Answer:
-1
Step-by-step explanation:
Let's assume 100 as the number. 80% of that number is 80. That's A. And since 80 is two-thirds of that number, the second number has to be 120. Simplifying that would give 5/6. 5-6 = -1
Answer: 1:1.2
1-1.2= -0.2
Step-by-step explanation:
x = first number
y = second number
80/100*x (80 percent of one number)
2/3*y (two thirds of the second number)
equating
80/100*x=2/3*y
= 1.2=y
substituting:
80/100*x = 2/3 * 1.2
= x=1
substituting the value of x in the original equation
80/100 * 1 = 2/3 * y
= y=1.2
so, x=1, y=1.2
x:y
=1:1.2
x-y= 1 - 1.2 = -0.2

What is mean by Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
g (x) is the indicated transformation of f (x).
The rule of f (x) is,
f (x) = - x + 5 ; horizontally translation 2 units left.
Now,
The rule of f (x) is,
f (x) = - x + 5 ; horizontally translation 2 units left.
Since, g (x) is the indicated transformation of f (x).
So, g (x) = f (x + 2)
Hence, We get;
g (x) = - (x + 2) + 5
= - x - 2 + 5
= - x + 3
Thus, The rule of the function g (x) will be;
⇒ g (x) = - x + 3

Consider a car with a cash price of $4,000, offered on the installment plan for $146 per month for 36 months.
Calculate (a) the total installment price, (b) the carrying charges, and (c) the number of months needed to save the money at the monthly rate to buy the car for its cash price.
Use commas and decimal points in your answers when appropriate. Round to two decimal places if necessary
(a) The total installment price is $5256 .
(b) The carrying charges is $1256 .
(c) The number of months needed to save the money at the monthly rate to buy the car for its cash price is 28 months .
In the question,
it is given that
Price of the car in cash = $4000
amount to be paid as installment per month = $146
time for installment = 36 months
Part(a)
the total installment price can be calculated using the formula
total price = (per month installment) * (number of months)
Substituting the values , we get
total price = 146*36
= 5256
So , total installment price = $5256
Part(b)
the carrying charges can be calculates using the formula
carrying charges = total installment price - price in cash
Substituting the values ,we get
carrying charges = 5256-4000
= 1256
So, carrying charges = $1256
Part(c)
the number of months needed to save the money at the monthly rate to buy the car for its cash price , can be calculated using the formula .
number of months = (price in cash)/(monthly rate)
= 4000/146
= 27.39
rounding , we get
≈ 28
number of months = 28 months
Therefore , (a) The total installment price is $5256 .
(b) The carrying charges is $1256 .
(c) The number of months needed to save the money at the monthly rate to buy the car for its cash price is 28 months .

Question 5. Solve for X. Can someone help me I don’t know how to solve this one
Answer:
x = 7
Step-by-step explanation:
since 2 sides are congruent, then the triangle is isosceles with base angles being congruent , both (9x - 25)
the sum of the 3 angles in the triangle = 180° , that is
9x - 25 + 9x - 25 + 104 = 180
18x + 54 = 180 ( subtract 54 from both sides )
18x = 126 ( divide both sides by 18 )
x = 7
200 college freshmen were interviewed, 95 were registered for a math class, 80 were registered for an english class, and 60 were registered for both math and english how many signed up neither for math nor english?
Total number of college freshmen that signed up neither math nor English is 85
Total number of college freshmen interviewed = 200
Number of college freshmen registered for a Math class = 95
Number of college freshmen registered for a English class = 80
Number of college freshmen registered for both math and English = 60
Total number of college freshmen signed up either for math or English = Number of college freshmen registered for a Math class + Number of college freshmen registered for a English class - Number of college freshmen registered for both math and English
Total number of college freshmen signed up either for math or English = (95 + 80 - 60) = 115
Total number of college freshmen signed up neither math nor English = ( Total number of college freshmen interviewed - Total number of college freshmen signed up either for math or English )
Total number of college freshmen signed up neither math nor English = 200 -115 = 85
Thus, 85 college freshmen signed up neither math nor English.

for each linear equation in the table, indicate weather the equation has no solution, one solution, or infinitely many solutions x-3=x+3-4x-8=4x+8
Given:
• x - 3 = x + 3
Let's solve the equation above
x - 3 = x + 3
x - x = 3 + 3
0 = 6
Therefore, since 0 = 6, we can say the equation has no solution.
Equation 2:
-4x - 8 = 4x + 8
Let's solve the equation.
-4x - 4x = 8 + 8
-8x = 16
Divide both sides by -8:
[tex]\begin{gathered} \frac{-8x}{8}=\frac{16}{-8} \\ \\ x=-2 \end{gathered}[/tex]Since x = -2, we can say the equation has one solution

One number is 4 more than 2 times another. Their product is 30. Find the numbers. The numbers are ? and ? or ?and ? .
Let the first number be x and y be the second.
Then we habe:
I) x - 4 = 2y
II) x*y = 30
We can rewrite equation I as:
x = 2y + 4
Applying this result on equation II, we have:
(2y + 4)*y = 30
2y² + 4y = 30
2y² + 4y - 30 = 0
y² + 2y - 15 = 0
[tex]\begin{gathered} y_+=\frac{2+\sqrt[]{(2)^2-4\cdot1\cdot(-15)}}{2} \\ y_+=\frac{2+\sqrt[]{64}}{2} \\ y_+=\frac{10}{2} \\ y_+=5 \end{gathered}[/tex]The second root is negative and don't satisfy equations I and II, then we can discard it.
Replacing y with 5 in equation I, we have:
x - 4 = 2*5
x = 2*5 + 4
x = 14

Which ordered pairs in the form (x, y) are solutions to the equation 7x-5x=28
The ordered pairs A. (−6, −14) and B. (−1, −7) in the form (x, y) are solutions to the equation 7x-5x=28.
What is ordered pairs?A pair is considered to be ordered when two elements are written inside parantheses and are separated by a comma. The ordered pair (x, y), for instance, is represented by the notation (x, y), where 'x' is referred to as the first element and 'y' as the second element.
Depending on the context in which they are used, these elements—which can either be variables or constants—have different names. In a pair of elements that are ordered, the elements' order is somewhat significant. This indicates that (x, y) might not always be equal to (y, x).
We have given the equation 7x – 5y = 28
we know that a ordered pair (x,y) must satisfy the equation
So let us do trial and error method
A. (−6, −14)
7(-6) – 5(-14) = 28
-42 + 70 = 28
28 = 28
ordered pair (−6, −14) in the form (x, y) satisfy for 7x – 5y = 28
B. (−1, −7)
7(-1) – 5(-7) = 28
-7 + 35 = 28
28 = 28
ordered pair (−1, −7) in the form (x, y) satisfy for 7x – 5y = 28
C. (4, 10)
7(4) – 5(10) = 28
28 - 50= 28
22 ≠ 28
ordered pair (4, 10) in the form (x, y) doesn't satisfy for 7x – 5y = 28
D. (7, 9)
7(7) – 5(9) = 28
49 - 45= 28
4 ≠ 28
ordered pair (7, 9) in the form (x, y) doesn't satisfy for 7x – 5y = 28

The height of building ramp is h = 2 foot.
The base of the building ramp is b = 4 foot.
The code for new bulding is,
[tex]\begin{gathered} \frac{h}{b}=\frac{1}{4} \\ h=\frac{b}{4} \end{gathered}[/tex]Let the new base be x for new building code and height remain same h = 2.
