Answer:
The correct answer is x = -92/9 or x = -10.2
Step-by-step explanation:
(The error is that the student didn't multiply 8 inside the parenthesis )
Steps to show work:
3/4x + 8 = 1/3
9x + 96 = 4 ➙ 9x = 4 - 96
9x = -92
x = -10.2 or -92/9
Answer to 32:
You need to find a common denominator and then multiply both sides of the equation by that number. You can do practically anything you want one side of the equation, as long as you do it to the other side as well.

Today, everything at a store is on sale. The store offers a 20% discount.
c. The discounted price of a hat is $18. What is the regular price?
(*Hint* What is your 100%?)
Answer:
Getting through ratio method
100-20=80 percent have to pay
18:80
x:100
cross multiply
80 x x=18 x 100
80x=1800
x=1800/80
x=22.5
So the original price was $22.50

The lines (m-2)x+y=2 and mx+2y=k intersect at (2,8). Find the values of m and k
Step-by-step explanation:
(m - 2)x + y = 2
y = -(m - 2)x + 2
8 = -(m - 2)(2) + 2
6 = -(m - 2)(2)
3 = -(m - 2)
-3 = m - 2
-1 = m
mx + 2y = k
2y = -mx + k
[tex]y = - \frac{1}{2} mx + \frac{k}{2} \\ y = \frac{1}{2} x + \frac{k}{2} \\ 8 = \frac{1}{2} (2) + \frac{k}{2} \\ 7 = \frac{k}{2} \\ 14 = k[/tex]

A man is twice as old as his son. Twelve years ago, the man
was 3 times as old as his son. How old are the father and son
today?
Answer:
Son's age = 24 years
Man's age = 48 years
Step-by-step explanation:
Let's take the age of son as x
Man's age = 2x
Twelve years ago,
Son's age= x-12
Man's age= 2x-12
Man is three times as old as his son so,
[tex] \frac{2x - 12}{x - 12 } = \frac{3}{1} [/tex]
Solving for x,
2x-12(1) = x-12(3)
2x-12 = 3x-36
2x-3x = -36+12
-x = - 24
x = 24
So if we substitute the values we get,
Son's age = 24 years
Man's age = 48 years
Hope you understand :)
Step-by-step explanation:
[tex] \underline{ \underline{ \text{Solution}}} : [/tex]
Let the present age of father be ' x ' years and that of the son be ' y ' years. From the first condition ,
x = 2y ••••••• equation ( i )From the second condition ,
x - 12 = 3 ( y - 12 ) ••••• equation ( ii )Substituting the value of x from equation ( i ) in equation ( ii ) :
[tex] \sf{2y - 12 = 3(y - 12)}[/tex]
Solve for y ( age of the son ) :
⟿ [tex] \sf{2y - 12 = 3y - 36}[/tex]
⟿ [tex] \sf{2y - 3y = - 36 + 12}[/tex]
⟿ [tex] \sf{ - y = - 24}[/tex]
⟿ [tex] \sf{y = 24}[/tex]
Now , Substituting the value of y in equation ( i ) , we get :
[tex] \sf{x = 2 \times 24}[/tex]
⟿ [tex] \sf{x = 48}[/tex]
So, the present age of the father is 48 years and that of the son is 24 years.

a confectioner mixes forty liters of 60% sugar syrup with a 10% sugar syrup to make a 20% sugar syrup. how much of the 10% syrup should she use?
Answer:
160 liters
Step-by-step explanation:
"a confectioner mixes forty liters of 60%":
Equation: 40 * .60
ow plug it in
0.60*40 + 0.10x = 0.20(40+x)
"how much of the 10% syrup should she use?":
.10x
"...to make a 20% sugar syrup.":
0.20(40+x)
Now that I have split the question into equations, let's put them together:
0.60*40 + 0.10x = 0.20(40+x)
Solve:
60*40 + 10x = 20*40 + 20x
10x = 40*40
x = 160 liters (amt of 10% solution needed)
Hope this helps :)
160 liters of 10% syrup is needed to make the mixture.
EquationAn equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the amount of 10% syrup. Hence:
(60% of 40) + (x of 10%) = (x + 40) of 20%
0.6 * 40 + x * 0.1 = (x + 40) * 0.2
24 + 0.1x = 0.2x + 8
x = 160 liters
160 liters of 10% syrup is needed to make the mixture.

8x = 80
X= 10
Which property is used in the last step to find that X= 10?
O distributive property
O addition property of equality
O subtraction property of equality
O division property of equality
Answer:
division property of equality
Step-by-step explanation:
Consider the equation and its solution.
In the first step, 8 is distributed inside the parenthesis. So distributive property is used.
In the second step, 16 is added on both sides. So addition property is used.
In the last step , 8 is divided on both sides. So, division property of equality is used.
Step-by-step explanation:
Answer:

Sebastian invested $7,100 in an account paying an interest rate of 8 1 4 \% compounded monthly. Eva invested $7,100 in an account paying an interest rate of 8 1 2 \% compounded continuously After 5 years, how much more money would Eva have in her account than Sebastian, to the nearest dollar?
Answer:
Given:
Sebastian :
Principal(invested)= $7,100
Rate of interest= 8.14% compounded monthly
Eva:
Principal(invested)= $7,100
Rate of interest= 8.12% compounded continuously
Step-by-step explanation:
After 5 years,
In Sebastian case:
Amount= Principal*[tex](1+R/100)^{t}[/tex]
Amount = 7100*[tex](1+8.14/100)^{12*5}[/tex]
Amount= 7100*[tex]1.0814^{60}[/tex]
Amount=7100*109.4415
Amount= $777,034.43
In Eva case,
Amount= Principal*[tex]e^{Rt/100}[/tex]
Amount = 7100*[tex]e^{0.0812*12*5\\}[/tex]
Amount= 7100*130.5818
Amount= $927,130.92
Difference between their money=$927,130.92-777034.43

The value of car after it is purchased depreciates according to the formula Vn=250000.85n, where V(n) is the car’ value in the nth year after it was purchased.
What is the purchased price of the car?
What is the annual rate of depreciation?
How much value does it lose in its fifth year?
After how many years will the value of the car be half of the original purchased price?
Answer:
25000
0.15
−1957.523
Step-by-step explanation:
Given the function :
Vn=250000.85n
Value of car due to Depreciation,
V(n) value of car after n years.
Initial value of car ; value of car at year 0
V(0) = Vn=25000(0.85)^(0)
V(0) = 25000(0.85)^0
V(0) = 25000(1)
V(0) = 25000
The Decay rate = annual Depreciation
According the exponential function.
mb^n
m = initial value
b = 1 - Decay rate
Relating to the equation given :
b = 0.85
0.85 = 1 - Decay rate
Decay rate = 1 - 0.85
Decay rate = 0.15
Value lost in fifth year : V(5) - V(4)
n = 5
V(5) = 25000(0.85)^5
V(5) = 25000 * 0.4437053125
V(5) = 11092.6328125
V(4) = 25000(0.85)^4 = 13050.15625
11092.6328125 - 13050.15625
= −1957.523
He total amount of fencing they need can be written as 5 x + 10. If x = 5; The family needs 160 yards of fencing for their home. The family needs 40 yards of fencing for their pool.
The question is incomplete. Here is the complete question.
A family needs to build a fence around their rectangular home and square pool, depicted below. A rectangle labeled home has its right side (2 + 5x) yards and its bottom side labeled (3 + 10x)yards. The square, labeled pool, is smaller than the rectangle. One of its side is labeled (2x)yards. The total amount of fencing they need can be written as x + 10. If x = 5:
The family needs _____ yards of fencing for their home.
The family needs _____ yards of fencing for their pool.
Answer: 160 yards
40 yards
Step-by-step explanation: Perimeter is the sum of every side of a polygon.
Rectangle and Square are quadrilateral, i.e., have 4 sides each, but in a rectangle, the 2 parallel sides are equal, while in a square, 4 sides are equal.
To determine the amount of yards to fence a rectangle home:
P = 2l + 2w
where
l is length (in this case, bottom side)
w is width (right side)
P is perimeter
P = 2(2 + 5x) + 2(3 + 10x)
P = 4 + 10x + 6 + 20x
P = 10 + 30x
As x = 5:
P = 10 + 30(5)
P = 160
The family will need 160 yards of fencing for their home.
For the square pool:
P = 4s
with s representing a side of the square
P = 4(2x)
P = 8x
As x = 5:
P = 8(5)
P = 40
The family needs 40 yards of fencing for their pool.
