Answer:
+25;+18;-10
Step-by-step explanation:
Ok so let's break down the scenario step by step:
His uncle gave him $25 so that means it's positive so +25 Now he earned $18 so that means it is also positive so +18And now he spent $10 which means it is negative so - 10(And of you want to find out the amount left with him,
(25+18)-10
=43-10
=$33)

Given:
The area of a rectangle is 99 square yd.
Length of the rectangle = 7 yd more than twice the width.
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then, length of the rectangle is:
[tex]Length=2x+7[/tex]
Area of a rectangle is:
[tex]A=length\times width[/tex]
[tex]A=(2x+7)\times x[/tex]
[tex]A=2x^2+7x[/tex]
The area of a rectangle is 99 square yd.
[tex]2x^2+7x=99[/tex]
[tex]2x^2+7x-99=0[/tex]
Splitting the middle term, we get
[tex]2x^2+18x-11x-99=0[/tex]
[tex]2x(x+9)-11(x-9)=0[/tex]
[tex](x+9)(2x-11)=0[/tex]
Using zero product property, we get
[tex](x+9)=0[/tex] and [tex](2x-11)=0[/tex]
[tex]x=-9[/tex] and [tex]x=\dfrac{11}{2}[/tex]
[tex]x=-9[/tex] and [tex]x=5.5[/tex]
Width of the rectangle cannot be negative. So, [tex]x=5.5[/tex] yd.
Now, the length of the rectangle is:
[tex]Length=2x+7[/tex]
[tex]Length=2(5.5)+7[/tex]
[tex]Length=11+7[/tex]
[tex]Length=18[/tex]
Therefore, the length of the rectangle is 18 yd and the width of the rectangle is 5.5 yd.

At a hockey game, a vender sold a combined total of 136 sedas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the
number of sodas and the number of hot dogs sold
Answer: just do 3x136
step-by-step explanation:
bfui3qtwsd3wa CAF
The number of sodas sold is 102 and the number of Hot dogs sold is 34.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, At a hockey game, a vendor sold a combined total of 136 sodas and hot dogs.
Let "x" be the number of hot dogs sold
Since The number of sodas sold was three times the number of hot dogs sold.
thus,
Number of Sodas sold = 3 * x
Since total items sold = 136
x + 3x = 136
4x = 136
x = 34
Thus, the number of Sodas sold = 34 * 3
the Number of Sodas sold = 102
therefore, the number of sodas sold is 102 and the number of Hot dogs sold is 34.

A real estate agent earns 3% commission on each house she sells. If she sells a 150,000 house, how much commission will she get?
Answer:
4,500
Step-by-step explanation:
150,000x.03=4500
The commission of the real estate agent is 4500 which is 3% of 150,000.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A real estate agent earns a 3% commission on each house she sells and she sells a 150,000 house.
So, His commission is 3% of 150,000.
Therefore,
Commission = (3/100)×150000.
Commission = 4500.

The graph shows the function f(x) = 6(3)^x What is the value of the inverse function, f ^-1 at x = 2
Answer:
Step-by-step explanation:
y = f(x)
y = 6 * 3^x
Interchange x and y
x = 6 * 3^y
Divide by 6
x/6 = 3^y
Take the log of both sides
log(x/6) = log(3)^y
Bring the y down
log(x/6) = y log(3) \
Divide by log(3)
log(x/6)/log(3) = y
Let x = 2
log(2/6) / log(3) = y
-(0.4771 )/ 0.4771 = y
y = - 1
Remark
The original graph is in green
The red graph is the inverse.
The point (2,-1) is marked so that you know it falls on the inverse.

Acabcompanycharges $ 4 percabride,plusanadditional $ 1 permiledriven.Howlongisacabridethatcosts $ 28 ?
Answer:
24 miles
Step-by-step explanation:
Given that the cost of the company consist of two elements; a fixed cost equivalent to $4 and a variable cost element which depends on the miles driven. If the car travels x miles then the cost will be
= 4 + 1*x
= 4 + x
If the total cost is $28 then
4 + x = 28
Subtract 4 from both sides
x = 28 - 4
= 24
The car ride is
24/1 = 24 miles

7. Is it proportional?
8. If so, what is the constant of
proportionality? (unit rate)
9. Write an equation that
expresses the table in the
form
Y= KX
Answer:
A unit rate is the rate of change in a relationship where the rate is per 1.
The rate of change is the ratio between the x and y (or input and output) values in a relationship. Another term for the rate of change for proportional relationships is the constant of proportionality.
If the rate of change is yx, then so is the constant of proportionality. To simplify things, we set yx=k, where k represents the constant of proportionality.
If you solve a yx=k equation for y, (like this: y=kx), it is called a direct variation equation. In a direct variation equation, y varies directly with x. When x increases or decreases, y also increases or decreases by the same proportion.
To find y in a direct variation equation, multiply x by the constant of proportionality, k.
For example: Given the relationship y=7x, the constant of proportionality k=7, so if x=3, then y=3×7 or 21.
Given the same relationship, if x=7, then y=7×7, or 49.
Step-by-step explanation:
Answer:
Yes it is. Y=2.5x
Step-by-step explanation:
So, lets start with bthe first values of the table and work our way down:
2x=5y
Lets just divide both sides by the 2:
x=5/2y
This means that for every 1 x, there should be 5/2y's.
Or, for every 1 x, there should be 2.5ys.
Lets check the next few to see if thats correct:
3x=7.5y
Divide both sides by 3:
x=7.5/3
This means for every one x, there are again, 2.5ys.
Lets check one more just to be sure:
4x=10y
Divide both sides by 4:
x=10/4
This means for everyone one x, y equals 2.5ys, yet again,
So we can conclude that the poprotional relationship between x and y is:
When x equals 1, y=2.5
Or
Y=2.5x

Identify the area of the trapezoid.
Answer:
A = 37.5
Step-by-step explanation:
The formula for finding the are of a trapezoid is (a + b)/2(h)
a = base
b = base
h = height
A = (6.1 + 8.9) / 2(5)
A = 37.5
Answer:
The answer is 37.5.
Step-by-step explanation:
The area for a triangle is A=1/2 bh.
In this case, we have 2 triangles, so we just make it one rectangle.
Each triangle is (1.4*5)/2. (1.4*5)*2/2=7.
You do 2/2 because the half and the two triangles cancel out.
6.1*5=30.5.
30.5+7=37.5

Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16. What steps will help show that circle A is similar to circle B?
Answer:
1) Use translation to coincide the center of a circle with the center of the other circle.
2) We construct the respective loci for the circles.
3) Compare each loci by direct inspection ([tex]f(x,y)[/tex] must be the same and radii must be different but constant) to conclude the similarity of the two circles.
Step-by-step explanation:
Geometrically speaking, a circle is formed after knowing its center and radius.
1) Use translation to coincide the center of a circle with the center of the other circle. In this case, we translate the center ([tex]C_{A} (x,y) = (6,7)[/tex]) of the circle A to the location of the center of the circle B ([tex]C_{B}(x,y) = (2,4)[/tex]):
[tex]C_{A'} (x,y) = (6,7) + [(2,4) - (6,7)][/tex]
[tex]C_{A'} (x,y) = (2,4)[/tex]
2) We construct the respective loci for the circles.
By Analytical Geometric, a circle is represented by the following locus:
[tex](x-h)^{2}+(y-k)^{2} = r^{2}[/tex]
Where:
[tex]x, y[/tex] - Coordinates of a point of the circunference.
[tex]h, k[/tex] - Coordinates of the center of the circle.
[tex]r[/tex] - Radius of the circle.
3) Compare each loci by direct inspection ([tex]f(x,y)[/tex] must be the same and radii must be different but constant) to conclude the similarity of the two circles.
Then, the circles A' and B are represented by the following loci:
Circle A'
[tex](x-2)^{2} + (y-4)^{2} = 16[/tex]
Circle B
[tex](x-2)^{2} + (y-4)^{2} = 256[/tex]
Since both the [tex]f(x,y)[/tex] component of each circle is the same and radii are different but constant, then we conclude that circle A is similar to circle B.
