Answer:83÷3=27.6 or 27.667

Step-by-step explanation:

The number 83 divided by 3 equals 27 remainder 2.

The long division refers to the mathematical method for dividing large numbers into multiple smaller groups or parts. The number which we divide into small groups is called the dividend, the number by which we divide is called the divisor.

Answer:

x=5

Step-by-step explanation:

we have

[tex]3(x+2)+x=2x+16[/tex]

Solve for x

Distribute left side

[tex]3x+6+x=2x+16[/tex]

Combine like terms left side

[tex]4x+6=2x+16[/tex]

Group terms that contain the same variable

[tex]4x-2x=16-6\\2x=10\\x=5[/tex]

therefore

For x=5

The equation is true

Verify

substitute the value of x=5 in the original expression and evaluate

[tex]3(5+2)+5=2(5)+16[/tex]

[tex]3(7)+5=10+16[/tex]

Answer:  [tex]average\ rate\ of\ change\approx-3[/tex]

Step-by-step explanation:

For this exercise you need to use the following formula:

[tex]average\ rate\ of\ change=\frac{f(b)-f(a)}{b-a}[/tex]

You need to find the average rate of change of the given function g(x) over the following interval:

 [tex][-1,2][/tex]

So, you can see in the table that the point whose x-coordinate is -1, is:

[tex](-1,5)[/tex]

And the point whose x-coordinate is 2, is:

[tex](2,-3)[/tex]

Knowing this, let be:

[tex]a=-1\\f(a)=5\\\\b=2\\f(b)=-3[/tex]

Now you can substitute values into the formula:

[tex]average\ rate\ of\ change=\frac{-3-5}{2-(-1)}[/tex]

Finally, evaluating, you get that the average rate of change over the interval indicated in the exercise, is:

[tex]average\ rate\ of\ change=\frac{-8}{3}\\\\average\ rate\ of\ change=-2.66\\\\average\ rate\ of\ change\approx-3[/tex]

Step-by-step explanation:

The expression for the total number of miles she drove in two weeks is 254 + c miles

Solution:

Given that,

Last week katlin drove 254 miles

This week she drove c miles

To find: Expression for the total number of miles she drove in two weeks

From given,

Last week = 254 miles

This week = c miles

Therefore,

Total miles in two weeks = last week + this week

Total miles in two weeks = 254 + c

Thus the expression for the total number of miles she drove in two weeks is 254 + c miles

Option D: A(n) = a + (n – 1) d

Solution:

To identify the formula for finding the nth term of an arithmetic sequence.

Let a be the first term.

d be the common difference of the each term.

n be the term of the number.

A(n) be the nth term of the arithmetic sequence.

Arithmetic formula:

A(n) = a + (n – 1) d

Example: 1, 4, 7, 10, 13, 16, 19, ...

This is a arithmetic sequence.

a = 1, d = 4 – 1 = 3.

To find the 5th term:

Substitute this in the above formula, we get

A(n) = a + (n – 1) d

A(5) = 1 + (5 – 1) 3

       = 1 + 4(3)

       = 1 + 12

A(5) = 13

In the given sequence 5th term is 13.

Hence Option D is the correct answer.

A(n) = a + (n – 1) d

Answer:

A(n) = a + (n - 1)d

Step-by-step explanation:

pretend there is a 1 in front of the h making it -1h and divide it by 14(ignoring the h), making the 14 a negative

Answer: it is -14 instead of regular 14, because a positive and a negative make a negative. A negative negative make a positive, and so on.

To solve the system of equations using substitution, Fina needs to isolate one variable and substitute it into the other equation. The solution to the system of equations is x = -3 and y = -9.

To solve this system of equations using substitution, Fina needs to isolate one variable in one of the equations and then substitute that expression into the other equation.

Here are the steps:

Choose one equation and isolate one variable. Let's isolate x in the first equation: 2x - y = 3. Add y to both sides: 2x = y + 3 and divide by 2: x = (y + 3)/2.

Substitute the expression for x in the other equation. Replace x in the second equation with (y + 3)/2: -1.5((y + 3)/2) + 3y = -18.

Solve the equation for y. Simplify the equation: -1.5y - 4.5 + 3y = -18. Combine like terms: 1.5y - 4.5 = -18. Add 4.5 to both sides: 1.5y = -13.5. Divide by 1.5: y = -9.

Substitute the value of y back into the expression for x to find its value. Replace y in x = (y + 3)/2 with -9: x = (-9 + 3)/2 = -6/2 = -3.

Therefore, the solution to the system of equations is x = -3 and y = -9.

Answer:

[tex]m=-\frac{39}{80}[/tex]

Step-by-step explanation:

we have

[tex]\frac{2}{5}=2m+\frac{11}{8}[/tex]

Solve for m

That means ----> Isolate the variable m

Multiply both sides by 40 to remove the fractions

Note: 40=(8)(5)

[tex](40)\frac{2}{5}=(40)2m+(40)\frac{11}{8}[/tex]

[tex]16=80m+55[/tex]

subtract 55 both sides

[tex]16-55=80m\\-39=80m[/tex]

Divided by 80 both sides

[tex]m=-\frac{39}{80}[/tex]

Final answer:

To find the height of the tree in yards, divide the height in feet by 3, the conversion factor from feet to yards.

Explanation:

The Redwood National Park is home to some of the largest trees in the world, including Hyperion, the tallest tree in the park at approximately 379 feet. To find the height of the tree in yards, we can convert the height from feet to yards by using the conversion factor of 1 yard = 3 feet.

Height in yards = Height in feet / Conversion factor

Height in yards = 379 feet / 3 feet/yard

Height in yards = 126.33 yards

Therefore, the height of Hyperion is approximately 126.33 yards.

We need to find the surface area for this entire figure!

We can see that this is a pyramid here - we must find the area of the 3 triangles and the base triangle at the bottom.

The 3 triangles building up the pyramid are all equal to each other.

To find the area of a triangle, use  [tex]Area = base*height/2[/tex]

[tex]Area=3(\frac{5*7}{3} )+(\frac{5*4.3}{2})\\Area=35+10.75=45.75[/tex]

Step-by-step explanation:

Answer:

n = 450

Step-by-step explanation:

18%·n = 81

18·n/100 = 81

18n = 8100

n = 8100 : 18

n = 450

Answer:

81 is 18% of 450.

Step-by-step explanation:

81 ÷ 18 = 4.5

4.5 x 100 = 450

450 - 18% = 369

450 - 369 = 81

So, 18% of 450 is 81 and 81 is 18% of 450.

Step-by-step explanation:

To find the number of blue fish, we set up an equation based on the given information, solving which indicates there are 18 blue fish in the tank (option A).

The question is a word problem asking to find out the number of blue fish in a tank given the total number of fish and the relationships between the counts of different colored fish. We can set up algebraic expressions to solve for the number of blue fish. Let the number of blue fish be represented by x. According to the problem, there are six more yellow fish than blue, which we can express as x + 6. There are four fewer black fish than blue, which we can say is x - 4. The total number of fish is given as 56.

So, the equation we can set up is:

x + (x + 6) + (x - 4) = 56

Simplifying the equation, we get:

3x + 2 = 56

Solving for x, we subtract 2 from both sides to get:

3x = 54

And then divide by 3:

x = 18

Thus, there are 18 blue fish in the tank, which corresponds to option A.

The cost of each ribeye steak dinner is $ 29 and cost of each grilled salmon dinner is $ 20

Solution:

Let "a" be the cost of each ribeye steak dinners

Let "b" be the cost of each grilled salmon dinners

A waitress sold 11 ribeye steak dinners and 12 grilled salmon​ dinners, totaling ​$560.63 on a particular day

Thus we frame a equation as:

11 x cost of each ribeye steak dinners + 12 x cost of each grilled salmon dinners = 560.63

[tex]11 \times a + 12 \times b = 560.63[/tex]

11a + 12b = 560.63 -------- eqn 1

Another day she sold 16 ribeye steak dinners and 6 grilled salmon​ dinners, totaling ​$584.46

Thus we frame a equation as:

16 x cost of each ribeye steak dinners + 6 x cost of each grilled salmon dinners = 584.46

[tex]16 \times a + 6 \times b = 584.46[/tex]

16a + 6b = 584.46 ------------ eqn 2

Let us solve eqn 1 and eqn 2

Multiply eqn 2 by 2

32a + 12b = 1168.92 ------- eqn 3

Subtract eqn 1 from eqn 3

32a + 12b = 1168.92

11a + 12b = 560.63

( - ) ----------------

21a = 1168.92 - 560.63

21a = 608.29

Divide both sides by 21

[tex]a = 28.96 \approx 29[/tex]

Substitute a = 29 in eqn 1

11(29) + 12b = 560.63

319 + 12b = 560.63

12b = 560.63 - 319

12b = 214.63

Divide both sides by 12

[tex]b = 20.13 \approx 20[/tex]

Thus cost of each ribeye steak dinner is $ 29 and cost of each grilled salmon dinner is $ 20

Answer:

A. Only Khaled

Step-by-step explanation:

The teachers equation is:

[tex]-10x-7y=5[/tex]

[tex]12x-8y=-4[/tex]

If a row operation on the teacher's equation results in any of the system of the students' equation then the two systems are equivalent and will have the same solution.

For instance:

Let's maintain the bottom equation and add both equation to replace the top equation:

[tex]-10x+12x-7y-8y=5+-4\\12x-8y=-4[/tex]

This results in Khaled's equation:

[tex]2x-15y=1\\12x-8y=-4[/tex]

On the other hand we cannot perform a row operation to obtain Miku's equation
