Maria bought 3 books for a total of $26. 25. How much did each book cost?

Step-by-step explanation:

[tex] \frac{2}{3} v + \frac{1}{6} = \frac{7}{9}v - \frac{5}{6} [/tex]

[tex] \frac{1}{6} + \frac{5}{6} = \frac{7}{9} v - \frac{2}{3} v[/tex]

[tex] \frac{6}{6} = ( \frac{7}{9} \times \frac{2}{3} )v[/tex]

[tex]1 = ( \frac{7}{9} - \frac{2 \times 3}{3 \times 3} )v[/tex]

[tex]1 = ( \frac{7}{9} - \frac{6}{9} )v[/tex]

[tex]1 = ( \frac{7 - 6}{9} )v[/tex]

[tex]1 = ( \frac{1}{9} )v[/tex]

[tex]v = 9[/tex]

Answer:

J (−3, 5) → J ′(−7, 12) → J ″(−7, −12);

K (−1, 0) → K ′(−5, 7)→ K ″(−5, −7);

L (8, −4)→ L ′(4, 3)→ L ″(4, −3)

Step-by-step explantion

Use the translation vector <−4, 7>  to determine the rule for translation of the coordinates: (x,y)→(x+(−4),y+7).

Apply the rule to translate vertices J(−3,5), K(−1,0) and L(8,−4).

J(−3,5)→(−3+(−4),5+7)→J'(−7,12).

K(−1,0)→(−1+(−4),0+7)→K'(−5,7).

L(8,−4)→(8+(−4),−4+7)→L'(4,3).

To apply the reflection across x-axis use the rule for reflection: (x,y)→(x,−y).

Apply the reflection rule to the vertices of △J'K'L'.

J'(−7, 12)→J''(−7,−12).

K'(−5,7)→K''(−5,−7).

L'(4,3)→L''(4,−3).

Therefore,

J(−3,5)→J'(−7,12)→J''(−7,−12)K(−1,0)→K'(−5,7)→K''(−5,−7)

L(8,−4)→L'(4, 3)→L''(4,−3)

represents the translation of △JKL along vector <−4, 7>  and its reflection across the x-axis.

Answer:

Step-by-step explanation:

Given :

x = -6

-7x + 6y = -18 ... i)

Putting the value of x in equation ...i)

=> -7 (-6) + 6y = -18

=> 42 + 6y = -18

=> 6y = -18 -42

=> 6y = - 60

=> y = -60/6

=> y = -10

The value of y = -10 and x = -6

Answer:

x= 4, y=6

Step-by-step explanation:

9x-9y = -18

9x=-18+9y

x=-2+y

-6(-2+y) + 9y = 6

-12-6y+9y=6

3y=18

y=6

9x -9(6)=-18

9x-54=-16

Step-by-step explanation:

Let's assume the final answer is x

x = 448

The measure of angle BOC is 28.65°.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

The area of a triangle is,

Area = 1/2 × base × height

We have radius of the circle is 12 inches since OA = 12 which is the radius.

So, OB = 12 inches.

Height of the triangle AOB to the base OA = 12 sin (30°) = 12/2 = 6 inches

Area of ΔAOB = 1/2 × 12 × 6 = 36 inches²

Area of sector = (x/360°) πr², where r is the radius and x is the central angle formed.

Here x is ∠BOC.

Since area of sector = area of triangle,

(x/360°) π(12)² = 36

x π = 90°

x = 28.65°

Hence the required measure is 28.65°.

Answer:

54

Step-by-step explanation:

If 5 students went in cars then 216 students were in the buses (221-5=216)

There were four buses so divide 216 by 5 which is 54.

So there were 54 students in each bus

Answer:

54

Step-by-step explanation:

If you have 221 students going to the zoo and 5 that went to the zoo in cars you only need to account for the 216 travelling by bus. So you subtract 5 from 221 and divide what you have left over (216) by 4 for the 4 buses you're using.

216/4= 54

We want to find the number of ways that a cook can arrange 8 of 12 spice jars on a spice rack.

This is a Combination Problem which follows the formula;

nCr = n!/(r!(n - r)!

12C8 = 12!/(8!(12 - 8)!

Solving this gives;

12C8 = 495 ways

Thus, the number of ways that a cook can arrange 8 of 12 spice jars on a spice rack is 495 ways.

Answer:

[tex]y=-5(x+2)-1[/tex]

[tex]y=-5(x+3)+4[/tex]

Step-by-step explanation:

Two points on the line are (-3, 4) and (-2, -1)

Therefore:

[tex]\textsf{let}\:(x_1,y_1)=(-3,4)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(-2,-1)[/tex]

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-4}{-2-(-3)}=-5[/tex]

Point-slope form of linear equation:  [tex]y-y_1=m(x-x_1)[/tex]

Substituting point (-3, 4) in the point-slope equation:

[tex]\implies y-4=-5(x-(-3))[/tex]

[tex]\implies y=-5(x+3)+4[/tex]

Substituting point (-2, -1) in the point-slope equation:

[tex]\implies y-(-1)=-5(x-(-2))[/tex]

[tex]\implies y=-5(x+2)-1[/tex]

Answer:

Step-by-step explanation:

15/2 = 7.5 and (7.5)^2 = 56.25  so

x^2 + 15x + 56.25 = 49 + 56.25

x^2 + 15x + 56.25 = 105.25.

Answer:

[tex]x^2+15x+\boxed{\dfrac{225}{4}}=\boxed{\dfrac{421}{4}}[/tex]

[tex]x^2+15x+\boxed{56.25}=\boxed{105.25}[/tex]

Step-by-step explanation:

General form of a quadratic equation: [tex]ax^2+bx+c[/tex]

When completing the square, first add the number that is the square of half of [tex]b[/tex].

Given equation:  [tex]x^2+15x=49[/tex]

Therefore, [tex]b=15[/tex]

[tex]\implies \left(\dfrac{b}{2}\right)^2=\left(\dfrac{15}{2}\right)^2=\dfrac{225}{4}[/tex]

So we need to add 225/4 to both sides of the equation:

[tex]\implies x^2+15x+\dfrac{225}{4}=49+\dfrac{225}{4}[/tex]

[tex]\implies x^2+15x+\boxed{\dfrac{225}{4}}=\boxed{\dfrac{421}{4}}[/tex]

In decimal form:

[tex]\implies x^2+15x+\boxed{56.25}=\boxed{105.25}[/tex]

To finish completing the square,

factor the left side of the equation:

[tex]\implies \left(x+\dfrac{15}{2}\right)^2=\dfrac{421}{4}[/tex]

Finally, subtract 421/4 from both sides:

[tex]\implies \left(x+\dfrac{15}{2}\right)^2-\dfrac{421}{4}=0[/tex]

In decimal form:

[tex]\implies (x+7.5)^2-105.25=0[/tex]

Step-by-step explanation:

Answer:

p = [tex]-\frac{15}{2}[/tex], p = [tex]\frac{17}{2}[/tex]

Step-by-step explanation:

1. Subtract 15 from both sides:

- |2p -1| = -16

2. Divide both sides by -1:

[tex]\frac{-|2p - 1|}{-1} = \frac{-16}{-1}[/tex]

|2p - 1| = 16

3. Apply the absolute value rule (If |u| = a, a > 0, then u = a, or u = -a)

2p - 1 = 16  or  2p - 1 = -16

4. Solve for the positive and negative intervals:

2p - 1+1 = 16+1

2p = 17

[tex]\frac{2p}{2} = \frac{17}{2}[/tex]

p = [tex]\frac{17}{2}[/tex]

2p - 1+1 = -16+1

2p = -15

[tex]\frac{2p}{2} = \frac{-15}{2}[/tex]

p = [tex]\frac{-15}{2}[/tex]
