Answer:
The decline in the performance of students of grade 12 has been concerning. There should be workshop for their improvement in learning. The students can have a chance to attend the workshop which will help them enhance their skills of reinforcement and skill of explaining and probing. The students will be able to polish their skills during different sessions of the workshop. The skill of reinforcement will add confidence to the students that they have ability to prove themselves.
Answer:
People use their card for a purchase they can’t afford or want to defer payment, and then they make only the minimum payment that month. Soon, they are in the habit of using their card to purchase things beyond their budget. Since they are making only the minimum monthly payment, it won’t seem to matter much if their credit card balance gets a bit larger. This is a quick illustration to show how their “small balance” of just a few thousand dollars can really mean paying more than double that amount over the years because of interest. Also, when they are trapped in this mindset, their balance barely budges. With a debt of $5,000 and a minimum monthly payment of $150 (at 3% of the total balance), they will only be paying $47.30 each month toward their principal. The rest goes toward their interest accrued.

Here’s what I had
Answer:
3 groups of 5
Explanation:
if x is the number of groups of four, and y is the number of groups of five, then 4x +5y =39 (four students per group of four times the # of groups of four, and 5 students per group times the # of groups of five, which should equal the total amount of students, 39). also, x+y=9. (number of each type of group = 9 groups total).
then, use these two equations and solve for y, by "canceling out" x. there are many ways to do this, but i'm going to use subtraction.
4x-5y=39
x+y=9
you want to change the equation
x+y=9
into
4x+4y=36
by multiplying the whole equation by four. because in order to cancel out the x, you need it to equal zero. in the first equation, its 4x.
so its now
4x-5y =39 MINUS
4x+4y=36
___________
y=3
you can check your work because the remaining 6 groups of four (24 total students) plus the 3 groups of five (15 total students) adds up to equal 36
