Barry has 7 coins, all of which are quarters and nickels. In all, they're worth $1.35. How many of each kind of coin does Barry have?

Answer:

7p¹⁵/ 3q¹²

Step-by-step explanation:

From the question given above,

28p⁹q¯⁵ / 12p¯⁶q⁷

To know which of option is equivalent to the above expression, we shall simplify the expression as shown below:

28p⁹q¯⁵ / 12p¯⁶q⁷

28p⁹q¯⁵ ÷ 12p¯⁶q⁷

Recall:

Xᵐ ÷ Xⁿ = Xᵐ ¯ ⁿ

Therefore,

28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (28/12)p⁹ ¯ ¯⁶q¯⁵ ¯⁷

28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p⁹⁺⁶q¯¹²

28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p¹⁵q¯¹²

Recall:

X¯ⁿ = 1/Xⁿ

Therefore,

(7/3) p¹⁵q¯¹² = (7/3) p¹⁵ × 1/q¹²

(7/3) p¹⁵q¯¹² = 7p¹⁵/ 3q¹²

Hence,

28p⁹q¯⁵ / 12p¯⁶q⁷ = 7p¹⁵/ 3q¹²

Step-by-step explanation:

steps are stated below

step 1

(x-5^2)-7=93  equation

step 2

x-5^2-7=93  remove brackets

step 3

x-5^2-7=93  simplify

x+(-25)+(-7)=93

step 4

(x)+(-25+-7)=93  combine the tems

x+(-32)=93

step 5

x+(-32)=93  change the symbols

x-32=93

step 6

x-32(+32)=93(+32)  add +32 to both sides so we can get our answer

x=-0=93+32

x=125

Answer:

x=15, x=-5

Step-by-step explanation:

Solve:

[tex](x-5)^2-7=93[/tex]

Adding 7:

[tex](x-5)^2=93+7[/tex]

[tex](x-5)^2=100[/tex]

Taking square roots:

[tex]x-5=\sqrt{100}[/tex]

Recall a square root has two possible answers:

[tex]x-5=\pm 10[/tex]

Adding 5:

[tex]x=5\pm 10[/tex]

There are two answers:

[tex]x=5+ 10=15[/tex]

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

Answer:

The equation of line with slope -7 passing through (5,9) in point-slope form is:

[tex]y-9 = -7(x-5)[/tex]

Step-by-step explanation:

Given

Slope of line = m = -7

Point = (5,9)

The point slope form of equation is obtained from a point and slope. It is given by the equation:

[tex]y-y_1 = m(x-x_1)[/tex]

We know that (x1,y1) = (5,9)

Putting the values we get

[tex]y-9 = -7(x-5)[/tex]

Hence,

The equation of line with slope -7 passing through (5,9) in point-slope form is:

[tex]y-9 = -7(x-5)[/tex]

Answer:

The solution is any point in the common part of red and blue

The two lines intersect each other at (4 , 7)

Step-by-step explanation:

∵ y > 1/4 x + 6 ⇒ y = 1/4 x + 6

∵ y > 2x - 1 ⇒ y = 2x - 1

∴ 2x - 1 = 1/4 x + 6

∴ 2x - 1/4 x = 6 + 1

∴ 7/4 x = 7 ⇒ x = 7 ÷ 7/4

∴ x = 4

∴ y = 2(4) - 1 = 7

∴ The two lines intersect each other at (4 , 7)

∴ The solution is any point in the common part of red and blue

Note: You did not mention the ordered pair choices. So, I am letting you clear your concept about taking some sample ordered pairs which anyways would clear your concept.

Answer:

The ordered pairs (1/2, 0) and (0, 1) are on the graph.

The graph is also attached.

Step-by-step explanation:

Given the function

[tex]y= -2x +1[/tex]

Any ordered pair which may satisfy the equation would lie on the graph.

Let us determine the x and y-intercepts.

Determining the x-intercept

We know that the x-intercept can be determined by setting y=0, and the solving for x. so

[tex]y= -2x +1[/tex]

0 = -2x+1

-2x = -1

Divide both sides by -2

x = 1/2

Thus, the x-intercept is (1/2, 0)

Determining the y-intercept

We know that the y-intercept can be determined by setting x=0, and the solving for y. so

[tex]y= -2x +1[/tex]

y = -2(0)+1

y = 1

Thus, the x-intercept is (0, 1)

Thus, the ordered pairs (1/2, 0) and (0, 1) are on the graph.

The graph is also attached.

The ordered pairs (1/2, 0) and (0, 1) are on the graph.

Let us plug x = 0.

So,

[tex]y=-2x+1\\y=-2(0)+1\\y=1[/tex]

So the point is (0, 1).

Let us plug x = 1/2.

So,

[tex]y=-2x+1\\y=-2\left(\frac{1}{2}\right)+1\\y=-1+1\\y=0[/tex]

So the point is (1/2, 0).

Answer:

[tex]A' = -51[/tex]

Step-by-step explanation:

Given

[tex]A = \left[\begin{array}{ccc}-2&2&-5\\4&-1&-2\\1&3&-5\end{array}\right][/tex]

Required

Determine the determinant of A (A')

If

[tex]A = \left[\begin{array}{ccc}a&b&c\\d&e&f\\g&h&i\end{array}\right][/tex]

Then,

[tex]A' = a(e*i - f * h) - b(d * i - g * f) + c(d * h - e * g)[/tex]

So:

The determinant of [tex]A = \left[\begin{array}{ccc}-2&2&-5\\4&-1&-2\\1&3&-5\end{array}\right][/tex] is

[tex]A' = -2(-1 * -5 -(-2)*3) -2(4 * -5 -(-2) * 1) -5(4 * 3- (-1) * 1)[/tex]

[tex]A' = -2(5 +6) -2(-20 +2) -5(12 + 1)[/tex]

[tex]A' = -2(11) -2(-18) -5(13)[/tex]

[tex]A' = -22 +36 -65[/tex]

[tex]A' = -51[/tex]

Hence, the determinant is -51

b = 13

Step-by-step explanation:

5 + b = 18

-5.        -5.     -5 on both sides to get b by itself

b = 13

Answer:

Step-by-step explanation:

angles x, 2x, and 23.7 add up to 180 degrees

x + 2x + 23.7 = 180

3x + 23.7 = 180

subtract 23.7 on both sides

3x + 23.7 - 23.7 = 180 - 23.7

3x = 156.3

divide both sides by 3

x = 52.1

Angle C is a straight line = 180 degrees

Angle B is found by adding 32.5 and x, and subtracting it from 180 degrees (since three angles in a triangle must add up to 180)

we found x = 52.1 degrees

so angle B = 180 - 32.5 - 52.1 = 95.4 degrees

Step-by-step explanation:

used a calculator lol

Answer: x=4

Step-by-step explanation:

We know that line segment AC= AB + BC

we also know that AB= 3x+8 and BC= 2x-5

by substituting these, we get AC= (3x+8)+(2x-5)

AC is given as being 23, so we know that

23= (3x+8)+(2x-5)

by combining like terms, we get that

5x+3=23

simplify this to get that x=4

  loss of $285,000

Step-by-step explanation:

The demand for the Savannah design is estimated to be ...

  Q = 175 -2.1P = 175 -2.1(25) = 122.5 . . . . thousand pens

Then the contribution margin from sales will be ...

  122,500($25 -$6 -$5) = $1,715,000

Against a total of $2,000,000 in production and advertising costs, the net will be a loss of ...

  $2,000,000 -1,715,000 = $285,000

The first-year loss will be $285,000.
