13 - (-6) subtracting integers

Step-by-step explanation:

5(r + 9) - 2(1 - r) = 1

5r + 45 - 2 + 2r = 1

7r + 43 = 1

7r = -42

r = -6.

Answer:

r = -6

Step-by-step explanation:

Given equation,

→ 5(r + 9) - 2(1 - r) = 1

Now the value of r will be,

→ 5(r + 9) - 2(1 - r) = 1

→ 5r + 45 - 2 + 2r = 1

→ 5r + 2r + 43 = 1

→ 7r = 1 - 43

→ 7r = -42

→ r = -42/7

→ [ r = -6 ]

Hence, the value of r is -6.

Answer:

t = [tex]\frac{s-5}{2}[/tex]

Step-by-step explanation:

Given

s = 2t + 5 ( subtract 5 from both sides )

s - 5 = 2t ( divide both sides by 2 )

[tex]\frac{s-5}{2}[/tex] = t

Answer:

she bought 8.5 pounds of jellybeans

Step-by-step explanation:

12.75 divided by 1.5 gets 8.5

p=1

Step-by-step explanation:

[tex]3p + 7 = - 4(4 - 6p) + 2 \\ 3p + 7 = - 16 + 24p + 2 \\ 3p - 24p = - 16 + 2 - 7 \\ - 21p = - 21[/tex]

[tex] \frac{ - 21p}{ - 21} = \frac{ - 21}{ - 21} \\ p = 1[/tex]

Answer:

p = 1

Step-by-step explanation:

Given

3p + 7 = - 4(4 - 6p) + 2 ← distribute and simplify right side

3p + 7 = - 16 + 24p + 2

3p + 7 = 24p - 14 ( subtract 3p from both sides )

7 = 21p - 14 ( add 14 to both sides )

21 = 21p ( divide both sides by 21 )

1 = p , that is p = 1

Step-by-step explanation:

(a): 5x^2 + 25 = 5 * x^2 + 5 * 5 = 5(x^2 + 5).

(b): 2x^2 - 3x - 2 = 2x^2 - 4x + x - 2

= 2x(x - 2) + 1(x - 2) = (2x + 1)(x - 2).

Answer:

x = 2

Step-by-step explanation:

37 = -3 + 5(x+6)

37 + 3 = 5*x + 5*6

40 = 5x + 30

40 - 30 = 5x

10 = 5x

x = 10/5

x = 2

Check:

37 = -3 + 5(2+6)

37 = -3 + 5*8

37 = 40 - 3

Answer:

Interval width

Step-by-step explanation:

In normal statistics, we calculate range as difference between Maximum Value and Minimum Value of the data given.

However, in group simple frequency distribution, we have what we call interval width which is simply the range of values contained in each interval.

To determine this interval width, we we divide the observed range by the number of intervals chosen.

Answer:

The greater than of -7 is 7. The less than -2 is 2.

Step-by-step explanation:

It's the same distance from both but, the positive number always been greater than negative number.

Both questions have an infinite number of correct answers.

Here are six numbers that are greater than -7:

-6.99999,  -4,  0,  3,  π,  4.00001

Here are six numbers that are less than -2:

-2.00001,  -3,  -π,  -4,  -136,  -201.358

Answer:

adult tickets  6.9

children tickets  3.9

Step-by-step explanation:

3x + y = 24.60    L1

5x + 4y = 50.10  L2

5L1 - 3L2

15x +  5y = 123

-15x - 12y = -150.3

-7y = -27,3

y = -27,3/-7

y = 3.9

3x + y = 24.60

3x + 3.9 = 24.60

3x = 24.60 - 3.9

3x = 20.7

x = 20.7 / 3

x = 6.9

Answer:  31°

Step-by-step explanation:

Supplementary angles add up to 180 degrees so add 149 degrees to a number of degrees to get 180 degrees.That can be represent by the equation,

149 + x = 180  where x is the supplement so solve for x

-149         -149

x = 31

Answer: The number is -12

Step-by-step explanation:

The situation can be represent by the equation  

 [tex]\frac{n}{-2} = -4 + 10[/tex]     Now solve for n   by combining like terms on the right side

[tex]\frac{n}{-2}[/tex] = 6     multiply both sides by -2  

n = -12

Answer:

Step-by-step explanation:

1. y = 13x + 5

y = 13(0) + 5

y = 0 + 5

y = 5

(0,5)

y = 13(-2) + 5

y = -26 + 5

y = -21

(-2, -21)

2. y = -3x

y = -3(-3)

y = 9

y = -3(0)

y = 0

(0,0)

(-3,9)

3. y = x - 10

   y = -5 - 10

    y = -15

   (-5, -15)

  y = 8 - 10

   y = -2

   (8, -2)

The correct options are:

1. y = 13x + 5  ⇒ (0,5)

2. y = -3x ⇒ (0,0)

3. y = x - 10  ⇒ (8, -2)
