The area of the larger rectangle is 4 times the area of the smaller rectangle.
Calculate the dimensions of the smaller rectangle.
You must justify any decisions that you make.
9514 1404 393
Answer:
24 cm^2
Step-by-step explanation:
The larger rectangle has dimensions in cm of 12 by (4+x). The smaller rectangle has dimensions of (x+2) by x. The area of the larger is 4 times the smaller, so ...
12(4+x) = 4(x)(x+2)
3(4+x) = x(x+2) . . . . . . divide by 4
x^2 +2x -3x -12 = 0 . . . eliminate parentheses, subtract 3(4+x)
(x -4)(x +3) = 0 . . . . . . . factor
The positive solution is x = 4, so the area of the smaller rectangle is ...
x(x+2) = 4(4+2) = 24 . . . cm^2

Felix worked at a music shop during the summer. The table below shows some of Felix’s hours and earnings. The amount of money he earned is proportional to the number of hours he worked.
2. Let x represent the number of hours he worked, y represents the amount of money he earned.Write an equation that represents this relationship.
3. If Felix worked 180 hours, then how much money did he earn?
Answer:
2. y=9x
3. 180*9 = 1620
Step-by-step explanation:
2. y = mx+b, so find the slop efirst
lacampanella avatar
so take the first two points you got
lacampanella avatar
(2,18) and (5,45),
lacampanella avatar
(45-18)/(5-2) = 9
lacampanella avatar
then use (2,18)
lacampanella avatar
18= 9*2+b
lacampanella avatar
so b=0
3. y = 9x
x= 180. y = 9*180 = 1620

Answer: x= -7
Explanation for answer:
Answer:
x = -7
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
First, add 2x and subtract 18 from both sides:
5x - x + 18 (-18) (+2x) = 6 - 2x (+2x) - 30 (-18)
5x - x + 2x = 6 - 30 - 18
Next, simplify. Combine like terms:
(5x - x) + 2x = 6 + (-30 - 18)
(4x) + 2x = 6 + (-48)
6x = -42
Next, fully isolate the variable, x, by dividing 6 from both sides:
(6x)/6 = (-42)/6
x = -42/6 = -7
x = -7 is your answer.

Convert factored form to standard form
Answer:
[tex]y - 7x = 21[/tex]
Step-by-step explanation:
Given
[tex]y = (x + 4)7 - 7[/tex]
Required
Convert to standard form
[tex]y = (x + 4)7 - 7[/tex]
Start by opening the bracket
[tex]y = x*7 + 4*7 - 7[/tex]
[tex]y = 7x + 4*7 - 7[/tex]
[tex]y = 7x + 28 - 7[/tex]
[tex]y = 7x + 21[/tex]
Subtract 7x from both sides
[tex]y - 7x = 7x - 7x + 21[/tex]
[tex]y - 7x = 21[/tex]
Hence:
The standard form is: [tex]y - 7x = 21[/tex]
A group of friends wants to go to the amusement park. They have $94.25 to
spend on parking and admission. Parking is $14.75, and tickets cost $13.25
per person, including tax. Write and solve an equation which can be used to
determine p, the number of people who can go to the amusement park.
Answer:
1) The equation to determine the the number of people who can go to the amusement park is 14.75 + 13.25·p = 94.25
2) The number of people who can go to the amusement park is people
Step-by-step explanation:
The given parameters are;
The amount the group of friends have to spend on parking and admission = $94.25
The cost parking = $14.75
The cost of tickets per person = $13.25
The variable we let to represent the number of people who can go to the amusement park be "p"
1) The equation that can be used to determine "p" is therefore, given as follows;
14.75 + 13.25·p = 94.25
2) Therefore, we have, by making "p" the subject of the above equation;
p = (94.25 - 14.75)/13.25 = 6
Therefore, the number of people who can go to the amusement park, p = 6 people.
Answer:
Answer: 6
Step-by-step explanation:
Equation: 13.25p+14.75=94.25
Tell whether the angles are adjacent or vertical. Then find the value of x.
I finished the angles, but need the value of x.
Answer : The angles are vertical angles and the value of x is [tex]25^o[/tex]
Step-by-step explanation :
Adjacent angles : It is defined as the two angles that have the common arm and common vertex.
Vertical angles : It is defined as the two lines intersect each other and form angles. The opposite angles are known as vertically opposite angles.
And we know that the vertically opposite angles are equal.
In the given image, the angles are vertical angles and vertically opposite angles are equal.
So,
[tex](4x-25)^o=75^o[/tex]
[tex]4x-25^o=75^o[/tex]
[tex]4x=75^o+25^o[/tex]
[tex]4x=100^o[/tex]
[tex]x=\frac{100^o}{4}[/tex]
[tex]x=25^o[/tex]
Therefore, the angles are vertical angles and the value of x is [tex]25^o[/tex]

What will be the rule?
Step-by-step explanation:
it's rule is multiplying the in by 3
2 *3 = 6
4 * 3 = 12
7 * 3 = 21
9 * 3 = 27
Answer:
times 3
Step-by-step explanation:
ok so this is how I do it, I recommend it!
Look out the out number in the first number: 6
Ask yourself how to get from 6 to 2???......divided by 3 ofc!
Ok so then we see 4 and we multiply by 3=12
21 divided by 3 is 7! Rule right again!
27 divided by 3 is 9! Yay we did it!
Hope this helps :>

Maurice has completed 64 pages of the research paper he is writing. That is 80% of the required length of the paper. What is the required length of the paper?
Answer:
80 pages
Step-by-step explanation:
Let the required length of paper = x
Hence:
80% of x = 64 pages
80/100 × x = 64 pages
80x /100 = 64 pages
Cross Multiply
80x = 100 × 64 pages
x = 6400/80
x = 80 pages
Therefore, the required length of the paper = 80 pages
