Answer:

8

Step-by-step explanation:

  • Divide, if possible. Check each answer. -144-:18

assuming the question is -144 : (-18) and not -144-:18

-144 : (-18) = 8

check

8 × (-18) = -144

Are all lines of symmetry also diagonals? Please help!!!

Answers

I think no, now all lines of symmetry are diagonals because it can also be horizontal and vertical.
Symmetry is also known as proportion; anything that is equal or proportion with each other.
Let’s have an example:
A square
=> in getting the symmetry of a square, we need to draw a 2 diagonal lines to each edges.
=> we can also draw 2 perpendicular lines that bisect to the edges of the square and it also provide an equal parts or proportional parts.







Answer:

i just looked it up kk

Explanation:

Not all lines that divide a figure into two congruent halves are lines of symmetry. The diagonal of a rectangle divides the rectangle into two triangles that are congruent (same size and shape). But the diagonal line is NOT a line of symmetry. ... The parallelogram, however, has NO lines of symmetry.

Two classes have a total of 50 students. One of the classes has 6 more students than the other. How many students are in the larger class.

Answers

Let's say 'x' to number of the students in the smaller class. Since the larger one is 6 more than the smaller one, its number would be 'x+6'. So their sum is equal to 

x+x+6=2x+6 and we know total is 50 so:
2x+6=50\n 2x=50-6\n 2x=44\n x=\frac { 44 }{ 2 } \n x=22 

x is 22 so the larger number 'x+6' is equal to : x+6=22+6=28

There are 28 students in the larger class.

Let's assume the number of students in one class is x.

Since the other class has 6 more students, the number of students in the other class is x + 6.

The total number of students in both classes is 50.

Therefore, we can write the equation:

x + (x + 6) = 50

2x + 6 = 50

Subtracting 6 from both sides:

2x = 44

Dividing both sides by 2:

x = 22

So, the number of students in the larger class, which is x + 6, is:

22 + 6 = 28

Therefore, there are 28 students in the larger class.

Sally needs to have some drywall and insulation work done in her house. She has received a quote from a professional drywall contractor to complete her repairs for $1,200. Her neighbor Steve says he can complete the same job for $800. Sally could use a credit card to pay the contractor, but Steve can only accept cash. Sally’s credit card has a 14% APR for credit purchases and a 32% interest rate for cash advances. Expecting to pay $50 of the principle plus appropriate interest each month, Sally estimates that it would take her 24 months to pay off the contractor balance and 16 months to pay off the cash advance balance. In the end, would it be cheaper for Sally to hire the contractor or her neighbor to complete the repairs?
