Answer:
The hike is 4.5 miles
Step-by-step explanation:
We divided 3 by 2 since 3 is 2/3 done
3 ÷ 2 = 1.5
So now we know what 1/3 is; 1.5
So now we multiply 1.5 by 3
1.5 × 3 = 4.5
Thus, the hike is 4.5 miles long

Step-by-step explanation:
Let the cost of one t-shirt = t
And the cost of one sweatshirt = s
Since, Jayden sells 9 t-shirts and 3 sweatshirts for $420,
9t + 3s = 420
3t + s = 140 --------(1)
And Carson sells 1 t-shirt and 6 sweatshirts for $296,
t + 6s = 296 ----------(2)
Equation (1) multiplied by 6 then subtracted from equation (2)
(t + 6s) - 6(3t + s) = 296 - 6(140)
(t - 18t) + (6s - 6s) = 296 - 840
-17t = -544
t = $32
From equation (1),
3(32) + s = 140
s = 140 - 96
s = $44
This solution shows that cost one t-shirt is same for both sellers Carson and Jayden.

Answer:
k = 54/79
Step-by-step explanation:
You can eliminate fractions by multiplying both sides by 12.
15(2 -k) = 24(3k -1) -8k
30 -15k = 72k -24 -8k
54 = 79k
54/79 = k

The solution of (10 x/6)(10 x/8) = 1010 is
Answers
The solution to the exponential expression is given as follows:
x = 34.29.
How to solve the exponential expression?
The exponential expression for this problem is defined as follows:
[tex]10^{\frac{x}{6}} \times 10^{\frac{x}{8}} = 10^{10}[/tex]
When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.
The sum of the exponents is given as follows:
x/6 + x/8 = 4x/24 + 3x/24 = 7x/24.
Hence the equivalent expression is given as follows:
[tex]10^{\frac{7x}{24}} = 10^{10}[/tex]
The function 10^x is an injective function, hence the value of x is obtained as follows:
7x/24 = 10
7x = 240
x = 240/7
x = 34.29.

Collin Buys a TV for £720 depreciate at a rate of 4% per year how much will it be worth in three years
Answers
Answer:
The worth of the TV after 3 years is £809.90208
Step-by-step explanation:
The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine
The given parameters of the TV are;
The amount at which Collin buys the TV, P = £720
The rate at which the TV depreciates at, R = 4%
The number of years the depreciation is applied, T = 3 years
The amount the TV is worth after three years, 'A', is given as follows;
[tex]A = P \cdot \left(1 + \dfrac{R}{100} \right )^T[/tex]
By plugging in the known values, we have;
[tex]A = 720 \cdot \left(1 + \dfrac{4}{100} \right )^3 = 809.90208[/tex]
The amount the TV is worth after three years, A = £809.90208

How to calculate the surface area of a composite figure?Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]
That ∑ sign shows "sum"
We are given that;
The side of two hexagon is 2ft, painting measures 9*25ft.
Now,
In this case, s = 2 feet. Therefore, the area of one hexagonal window is:
Area = (3√3 × 2²)/2 Area = (12√3)/2 Area ≈ 10.39 square feet
Since there are two windows, we need to multiply this by 2 and subtract it from the total area of the wall:
225 - (2 × 10.39) ≈ 204.22 square feet
This is the area that needs to be painted. To find how much Deb will have to spend, we multiply this by $1.75 per square foot:
204.22 × $1.75 ≈ $357.39
Rounding this to the nearest dollar, we get:
$357
Therefore, by the area of painting the answer will be $357.

Answers
Answer:
3x + 2
Step-by-step explanation:
The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?
The shape of a poster = Rectangular shape
Hence:
The Perimeter of a Rectangle (Poster) = 2L + 2W
Where:
Length = Height = 7x + 10
Perimeter = 20x + 24
Therefore:
20x + 24 = 2(7x + 10) + 2W
20x + 24 = 14x + 20 + 2W
2W = 20x + 24 - (14x + 20)
2W = 20x + 24 -14x - 20
2W = 6x + 4
W = (6x + 4)/2
W = 3x + 2
Therefore, the width of the poster
= 3x + 2
