Answer:
$4
Step-by-step explanation:
To answer, we have to find the base unit of how much each package would cost out of a box. To do this, we divide the total amount of the box of paper by how many packages were inside:
40 / 8 = 5
So, each package costed Ms. Jones $5, while the single packages cost $5.50, so Ms. Jones saved $0.50 per package she bought, which if you multiply by 8, you get 4, so Ms. Jones saved a total of $4.

Answer:
SAS for similarity
Step-by-step explanation:
I can tell you from this is that ∠TUS ≅ ∠WUV, because they are vertical angles.
The triangles cant be congruent by SSS, SAS, or ASA because the sides are not equal.
However, they are similar because 45/15 = 3 and 36/12 = 3. That would be the SAS for similarity.

Find the solution to the equation algebraically. Check your answer. k - 16 = 4
Answer:
k= 20
Step-by-step explanation:
You start with this equation:
k-16=4
Add 16 on both sides.
k=4+16
Simply.
k=20
If you want to check your answer, you can just plug 20 into where k is back into the equation:)
Hope this helps!
Hey there!
k - 16 = 4
ADD 16 to BOTH SIDES
k - 16 + 16 = 4 + 16
CANCEL out: -16 + 16 because it give you 1
KEEP: 4 + 16 because it give you the x-value
NEW EQUATION:
k = 4 + 16
k = 16 + 4
SIMPLIFY IT!
k = 20
Therefore, your answer is: k = 20
Good luck on your assignment & enjoy your day!

Write x² - 6x + 3 in the form (x-a)²+ b.
Answer:
(x + 3)² - 12
Step-by-step explanation:
x²+6x-3
= x²+ 6x + 9 - 12
= (x + 3)² - 12
The form of x² - 6x + 3 can be written as (x-3)² - 6.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given that;
Equation= x² - 6x + 3
Now,
To write x² - 6x + 3 in the form (x-a)²+ b, we can use the method of completing the square. This involves adding and subtracting a constant term to make the expression a perfect square trinomial. Here are the steps:
Write x² - 6x + 3 as x² - 6x + ___ - ___ + 3, leaving two blanks for the constant term.
To find the constant term, divide the coefficient of x by 2 and square it. In this case, -6/2 = -3 and (-3)² = 9. So we fill in the blanks with 9 and get x² - 6x + 9 - 9 + 3.
Factor the first three terms as a perfect square: (x - 3)² - 9 + 3.
Simplify the last two terms: (x - 3)² - 6.
Compare with the form (x-a)²+ b and identify a and b. In this case, a = 3 and b = -6.
Therefore, by the given equation the answer will be (x-3)² - 6.

Write a system of linear inequalities so the points (1, 2) and (4, −3) are solutions of the system, but the point (−2, 8) is not a solution of the system. PLEASE SOMEONE HELP AND SOLVE IT AS A SYSTEM OF LINEAR EQUATIONS
Answer:
The sample system is given below:
y < 5 y > x - 8see the attached for the graph
The points (1, 2) and (4, -3) are in the intersected region but the point (-2, 8) is outside
The easy way to get the inequalities to plot the points and add lines to divide the regions where desired point are inside and not required point is outside. I put y = 5 and y = x - 8 lines and shaded the region below y = 5 line and above the other line.
