Answer:
r = -1
Step-by-step explanation:
-6 + 4r = 2(r - 4)
-6 + 4r = 2r - 8
+6 +6
4r = 2r - 2
-2r -2r
2r = -2
/2 /2
r = -1

Answer: Food Saver
Step-by-step explanation:
A 5-pound bag at Bargain Mart costs $6.45. The coat per pound will be:
= $6.45 / 5
= $1.29
A 2-pound bag at Food Saver costs $2.50. The cost per pound will be:
= $2.50 / 2
= $1.25
A 7-pound bag at Grocery Surplus costs $9.45. The cost per pound will be:
= $9.45 / 7
= $1.35
A 10-pound bag at Economart costs $12.89. The cost per pound will be:
= $12.89 / 10
= $1.289
Therefore, the shop which sells flour for the lowest unit price is Food Saver.
A parallelogram has a base of 9 and a corresponding height of 2/3. What is the area?
Therefore area of a parallelogram = 6
Given the base of a parallelogram = 9
Height of a parallelogram = 2/3
We have to find the area of the parallelogram as
The formula for the area of the parallelogram as base * height
By using the above formula we get
Area of parallelogram = base * height
= 9 * 2/3
= 3 * 2
= 6
Therefore area of a parallelogram = 6

A pair of equations is shown below:
y = 3x − 5
y = 6x − 8
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answer:
Part A: You can solve this by elimination by first multiplying the first equation by -1 and then adding. This will cause the y value to cancel out.
-y = -3x + 5
y = 6x - 8
---------------
0 = 3x - 3
3 = 3x
1 = x
Now since we know that x = 1, we can plug it into either equation to find y.
y = 3x - 5
y = 3(1) - 5
y = 3 - 5
y = -2.
This gives us the ordered pair of (1,-2).
Step-by-step explanation:
Part B: If we graphed these two, they would intersect at (1, -2). This is because when you solve a system using any method, the result is the intersection of the lines. Therefore, you found where they would intersect in Part A.

The same business recently upgraded a display TV they had in their lobby.
Originally the TV was 32 inches (across the diagonal) and had an area of
446.38in? The new TV is 53 inches across the diagonal. What is the area of the
new TV? Round the answer to two decimal places.
Answer: 739.32in
Step-by-step explanation:
Since we are informed that originally the TV was 32 inches (across the diagonal) and had an area of
446.38in while thee new TV is 53 inches across the diagonal.
The area of the new TV would simply be calculated as:
= (53 × 446.38) /32
= 23658.14 / 32
= 739.32in
A group of 48 senior citizens attended a baseball game. The number of women in attendance was 12 more than the number of men. How many men and women attended the baseball game?
Answer:
18 men attended the baseball game, and 30 women attended the baseball game.
Step-by-step explanation:
Let the number of men in attendance be x and the number of women in attendance be x+12.
No. of men + No. of women = 48
x + x + 12 = 48
2x + 12 = 48
2x = 48 - 12
= 36
x = 36 ÷ 2
x = 18
x+12: 18 + 12 = 30

How many solutions are there to this equation? 5x + 2-2(x - 1) = 3x + 4*
Ono solution
O exactly one solution
O at least two solutions
Oinfinitely many solutions
The equation 5x ₊ 2 ₋ 2(x₋1) = 3x ₊ 4 has infinitely many solutions. Examining our findings will allow us to determine which case it is. There are endless solutions if we end up with the identical term on both sides of the equal sign, such as 3 = 3 or 2x = 2x. There are no solutions if we end up with different integers on either side of the equal sign, as in 6 = 5.
Given the equation is 5x ₊ 2 ₋ 2(x₋1) = 3x ₊ 4
First apply the multiplicative distribution law.
5x ₊ 2 ₋ 2x ₊ 2 = 3x ₊ 4
now rearrange the unknown terms to the left side of the equation:
5x ₋ 2x ₋ 3x = 4 ₋ 2 ₋ 2
combine like terms.
0 = 4 ₋ 2 ₋ 2
0 = 0
we get the similar value on both sides of the equal sign, which indicates that the equation has infinitely many solutions.
hence the equation has infinitely many solutions.
