Step-by-step explanation:
The trick here is to identify the greatest common factor of 60 and 28. 4 is such a factor. We can therefore rewrite 60x + 28y as
4(15x + 7)
There are other possible answers.
600x + 280y

What is the point-slope form
Answer:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). Watch this video to learn more about it and see some examples. Created by Sal Khan.

Step-by-step explanation:
Uh please help me, I need a step by step answer.
Answer:
B 1296
Step-by-step explanation:
Area of a rectangle = Length × Width
Area of a triangle = [tex]\frac{1}2[/tex] × Base × Height
3 sides are rectangles with the measurements of (9mm by 21mm)
So 3(9 × 21) = 567mm^2
6 sides are rectangles with the measurements of (9mm by 9mm)
So 6(9 × 9) = 486mm^2
1 side is a rectangle with the measurements of (9mm by 15mm)
So (9 × 15) = 135mm^2
2 sides are triangles with unknown, but equal bases.
To calculate the base, you subtract 9 from 21: 21 - 9 = 12mm
Therefore the base = 12mm
The other measurement can be found by looking to the left of the triangle (9mm from the side)
So 2([tex]\frac{1}2[/tex] × 12 × 9) = 108mm^2
Add the sides up:
567 + 486 + 135 + 108 = 1296 mm^2

30% of the scholars are working as stagehands. 35 scholars are actors and actresses. How many students in total are in the school play, acting and working behind the scene?
Answer:
There are 50 students in total in the school play, acting and working behind the scene.
Step-by-step explanation:
Since the statement indicates that 30% of the scholars are working as stagehands, you can subtract this from 100% that represents the total amount of student in the school play to find the percentage that are actors and actresses:
100%-30%=70%
Now, as you know that 70% of the students are actors and actresses and the statement indicates that they are 35, you can use a rule of three to find the amount of students that represent 100%:
70% → 35
100% → x
x=(100*35)/70
x=50
According to this, the answer is that there are 50 students in total in the school play, acting and working behind the scene.

Solve for a. -4a - 2a – 7 = 11 a = [?]
Answer:
a = -7/17
Step-by-step explanation:
Add -4a to -2a
This makes -6a. Then you add 6a to the left to cancel it out, but you must also add 6a to the right of the =
Then you have -7 = 17a
Divide 17 from both sides and you have -7/17 = a
Parallelogram FIRE
Given:
[tex]fi = (3x - 5) \: cm[/tex]
[tex]ir = (2y - 7) \: cm[/tex]
[tex]re = (x + 7) \: cm[/tex]
[tex]ef = (y + 3) \: cm[/tex]
a. What is the value of x?
b. How long is FI?
c. What is the value of y?
d. How long is EF?
e. From your answers in b and d, what is the perimeter of parallelogram FIRE?
Answer:
See the solutions below
Step-by-step explanation:
First note that the opposite side of a parallelogram are equal, hence;
For Parallelogram FIRE
fi = re
ef = ir
Given
fi = (3x-5)cm
ir = (2y -7)cm
re = (x+7)cm
ef = (y+3)cm\
a) If fi = re, then;
3x - 5 = x+7
3x - x = 7+5
2x = 12
x = 12/2
x = 6
b) Since FI = 3x - 5
FI = 3(6) - 5
FI = 18 - 5
FI = 13cm
c) Also ef = ir
y+3 = 2y - 7
y - 2y = -7-3
-y = -10
y = 10
d) EF = y+3
EF = 10 +3
EF =13cm
e) Perimeter of the parallelogram = FI + IR + RE + EF
Perimeter of the parallelogram = 13cm + 13 + 13cm + 13cm
Perimeter of the parallelogram = 52cm

Answer:
4x^2 - 12x +9
Step-by-step explanation:
The figure is a square.
the area of a square is = side^2
area = (2x-3)^2 = 4x^2-12x +9
thanks to rule of the square of a binomial, we can skip this passage:
(2x-3)(2x-3) = 4x^2-6x-6x+9 =4x^2-12x +9
Answer:
4x²−12+9
Steps:
2x(2x−3)−3(2x−3)
4x²−6−3(2x−3)
4x²−6x−6x+9
4x²−12x+9

________
440,000
You could work from the ones to the hundred thousandths.
First add the zeros, then work to the thousandths. 0+0=0, 0+0=0,0+0=0,0+0=0,0+4=4, 4+0=4.
Therefore, 400,000+40,000=440,000.

The area of a square photo frame is 144 cm2 . Find the perimeter of the photo fame, leaving your answer correct to 1 decimal place
Answer:
48 cm
Step-by-step explanation:
If it's square and the area is 144, then the sides are each 12cm (a = l x w, 144 = 12 x 12)
12cm x 4 sides = 48cm
Answer:
48
Step-by-step explanation:
The area is 144 cm².
A = s²
144 = s²
[tex]\sqrt{144\\}[/tex] = s
12 = s
photo frame is a square.
perimeter of a square = 4 * s
P = 4 *s
P = 4 (12)
P = 48

A rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. If we choose "down" as positive and ignore air friction, the function is
Answer: 2.49 s
Step-by-step explanation:
Given
Rock is dropped from a height of [tex]h=100\ ft[/tex]
Using the equation of motion [tex]h=ut+\frac{1}{2}at^2[/tex]
here, [tex]u=0[/tex] (Rock is dropped)
[tex]a=g[/tex]
Putting values
[tex]\Rightarrow 100=0+\dfrac{1}{2}gt^2\\\\\Rightarrow t^2=\dfrac{2h}{g}=\dfrac{2\times 100}{32.2}\\\\\Rightarrow t=\sqrt{6.211}=2.49\ s[/tex]

A cylinder has a diameter of 10 units,
Its radius is
units. If its height is twice its radius, its height is
✓ units. Its volume is about
cubic units
Reset
Next
Answer:
the volume of the cylinder is 785 units^2
Step-by-step explanation:
The computation of the volume of the cylinder is shown below:
Given that
The diameter is 10 units
So, the radius is half of the diameter i.e. 5 units
The height would be twice of the radius i.e. 10 units
Now the volume of the cylinder is
=πr^2h
r denotes the radius
And h denotes the height
= 3.14 × 5^2 × 10
= 785 units^2
Hence, the volume of the cylinder is 785 units^2

Hey there!
[tex]\tt{\dfrac{\dfrac{1}{x^2} + \dfrac{2}{y}}{\dfrac{5}{x} - \dfrac{6}{y^2}}}[/tex]
So, what we can do here is first take the Least Common Multiple here, on both Numerator and Denominator.
[tex]\tt{\dfrac{\dfrac{y + 2y^2 (1)}{x^2 y (2)}}{\dfrac{5y^2 - 6x (3) }{xy^2 (4)}}}[/tex]
[The number in brackets is for the next step :-
When we will further simplify it, we will multiply 1st with 4th and 2nd with 3rd.
[tex]\tt{\dfrac{y + 2y^2 \times xy^2 }{x^2 y \times 5y^2 - 6x }}[/tex]
[tex]\tt{\dfrac{y + 2y^2 \times y }{x \times 5y^2 - 6x }}[/tex] is the framed answer.
Answer:
[tex]\frac{y(y+2x^2)}{x(5y^2-6x}[/tex]
Step-by-step explanation:
Lets do the numerator and denominator seperately:
Numerator:
1/x^2 + 2/y
Find common denominator and add these 2 fractions:
This is x^2y (I just multiplied the 2 denominators together’
Now, do what you have done to x^2 to make it x^2y, ie. multiplied by y, to the 1. This = y
And do what you have done to y to make it x^2y, ie. multiplied by x^2, to the 2. This = [tex]2^{2}[/tex]
Now, arrange all numbers we have found into the correct order in the fraction. This is:
[tex]\frac{y+2x^{2}}{x^{2} y}[/tex]
Denominator:
5/x - 6/y^2
Find the common denominator and subtract these two fractions:
This is xy^2
Now, do what you have done to x to make it xy^2, ie. multiply by y^2, to the 5. This = 5y^2
And do what you have done to the y^2 to make it xy^2, ie. multiply by x, to the 6, this is = 6x
Now, arrange all the numbers we have found into the correct order in the fraction
[tex]\frac{5y^{2}-6x}{xy^2}[/tex]
Now that we have the numerator and the denominator, we can solve the equation.
The original question asks us to divide the 2 fractions, so:
[tex]\frac{y+2x^{2}}{x^{2} y}[/tex] divided by [tex]\frac{5y^{2}-6x}{xy^2}[/tex]
For the division of fractions, you just have to multiply the inverse of the 2nd fraction by the first, so
[tex]\frac{y+2x^{2}}{x^{2} y}[/tex] x [tex]\frac{xy^2}{5y^2-6x}[/tex]
Use cross multiplication to simplify the above expression to:
[tex]\frac{y(y+2x^2)}{x(5y^2-6x}[/tex]
Hope this helps, sorry its long ...
