Answer:
Infinite number of solutions
Step-by-step explanation:
Let's start by simplifying this by combining like terms
on the left side
9x+5-2x-8=
7x-3
on the right side
-5+7x+2
7x-3
put these together and get
7x-3=7x-3
these are obviously identical which means that there are an infinite number of solutions

Answer:
24.5 kJ
Step-by-step explanation:
Kinetic energy is given by the formula ...
KE = 1/2mv² . . . . . where m = mass
The gazelle's kinetic energy is ...
KE = 1/2(40 kg)(35 m/s)² . . . . . where m is meters

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes,and 20 pages in 30 minutes. Is this a proportional relationship? If so, what is the constant of proportionality? What does it represent? Write an equation to represent this situation.
Answers
Answer:
y = 2/3xStep-by-step explanation:
Reading rate is y pages per x minutes and proportional relationship formula is:
y = kxThe coefficient is:
k = y/xLet's verify if the given numbers fit into the same relationship:
12/18 = 2/38/12 = 2/320/30 = 2/3We confirm all same and it means k = 2/3
Required equation is:
y = 2/3xThis represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages

8 Black pencils cost 15e cach and coloured
pencils cost 2lc cach. Ir 24 pencils cost
$4,02, how many of them were black (Hint
let there be + black pencils. Thus there are
24 – x coloured pencils. Work in cents.)
of
Answers
Answer:
17 black pencils
Step-by-step explanation:
Cost of black pencils; 15 cents each
Cost of colored pencils; 21 cents each
We are told that 24 pencils cost $4.02 = 402 cents
Let black pencils be x and let colored pencils be y.
Thus;
x + y = 24 - - - (eq 1)
Also,
15x + 21y = 402 - - - (eq 2)
From eq 1, y = 24 - x
Thus putting it in eq 2 gives;
15x + 21(24 - x) = 402
15x + 504 - 21x = 402
504 - 402 = 6x
x = 102/6
x = 17
What is the solution to -2(2x - 3)= 4 - (3x + 5)?
Answers
Answer:
x=7
Step-by-step explanation:
expand -2(2x-3): -4x+6
expand 4-(3x-5): -3x-1
it's now -4x+6=-3x-1
subtract 6 from both sides
-4x+6-6=-3x-1-6
simplify
-4x=-3x-7
add 3x to both sides
-4x+3x=-3x-7+3x
simplify
-x=-7
divide both sides by -1
[tex]\frac{-x}{-1}[/tex]=\ [tex]\frac{-7}{-1}[/tex]

if mr. Wells goes out to dinner and his bill comes to $25.67 and the tax rate is 3.5% how much tax will be added bill
Answers
okay so basically its an increase of 3.5% of 25 dollars and 67 cents.
So
basically
(25.67)* .035 -----> To get .035, you will need to move the decimal to the left twice to make it into a decimal to get the percentage of the total amount.
So the total of that amount would be
89 cents ( ignore numbers after 9 because your just looking at the 2 first number after you did your equation).
Then you add the total amount ( The amount for the meal) + The TAX
So you will get 25.67 + 89 = 26.56
If you got any more questions of what I said ( because it's confusing). Tell me!
ANSWER: $26.56
25.67+0.89= 26.56$
Use the square root property to solve: 5x^2+8 =133

Answers
Answer:
x = ± 5Step-by-step explanation:
See the steps
5x^2+8 = 1335x^2 = 133 - 85x^2 = 125x^2 = 125/5x^2 = 25√x² = √25x = ± 5Answer:
x=5
x=−5
Step-by-step explanation:
5x^2+8 =133
Subtract 8 from both sides.
5x^2=133−8
Subtract 8 from 133 to get 125.
5x^2=125
Divide both sides by 5.
x^2=125/5
Divide 125 by 5 to get 25.
x^2=25
Take the square root of both sides of the equation.
x=5

Please help me, I'm giving away the rest of my points for this 2 part question..
for the second part the answer choices are
A: Right
B: Obtuse
C: Isosceles
D: Equilateral
Answers
Answer:
First part
angle ABC=94 degrees
angle BCD=25 degrees
angle ACB=43 degrees
Second part
C) isosceles and obtuse because angle ABC is greater than 90 degrees and angle ACB=angle CAB
Step-by-step explanation:
All triangles contain 180 degrees.
Triangles ADB and CDB are congruent because side-angle-side theorem.
Since angle ABD=133 degrees, angle CBD=133 degrees because corresponding angles of congruent triangles are equal.
angle ABC=360-133-133=94 degrees
angle BCD=180-133-22=25 degrees
angle ACB=(180-94)/2=43
Angle BCD = 180 - (22+133) = 25 degrees
Angle ACD = (180-44)/2 = 68
Angle ACB = 68-25 = 43 degrees
For the second part, triangle ABC is isosceles

The sum of four consecutive integers is 170. Write an equation that can be used to find the smallest integer.
Answers
Answer:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41
Step-by-step explanation:
Four consecutive integers is represented by:
First Integer = x
Second Integer = x + 1
Third Integer = x + 2
Fourth Integer = x + 3
The sum of four consecutive integers is 170.
x + x + 1 + x + 2 + x + 3 = 170
The Equation to find the smallest integer =
4x + 6 = 170
4x = 170 - 6
4x = 164
x = 164/4
x = 41
Therefore:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41

Please answer as quickly as you can! ♥ Find two possible dimensions for a cylinder that has a volume of 64π cm³.
Answers
Answer:
Possible dimensions are [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex] and [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]
Step-by-step explanation:
Given:
Volume of a cylinder is [tex]64\pi\,\,cm^3[/tex]
To find: Dimensions of a cylinder
Solution:
Let [tex]r,h[/tex] denote height of a cylinder.
Volume of a cylinder = [tex]\pi r^2h[/tex]
Therefore,
[tex]64\pi=\pi r^2h\\64=r^2h\\4^2\,4=r^2h[/tex]
One possible dimension can be [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex].
Also, [tex]64=r^2h[/tex] can be written as [tex]16(2^2)=hr^2[/tex]
So, another possible dimension can be [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]
