Answer:

4x19+4x2  or  4x21

Step-by-step explanation:

If you multiply 4x19, you get  76. And if you multiply 4x2 you get 8. 76+8= 84

If you multiply 4x21 you get 84 also.  Both of these answers are distributive property. (all it is, is different ways of solving the problem.)

Hope this helps!  :)

The distance around a circle called Circumference.

Option C is correct.

The circumference of any shape in mathematics defines the route or boundary that surrounds the shape. In other terms, the circumference is also known as the perimeter, and it aids in determining the length of any shape's contour. The perimeter and area of a circle are two important dimensions of a circle, as we all know.

The circumference of the circle, also known as the perimeter of the circle, is the measurement of the circle's boundary.

The area of a circle, on the other hand, defines the region it occupies.

If we open a circle and draw a straight line through it, the length of the line is the circumference.

As, The Circumference (or) perimeter of circle = 2πR

Thus, the distance around a circle called Circumference.

Answer: h -18 =14

Step-by-step explanation:

You need to plug in -18 into the equation. So h(-18)=17+(-18)/6

h(-18)=17-3

h(-18)=14

The value of the number n for the given expression is 21.

In mathematics, an expression is a combination of numbers, variables, operators, and/or functions, which can be evaluated or simplified. Expressions can be simple, such as a single number or variable, or complex, involving multiple operations and variables.

We can begin solving the problem by translating the given sentence into an equation:

"Twice a number, n, added to 13 is equal to 55"

2n + 13 = 55

Next, we can isolate the variable n on one side of the equation by subtracting 13 from both sides:

2n = 55 - 13

2n = 42

Finally, we can solve for n by dividing both sides of the equation by 2:

n = 21

Therefore, the value of the number n is 21.

Step-by-step explanation:

Let Va = the velocity of the airplane

Let Vw = the velocity of the wind

When flying with the wind:

(Va+Vw)*(4 hours) = 4000

4Va + 4Vw = 4000

4Vw = 4000 - 4Va

Vw = 1000 - Va

When flying against the wind:

(Va-Vw)*(7 hours) = 4200 km

7Va - 7Vw = 4200

Substitute 1000-Va for Vw and solve for Va:

7Va - 7(1000-Va) = 4200

7Va -7000 + 7Va = 4200

14Va = 11200

Va = 800 km/hr

Rate of wind:

Vw = 1000 - Va = 1000 - 800 = 200 km/hour

Answer:

Answer:

It depends on the number of charms that your bracelet can have.

here we need to count the number of selections that we have, and the number of options for each one of these selections.

So if we can have only one charm, we have only one selection, and for that selection, we have 9 options, then there are 9 different one-charm bracelets.

If each bracelet can have 2 charms then we have two selections.

For the first selection, we have 9 options,

If each charm can be selected only one time, then for the next selection we will have 8 options, now the total number of combinations is equal to the product between the numbers of options for each selection, so here the total number of combinations is:

C = 9*8 = 72

If we can select 3 charms, then:

first charm = 9 options

second charm = 8 options

third charm = 7 options

Total number of combinations = 9*8*7 = 504 combinations.

Notice that we can not give an exact answer because we do not know the number of charms in each bracelet and we do not know if a charm can be selected multiple times or only one, but here you could see the general way to solve this kind of problems.

Answer:

  a) zeros: -2/3, 6

  b) x < -2/3, signs: -, -; sign of product: +

  -2/3 < x < 6, signs: +, -; sign of product: -

  x > 6, signs: + +; sign of product: +

  c) solution: x < -2/3 ∪ x > 6

Step-by-step explanation:

a) The zeros of the product are the values of x that make either factor zero. (A product is only zero if one of the factors is zero.)

  3x +2 = 0   ⇒   x = -2/3

  x -6 = 0   ⇒   x = 6

The zeros of the quadratic are x = -2/3 and x = 6.

__

b) For values of x left of the left-most zero, both factors are negative. For values of x between the zeros, the left factor is positive and the right factor is negative. For values of x greater than the right-most zero, both factors are positive. That is, for large negative values of x, all factors are negative. Working left-to-right, each time a zero is crossed, one factor changes sign.

__

c) The solution is where the signs of the factors match:

  x < -2/3 or -6 < x

Answer:

Each shirt costs $ 10, while each short costs $ 15.

Step-by-step explanation:

Since two brothers went shopping at a back to school sale where all shirts and shorts are the same price, and the younger brother spent $ 175 on 7 new shirts and 7 pairs of shorts while the older brother purchased 6 new shirts and 7 pairs of shorts and paid a total of $ 165, to determine the price of each shorts and each shirt the following system of equations must be considered:

Shirt = X

Short = Y

7X + 7Y = 175

6X + 7Y = 165

7X - 6X + 7Y - 7Y = 175-165

X = 10

7x10 + 7Y = 175

70 + 7Y = 175

7Y = 175 - 70

Y = 105/7

Y = 15

Thus, each shirt costs $ 10, while each short costs $ 15.

Answer:

x = 9

Step-by-step explanation:

If g(x) = 3, that means that the output is three.

Outputs are y values.

Look at the graph. When y=3, the x  = 9.

So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9
