Answer:
$30.60
Step-by-step explanation:
What we know:
The bill for Mr. Wilson's diner meal is $25.50.
He gives a 20% tip to the waiter.
To figure out this tip, multiply 1/5 by 25.5.
1/5 * 51/2
51/10 = $5.10 tip.
Here, it's asking for the total, including the $5.10 tip. So, add $5.10 to $25.50 for $30.60 total, including the tip.
(For a simpler method *multiply 6/5 by $25.5)

solve by the matrix method , x+y/5 -1=y-x
10x - 4y = 5 (if it requires shorten)
Step-by-step explanation:
x + y/5 - 1 = y - x
<=> (5x + y - 1.5)/5 = 5(y - x)/5
<=> 5x + y - 5 = 5y - 5x
<=> 5x + 5x + y - 5y = 5
<=> 10x - 4y = 5
The bakers at Healthy Bakery can make 170 bagels in 2 hours. How many
bagels can they bake in 14 hours? What was that rate per hour?
Given:
The bakers at Healthy Bakery can make 170 bagels in 2 hours.
To find:
How many bagels can they bake in 14 hours and the rate per hour.
Solution:
We have,
Number of bagels the bakers can bake in 2 hours = 170 bagels
Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels
= 85 bagels
Therefore, the average rate is 85 bagels per hour.
Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels
= 1190 bagels
Therefore, the bakers can bake 1190 bagels in 14 hours.

find the value of x
a. 68
b. 44
c. 56
d. 22
Answer: x=68° because this triangle is a isoscele triangle which means that it haves 2 sides that are congruent and equivalent which means they have the same value and sides and are Congruent just means In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
The value of angle [x] is equivalent to 44°.
What is Parallelogram? What is triangle? What is a expression? What is a mathematical equation?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.We have a triangle as shown.
We know, the angles opposite to equal sides are equal.
So, we can write -
x + 68° + 68° = 180°
x = 180° - (136°)
x = 44°
Therefore, the value of angle [x] is equivalent to 44°.

A clothing store buys jeans for $12 and marks them up 200% before selling them to customers. What is the selling price of the jeans? Group of answer choices
Answer:
The selling price = $36
Step-by-step explanation:
The Buying price or Cost (C) = $12Markup = 200%So
Percent Markup on Cost (M) = 200% of 12
= 200/100 × 12
= 2 × 12
= $24
Thus the selling price = Cost (C) + Markup (M)
= $12 + $24
= $36
Therefore, we conclude that:
The selling price = $36

How many years will it take an initial investment of $25,000 to triple to $75,000 at an annual rate of 7% compounded continuously
Answer:
[tex]t = 15.7[/tex]
Step-by-step explanation:
Given
[tex]Principal = 25000[/tex] --- P
[tex]Amount = 75000[/tex] --- A
[tex]Rate = 7\%[/tex] --- R
Required
Determine the time (t)
Using continuous growth formula:
We have
[tex]A = Pe^{rt}[/tex]
Convert rate to decimal
[tex]Rate = 7\%[/tex]
[tex]r = 0.07[/tex]
Substitute values for A, P and r
[tex]75000 = 25000 * e^{0.07t}[/tex]
Divide both sides by 25000
[tex]3 = e^{0.07t}[/tex]
Rewrite the exponential function as logarithmic, we have:
[tex]ln3 = 0.07t[/tex]
Reorder
[tex]0.07t = ln3[/tex]
Divide both sides by 0.07
[tex]t = \frac{ln3}{0.07}[/tex]
[tex]t = \frac{1.09861228867}{0.07}[/tex]
[tex]t = 15.69[/tex]
[tex]t = 15.7[/tex]
Hence, the time is approximately 15.7 years

Solution:
We know that, in the expansion of [tex](x+y)^n[/tex],
[tex]T_{r+1}=^nC_rx^{n-r}y^r[/tex] ...(i)
[tex](3x-2)^9[/tex] has only one x and in [tex]x^6[/tex], the power of x is 6. It is possible if
[tex]n-r=6[/tex]
[tex]9-r=6[/tex]
[tex]9-6=r[/tex]
[tex]3=r[/tex]
Putting n=9, r=3, x=3x and y=-2 in (i), we get

[tex]T_{4}=\dfrac{9!}{3!(9-3)!}\times (3x)^{6}(-8)[/tex]

Use the distributive property to write an expression that is equivalent to:
3(x + 5)
Answer: 3x + 15
Step-by-step explanation:
In order to use the distributive property, you simply multiply the number on the outside by both the number inside the parenthesis
So, in this case, we would multiply 3 by X and 3 by 5
3 times x = 3x
3 times 5 =15
Your new equation is then made by adding these two together
3x+15
Answer 3x + 15
