let's solve ~

[tex]3x + 2 = x + 28[/tex]

now let's deduct x from both sides ~

[tex]3x + 2 - x = x + 28 - x[/tex]

[tex]2x + 2 = 28[/tex]

therefore, the missing term in the box is ~ 2

[tex] \boxed{2}x + 2 = 28[/tex]

Answer:

? = 2

Step-by-step explanation:

To get the x to the other side, subtract x on both sides, then combine like terms.

[tex]3x+2=x+28\\3x+2-x=x+28-x\\2x+2=28[/tex]

Mrs Granger is writing problems for a test about subtracting fractions.Help her write two different subtraction problems that use only odd numbers for numerators and each have a difference of 3/4

Answers

1.

The first subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is 1 - ¹/₄

The first subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is

1 - ¹/₄ = ¹/₁ - ¹/₄

taking the L.C.M which is 4, we have

= (4 - 1)/4

= 3/4

So, the first subtraction problem is 1 - ¹/₄

2.

The second subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is 2¹/₂ - 1³/₄

The second subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is

2¹/₂ - 1³/₄ = ⁵/₂ - ⁷/₄

taking the L.C.M which is 4, we have

= (10 - 7)/4

= 3/4

So, the second subtraction problem is 2¹/₂ - 1³/₄

Answers

The expression above can be resolved to become; (5a + b)³

According to the question:

We are required to determine resolve the expression as given in the question.

To resolve the expression given;

We are required to multiply the polynomials as follows;

(5a + b) (25a² + 10ab² + b²)

= 125a³ + 50a²b² + 5ab² + 25a²b + 10ab³ + b³

The AVID teachers are collecting boxes for charity. They have asked 60 teachers to donate 5 boxes. if 20% of the teachers donate 5 boxes each, how many boxes will AVID collect? please show work

Answers

Answer:

60 boxes

Step-by-step explanation:

1. First find 20% of 60 (multiply 60 by .2) to get 12.

2. So 12 teachers will donate 5 boxes each (12 x 5=60)

Answer: The answer would be 60 boxes.

Step-by-step explanation: If there are 60 teachers and only 20% of the teachers donate, then you could say that there is only 0.2 of the teachers who donated boxes. This gives you 0.2 times 60 which equals 12. If each teacher donates 5 boxes each and there are 12 teachers who donated, then there would be a total of 60 boxes donated.

Hope this helps.

Juwan went on a bike ride of 36 miles. He realized that if he had gone 15 mph faster, he would have arrived
10 hours sooner. How fast did he actually ride?

Answers

Step-by-step explanation:

Distance = (Rate)(Time) So, Time = (Distance)/(Rate)

Time at slower speed = Time at faster speed + 3

36/x = 36/(x+6) + 3

Multiply the equation by the LCD, x(x+6) to obtain:

36(x+6) = 36x + 3x(x+6)

36x + 216 = 36x + 3x2 + 18x

3x2 + 18x - 216 = 0

x2 + 6x - 72 = 0

(x + 12)(x - 6) = 0

x = -12 or x = 6

Since x can't be negative, x = 6 mph
