*30% = 85*30/100 = 25.5%

tests = 72*20% = 72*20/100 = 14.4%

exam = 61*50% = 61*50/100 = 30.5%

total = assignment + tests  + exam

total = 25.5 + 14.4 + 30.5 = 70.4

Bobby's overall grade is 70.4%. Therefore the correct answer is A).
