2. The width of a rectangle is 5 units less than the length. If the area is 150 square units, then find the dimensions of the rectangle
Answer:
[tex] \boxed{Dimensions\: of \: the \: rectangle \: are \: 15 \: and \: 10 units} [/tex]
Step-by-step explanation:
Let the length of rectangle be 'x' units
So, width of rectangle will be = x - 5 units
Area of rectangle = 150 square units
[tex]=> Area \: of \: rectangle = length × breadth \\ \\ = > 150 = x \times (x - 5) \\ \\ = > 150 =( x \times x )- (x \times 5) \\ \\ = > 150 = {x}^{2} - 5x \\ \\ = > 0 = {x}^{2} - 5x - 150 \\ \\ = > {x}^{2} - 5x - 150 = 0 \\ \\ = > {x}^{2} - (15 - 10)x - 150 = 0 \\ \\ = > {x}^{2} - 15x + 10x - 150 = 0 \\ \\ = > x(x - 15) + 10(x - 15) = 0 \\ \\ = > (x - 15)(x + 10) = 0 \\ \\ = > x - 15 = 0 \: \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: \: x + 10 = 0 \\ \\ = > x = 15 \: \: \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: \: x = - 10[/tex]
Dimension cannot be negative so the value of x is 15
Therefore,
Length of rectangle = 15 units
Width of rectangle = 15 - 5 = 10 units

14. Number Sense Jorge collects sports
cards. He displays his cards in an album.
There are 72 pages in the album. Each
page holds 9 cards. Find the number of
cards in the album if half of the pages
are full and the rest are empty.
Answer: 324 cards.
Step-by-step explanation:
Hi, to answer this question we have to multiply the number of pages in the album (72) by the number of cards that each page holds (9):
Mathematically speaking:
72(9) = 648 cards in the album
Since half of the pages are full, we have to divide the previous result by 2.
648/2 = 324 cards

11. Write an equation for a line that is parallel to the line 6x - 3y = 15 and goes through the point
(-2,4).
Answer:
y = 2x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
6x - 3y = 15 ( subtract 6x from both sides )
- 3y = - 6x + 15 ( divide all terms by - 3 )
y = 2x - 5 ← in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (- 2, 4) into the partial equation
4 = - 4 + c ⇒ c = 4 + 4 = 8
y = 2x + 8 ← equation of parallel line
The required equation of the parallel line is,
[tex]6x-3y+24=0[/tex]
Equation of parallel lines:
Parallel lines are lines that never intersect. Because of this, a pair of parallel lines have to have the same slope, but different intercepts (if they had the same intercepts, they would be identical lines).
Given, the equation of the line is [tex]6x-3y=15[/tex]
Let the equation of the parallel line be,
[tex]6x+3y+k=0[/tex]...(1)
Since, the equation (1) passes through the point (-2,4) then,
[tex]6(-2)-3(4)+k=0\\-12-12+k=0\\k=24[/tex]
Now, substituting [tex]k=24[/tex] in equation (1) we get,

A rectangle with perimeter 30 in. has length 10 in. What is the area of the rectangle?
Answer:
Length of rectangle = 10in.
Breadth " " =x
Perimeter= 2( l+b)=30in.
Perimeter=2(10+b)=30in.
=(10+b)=30/2=15
=b=15-10
Breadth=5in.
Answer: 50 in²
Explanation: Remember that the formula for the area of a rectangle is length · width so we need to find the width of the rectangle.
To find the width of the rectangle, let's use our formula
for the perimeter of a rectangle which is 2l + 2w.
Since we know that the perimeter of the rectangle is 30 inches and the length of the rectangle is 10 inches, we have 30 = 2(10) + 2w.
Simplifying on the right side gives us 30 = 20 + 2w.
Now subtract 20 from both sides to get 10 = 2w.
Finally, dividing both sides by 2, we find that 5 = w.
So the width of the rectangle is 5 inches and remember
that the length of the rectangle is 10 inches.
So the area of the rectangle, l · w, is 10 · 5 or 50 in².

A local kids play sold 8 adult tickets and 9 child tickets for a total of $205. On day two they sold only 4 adult tickets and 3 child tickets for a total of $83. What was the price of each kind of ticket?
Answer:
The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13
Step-by-step explanation:
Let x be the cost of 1 adult ticket
Let y be the cost of 1 child ticket
Cost of 8 adult tickets = 8x
Cost of 9 child tickets = 9y
We are given that A local kids play sold 8 adult tickets and 9 child tickets for a total of $205
So, 8x+9y=205 ----- 1
Cost of 4 adult tickets = 4x
Cost of 3 child tickets = 3y
We are given that 4 adult tickets and 3 child tickets for a total of $83.
4x+3y=83 ----2
Plot 1 and 2 on graph
8x+9y=205 -- Red line
4x+3y=83 -- Blue line
Intersection point provides the solution
So, Intersection point =(11,13)
So, The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13

What is the slope of the graph ? I have no time limit. Thank you to anyone who answers!
Answer:
The slope is 1
Step-by-step explanation:
Pick two points
(-1,0) and (0,1)
The slope is given by
m= (y2-y1)/(x2-x1)
= (1-0)/( 0 - -1)
= (1-0)/(0+1)
= 1/1
1
Hello there!
Y = mx + b
Looking at the graph we can find our y-intercept, which would be 0,1.
To find the slope, we can use any two coordinates on the line, such as
(-1,0) and (0,1).
Plug it into the slope formula: rise over run.
1 - 0 / 0 - - 1 = 1/1
1/1 = 1
Therefore our slope is 1x.
Lastly, we just plug the values in for our slope intercept form.
y = 1x + 1

Answer:
Step-by-step explanation:
7a - 3 = 3 + 6a
7a = 6 + 6a
a = 6
Answer:
a = 6, Nice work!
Step-by-step explanation:
7a - 3 = 3 + 6a
First step is to subtract 6a from the right, also subtracting it from the left. This will leave you with:
a -3 = 3
Now you need to isolate the variable, so to get rid of -3, you have to add 3 to both sides.
a -3 = 3

Complete Question
To decorate for a party, Rob and Loretta were each given a bag of balloons. There were 40 balloons between both bags. Rob used 8 balloons from his bag, and Loretta used 8 balloons from hers. The product of the number of balloons left in each bag is no more than 44.
Let x represent the number of balloons that Rob had in his bag before he used any. Which choice represents the number of balloons left in their bags?
A. x² - 40x - 300 = 0
B. x² - 40x - 300 < 0
C. x² - 40x = 300
D. x² - 40x + 300 ≥ 0
If Rob originally had more balloons than Loretta, what is the least number of balloons that Rob could have had before using any?
A.30
B.20
C.10
Solution
If x is the number of balloons that Rob had at the start, the number of balloons that Loretta would have at the start = (40 - x)
Then, they both use 8 balloons each for their designs,
The number of balloons Rob has after the design = (x - 8)
The number of balloons Lorretta has after the design = (40 - x - 8) = (32 - x)
The product of the balloons left isn't more than 44
(x - 8) × (32 - x) ≤ 44
32x - x² - 256 + 8x ≤ 44
44 ≥ -x² + 32x + 8x - 256
44 ≥ -x² + 40x - 256
44 + x² - 40x + 256 ≥ 0
x² - 40x + 300 ≥ 0
To solve the second part of the question, we just solve the expression obtained in the first part.
x² - 40x + 300 ≥ 0
Simplifying the left hand side
(x - 30)(x - 10) ≥ 0
The solutions of the inequality is
x ≤ 10 or x ≥ 30
Hence, if Rob had more balloons than Loretta, the feasible solution for x would be x ≥ 30 and the least number of balloons that Rob van have before using any = 30.
Hope this Helps!!!
Answer:

Step-by-step explanation:
Answer:
1) Option D is the right answer.
x2 - 40x + 300 0 is the option that reflects the number of balloons in their bags.
2) Option A is the right answer.
If Rob had more balloons than Loretta, the minimum number of balloons Rob could have before using any would be 30.
Step-by-step instructions:

Loretta used 8 balloons from her bag, while Rob used 8 from his.The total number of balloons left in each bag cannot exceed 44. Let x be the number of balloons in Rob's bag before he utilized any of them. Which option best depicts how many balloons they still have in their bags? x2 - 40x - 300 = 0 A. x2 - 40x - 300 0 x2 - 40x - 300 0 x2 - 40x - 300 0 x2 C. 40x - x2 = 300 x2 - 40x + 300 0 x2 - 40x + 300 0 x2 - 40x + 300 0 x2 What is the smallest number of balloons that Rob has if he started with more than Loretta? What is the smallest number of balloons Rob could have had before using any if he had more than Loretta at the start? Solution A.30 B.20 C.10 If x is the number of balloons Rob had at the start, Loretta's number of balloons at the start would be = (40 - x) Then they each use eight balloons to create their creations. After the design, the number of balloons Rob possesses Equals (x - 8) Then there was (40 - x - 8) = the amount of balloons Lorretta possesses after the design (32 - x) The product of the remaining balloons is just 44. (x - 8) (32 - x) 44 x x x x x x x x x x x 32x - x2 - 256 + 8x 44 44 -x2 + 32x + 8x - 256 44 -x2 + 32x + 8x - 256 44 -x2 + 40x - 256 x2 - 40x + 256 0 x2 - 40x + 300 0 44 + x2 - 40x + 256 0 We just solve the equation acquired in the first half of the question to solve the second portion of the question. x2 - 40x + 300 ======================== Simplifying...
(x - 30)(x - 10) 0 (x - 30)(x - 10) 0 (x - 30)(x - 10) 0 (x - 30)(x - The inequality's solutions are x 10 or x 30. As a result, if Rob has more balloons than Loretta, the viable solution for x is x 30, and the smallest number of balloons Rob may have before using any is 30. I hope this information is useful!!! ⭐️
