Answer:
x=63
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
Given
3 - 4x = - 60 + 3x ( subtract 3x from both sides )
3 - 7x = - 60 ( subtract 3 from both sides )
- 7x = - 63 ( divide both sides by - 7 )
x = 9
how do i simplify this
3xy (5x2 + 2xy + 3y2)
Answer:
15x^3y+6x^2y^2+9xy^3

A video store charges $8 to rent a video game. You must be a member to rent from the store, but
the membership fee is free. Another video store in town charges only $3 to rent a video game for a
5 day period, but membership in this store is $50 per year. Which rental plan is more economical?
Explain in detail and give examples.
Answer:
The $3 per video game with $50 membership is more economically if you rent at least 11 games or more per year
Step-by-step explanation:
there are 365 days in a year
3 x 365 = 1095
1095 + 50 = $1145 (Cost per year)
8 x 365 = $2920 (Free Membership) cost per year
If you only rent 10 video games per year, they equals the same amount
$3 x 10 (games) = $30 Then $30 + $50 (Member Fee) = $80
$8 x 10 (games) = $80 for 10 games rental
If they rent 11 games or more per year, then the $3 rental is more economical.
$3 x 11 = $33; $33 + 50 = $83
$8 x 11 = $88

Answer:
Each side is 15 ft
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
225 ft^2 = s^2
Take the square root of each side
sqrt ( 225 ft^2) = sqrt ( s^2)
15 ft = s
Each side is 15 ft

A. Definition of Angle Bisector
B. Segment Addition Property
C. Definition of Congruent Angles
D. Transitive Property
Answer:
The following property: If a = b and b = c, then a = c. One of the equivalence properties of equality. Note: This is a property of equality and inequalities.
Congruent Angles have the same angle (in degrees or radians). That is all. These angles are congruent. They don't have to point in the same direction. They don't have to be on similar sized lines.
The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.Jan 4, 2016
The (interior) bisector of an angle, also called the internal angle bisector (Kimberling 1998, pp. 11-12), is the line or line segment that divides the angle into two equal parts. The angle bisectors meet at the incenter.
Step-by-step explanation:
geometrical prove that limit X tends to zero sin x by X equals to 1 various is measured in radian
[tex]lim \frac{ \sin(x) }{x} = 1 \\ [/tex]
It is true only whenever x tends to 0(zero)
it is not importent that x be in radian or in degree.
samantha has 20 marbles paul has m marbles. Of samantha has 6 times as many marbles as paul, write an equation to show how many marbles paul has?
Answer:
20 = 6m or m = 20/6 = 10/3
Step-by-step explanation:
Let's say Samantha has s marbles and Paul has m marbles.
We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.
Substitute 20 in for s:
20 = 6m
m = 20/6
Thus, the equation is m = 20/6.
~ an aesthetics lover
Answer:
20 = 6m or m = 20/6 = 10/3
Step-by-step explanation:
You see 6m or m is equal to 20

Jennifer is saving money to buy a bike. The bike costs $282. She has $128 saved, and each week she adds
$14 to her savings.
How long will it take her to save enough money to buy the bike?
Answer:
11 weeks
Step-by-step explanation:
$282 = $128 + 14w
$282 -$128 = $14w
$154 = $14w
14 = 14
11 = w
Jessie loves to go hiking on rustic trails through trees and along rivers.One day in 20 minutes of hiking, she hiked 1 mile. If Jessie hiked at a constant rate, what would that rate be?Write Jessie's hiking rate in all the ways you can think of from the information given. *
Answer:
Jessie hiked at a constant rate of 3 miles/hour
Step-by-step explanation:
Constant rate can also be called speed
The formula for constant rate /Speed = Distance (miles)/ time in hours
Distance = 1 mile
Time = 20 minutes
Converting to hours
60 minutes = 1 hour
20 minutes =
20/60
= 0.3333333333hour
Constant rate = 1mile/0.3333333333 hour
= 3.0000000003
= 3 miles/hour

Michael received a grant to make a community garden. He makes a scale drawing of his vision for the garden. Michael's drawing shows the layout of 9 raised garden beds of the same size. The scale from his drawing to the actual garden is 2 cm for every 1 ft. What is the actual area of one of the garden beds? (HINT: the formula is A = L x W. How many things do you need to find?)
Step-by-step explanation:
Find the diagram to the question attached.
From the diagram, we are given the following dimension for one of the beds;
Length = 16cm
Width = 8cm
If the scale from his drawing to the actual garden is 2 cm for every 1 ft, then on converting to feet;
2cm = 1ft
16cm = x fr
cross multiply
2x = 16
x = 8ft
Hence 16cm = 8ft (based on the scale)
Similarly:
2cm = 1ft
8cm = x fr
cross multiply
2x = 8
x = 4ft
Area of the garden bed (in feet) = Length * Width
Area of the garden bed = 8ft * 4ft
Area of the garden bed = 32ft²
Hence the actual area of one of the garden beds is 32ft². We need to find 2 things fir us to get the required answer. First is the length of the bed in feet and the second is the width of the bed in feet.
Write an equation for the line that passes through the points (1,4) and (2, -4).
Answer:
-8
Step-by-step explanation:
We can use the formula [ y2-y1/x2-x1 ] to solve.
-4-4/2-1
-8/1
-8
Best of Luck!
First of all, Let's find the slope because we need it on the formula for finding the y-intercept.
m = y2 - y1 / x2 - x1
From the points given in the question,
x1 = 1
x2 = 2
y1 = 4
y2 = -4
Plugging in the above formula,
➝ m = -4 - 4 / 2 - 1
➝ m = -8 / 1
➝ m = -8
Now finding the y-intercept[tex]:[/tex]
➝ y = mx + b
And if we put in the values from our first point (1, 4) we get
➝ 1 = -8 (4) + b
➝ 1 = -32 + b
➝ b = 1 + 32
➝ b = 33
Required equation of the line:
➝ y = -8x + 33

evaluate f(3) for the function f(x)= 15x^2 -x+20
Answer:
[tex] \huge \boxed{f(15) = 152 }[/tex]
Step-by-step explanation:
[tex]f(x) = 15 {x}^{2} - x + 20[/tex]
To find f(3) , substitute the value of x that's 3 into f(x). That is for every x in f(x) replace it with 3.
We have
[tex]f(15) = 15( {3})^{2} - 3 + 20 \\ \: \: = 15(9) + 17 \\ = 135 + 17 \: \\ = 152 \: \: \: \: \: \: \: \: \: \: [/tex]
We have the final answer as
[tex]f(15) = 152 [/tex]
