Answer:
Option D is correct
Step-by-step explanation:
-4(3x/2 - 1/2) = -15
<=>
-4*3x/2 + (-4)*(-1/2) = -15
<=>
-6x + 2 = -15
It would end up being .63¢
Answer: y= (x+2)² −

Step-by-step explanation:
The way I got this answer is by completing the square. The first step though, when looking at this equation, is to see if we can factor it. The way to check is to look at the coefficient for x² which is 1, and the constant, in this case -1. If we multiply those together, we get −. Now we look at the middle term, 4x. We need to find any numbers that multiply to equal − 1x² and add to 4x. There aren't any, which means it is not factorable.

Answer:
Step-by-step explanation: So there are 148 students total and we know the fifth graders filled up 12 rows and since each row has a number of 8 seats we should multiply 8 times 12, which is equal to 96. Now in order to find the number of rows needed for the fourth graders we should first, subtract 178 minus 96; that is equal to 82. Next, we should divide 82 by the number of seats in each row since what we are trying to find id the number of rows needed for the fourth graders. So, we should divide 82 by 8 which is equal to 10. 25.
The number of rows needed is 11 since all students need to have a seat; the answer cannot be 10 because that means a few students would not have a seat.
