I think it's either 21+4×6-1=9 or 2+6×8-6=7

Answer:

One solution

Step-by-step explanation:

Adding 3x to both sides results in   7 = 6x + 7, or 6x = 0.  There is one solution, and that solution is x = 0.

Answer: The number is 86.

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

"Six subtracted from a number ", a number means the variable (x), and six subtracted from a number is "x -6".

"The result is divided by 4", so (x-6) /4.

This result is added to then, so: 10+ (x-6) /4.

And finally, to give 30 means that all the expression equals to 30.

10+ (x-6) /4 = 30

Solving:

(X-6) /4 = 30 -10

(X-6) /4 = 20

X-6 = 20x4

X-6 = 80

x =80+6

x= 86

The number is 86.

Answer:

Prime: 9/25    Not Prime: 16/25

Step-by-step explanation:

In 1 - 25 there are 9 prime numbers, or numbers that cannot be divided by anything other than 1 or itself. They are  2 3 5 7 11 13 17 19 and 23,

Selecting a NON Prime: 25-9= 16 so we would put 16 over 25.

16/25 since it can not be reduced that is the fraction

Selecting a Prime: We know there is 9 prime numbers so we would put it over 25. 9/25 also cannot be reduced any further,

Answer: D)

Step-by-step explanation: this is because you find the area of the circle which is pi times radius squares. So the area of the circle is 16 pi. And the. You have to multiply by 7 because you are staking the circle 7 times. To get 122 pi which is the answer so the answer is D. :)

The value of the volume of the cylinder is,

V = 96π units³

A cylinder is a three-dimensional solid that maintains, at a given distance, two parallel bases connected by a curved surface. These bases often have a circular form (like a circle), and a line segment known as the axis connects the centres of the two bases.

We have to given that;

Radius of cylinder = 4 units

Height of cylinder = 6 units

Since, The value of volume of cylinder is,

⇒ V = πr²h

Hence. The value of the volume of the cylinder is,

V = π (4²) × 6

V = 16 × 6 π

V = 96π units³

Thus, The value of the volume of the cylinder is,

V = 96π units³

Answer:

20 bicycles and 10 tricycles.

Step-by-step explanation:

Let the number of bicycles and tricycles be x and y respectively.

Each vehicle has 1 seat.  Each bicycle 2 wheels and each tricycle 3 wheels.

Then we have the system of equations:

x + y = 30 ............ (1)

2x + 3y = 70.........(2)

Multiply the first equation by -2:

-2x - 2y = -60......(3)

Adding (2) + (3):

y = 10

Substituting for y in equation (1):

x + 10 = 30

x = 20.    

By simultaneous equation, there are a total of 20 bicycles and 10 tricycles.

Let the number of bicycles and tricycles be x and y respectively.

It is given that there is a total of 30 seats and 70 wheels.

Answer:

A = [tex]\frac{1}{2}[/tex]bh

Step-by-step explanation:

The area of a triangle is defined as half the product of its base by its height.

A = [tex]\frac{1}{2}[/tex]bh

If you do not know the height but you know the length of the three sides of the triangle you can use Heron's formula to find the area

If the lengths of the sides are a, b, c then the area is

[tex]A = \sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where

[tex]s =\frac{a+b+c}{2}[/tex]

You do length x width (for triangles its called base x height) and divide the product by 2

Step-by-step explanation:

2(4z -9 -7) = 166 -46

First combine like terms

2(4z -16) = 120

Divide each side by 2

2/2(4z -16) = 120/2

4z-16=60

Add 16 to each side

4z-16+16 = 60+16

4z = 76

Divide each side by 4

4z/4 = 76/4

z = 19

The center of the circle is (-7,13)

Answer:

6 runners

Step-by-step explanation:

Each runner ran 7.5 km.  If there were n runners, then (7.5 km)n = 45 km.

Solve this for n by dividing 7.5 km into 45 km:

n = 6

There were 6 runners.

The answer depends on which measure is the height and both bases.

Answer:

114 degrees

Step-by-step explanation:

The formula to find the measure of all angles in a regular polygon is [tex](n-2)180[/tex], where n = total number of sides.

Thus, we substitute n for 10, and you get:

[tex](10-2)180=1440[/tex]

If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.

A central angle in a regular ten-sided polygon would be 144 degrees.

Final answer:

The central angle of a regular polygon with 10 sides (a decagon) is calculated by dividing 360° by the number of sides, resulting in a central angle of 36°.

Explanation:

To find the measure of a central angle of a regular polygon with 10 sides (a decagon), we use the formula for the measure of each central angle:

Central Angle = 360° / Number of sides

Thus, the central angle of a regular decagon is:

360° / 10 = 36°

This is because the central angles are equally distributed around the center point, dividing the 360° of a circle evenly by the number of sides in the polygon.

Answer:

(-3,-2)

Step-by-step explanation:

y = -x - 5

y = 2x + 4

plug in one of the y equations

(2x+4)= -x - 5

2x+4=-x-5

3x=-9

x= -3

plug in x to one of the y equations

y= -(-3) -5

y=3-5

y= -2

x= -3, y= -2

sin x = 32/58

We need to find the angle x.

Take the sine inverse on both sides.

Let arcsin = sine inverse

arcsin(sin x) = arcsin(32/58)

x = 33.485376623

Rounding off to the nearest hundredth, we get x = 33.49°.

The equation 5(1 + 3) - 3(2 - 1) when solved gives the final result 17.

To evaluate the expression 5(1 + 3) - 3(2 - 1), you need to follow the proper order of operations, which consists of parentheses first, then multiplication or division (from left to right), and finally addition or subtraction (also from left to right).

First, simplify the expressions inside the parentheses:

Next, multiply each result by the number outside the parentheses:

Now subtract the second result from the first:

Answer:

Step-by-step explanation:

The product of two whole numbers is 180

xy = 180

and their sum is 36

x+y = 36

x = 36-y

Substitute this into the first equation

(36-y) (y) = 180

36y - y^2 = 180

Add y^2 to each side

36y = 180 +y^2

Subtract 36y from each side

0 = y^2 -36y +180

Factor

0=(y-6) (y-30)

Using the zero product property

y-6 =0   y-30 =0

y = 6    y= 30

Now we need to find x

If y =6

x = 36-6=30

If y = 30

x = 36-30=6

The two numbers are 30 and 6

Answer:

168 miles.

Step-by-step explanation:

5/7x+40+0.75x−118=x

Step 1: Simplify both sides of the equation.

5/7x+40+0.75x−118=x

5/7x+40+0.75x+−118=x

(5/7x+0.75x)+(40+−118)=x(Combine Like Terms)

1.464286x+−78=x

1.464286x−78=x

Step 2: Subtract x from both sides.

1.464286x−78−x=x−x

0.464286x−78=0

Step 3: Add 78 to both sides.

0.464286x−78+78=0+78

0.464286x=78

Step 4: Divide both sides by 0.464286.

0.464286x/0.464286=78/0.464286

x=168

The total length of the bicyclist's route is 560 miles. This is solved by setting up an equation based on the given information and solving for the total route length.

To solve this problem, we first need to represent the problem using equations by setting X as the total route. We know that the bicyclist has already covered 5/7 of his route and an additional 40 miles. So, the part of his route he has already covered is expressed as [tex](5/7)X + 40.[/tex]

We also know that he has yet to cover 118 miles less than 0.75 of his route, so the part of the route that he has yet to cover is expressed as 0.75X - 118. Since the parts of the route already covered and yet to be covered add up to be his entire route (X), we can set up the equation as follows: ([tex](5/7)X + 40 = 0.75X - 118[/tex]. By solving this equation, we find that X (the total length of his route) equals 560 miles.
