Answer:

m = 5

n = 12

Step-by-step explanation:

Opposite sides in a parallelogram are equal

so:

m+1 = 6

m = 6-1

m = 5

n is opposite to 12 so n = 12

Answer:

I think it's "inverse property of addition"

Answer:

Friday

Step-by-step explanation:

We can use logic/equations to solve this problem.

Let's create the equation:

the day before the day before yesterday = saturday + 3 days

We can simplify the right side down.

3 days after Saturday is Tuesday.

So:

the day before the day before yesterday = Tuesday

The day before the day before yesterday is the same as 3 days before today. So:

3 days before today = Tuesday

This means that today is 3 days after Tuesday. 3 days after Tuesday is Friday, so today is a Friday.

Hope this helped!

Answer:

Step-by-step explanation:

at 7 the temperature=-6

at 8 the temperature=2

difference=8 degree

Answer:

- 8°

Explanation:

→ We write the data problems.

→ in Wilton - 7:00 am ⇒ - 6°

                    8:00 am ⇒   2°

What is the difference in the temperature between 8:00 am and 7:00 am?

- 6° - 2° = - 8°

Answer:

Numerical length of VX = 20

Step-by-step explanation:

Given that VX is a line segment which has a point W on it.

Kindly refer to the attached diagram for the given points.

We are also given the following dimensions:

[tex]VX=4x\\VW=3x\ and \\WX=5[/tex]

To find:

Numerical length of VX = ?

Solution:

As we can clearly see from the attached diagram:

[tex]VX = VW + WX[/tex]

Putting the given values:

[tex]4x=3x+5[/tex]

Now, let us solve for [tex]x[/tex] and then will put the value of [tex]x[/tex] back to find the numerical value of VX.

[tex]\Rightarrow 4x-3x=5\\\Rightarrow x =5[/tex]

Now,

[tex]VX = 4 \times x = 4\times 5 =\bold{20}[/tex]

Therefore, numerical value of VX is 20.

Answer:

x represents the trip distance.

x = 300 miles

Rate of bus = 50 mph

Rate of train = 75 mph

Step-by-step explanation:

Let the trip distance be x miles.

[tex] \because \: speed = \frac{distance}{time} \\ time \: taken \: by \: bus \: to \: complete \: \\ the \: trip \: = 6 \: hours \\ \therefore \: speed \: of \: bus = \frac{x}{6} \: mph \\ \\ time \: taken \: by \: train \: to \: complete \: \\ the \: same \: trip \: = 4 \: hours \\ \therefore \: speed \: of \: train = \frac{x}{4} \: mph \\ \\ \because \: \: speed \: of \: train \\ =speed \: of \: bus \: + 25 \: mph \\ \therefore \: \frac{x}{4} = \frac{x}{6} + 25 \\ \\ \therefore \: \frac{x}{4} - \frac{x}{6} = 25 \\ \\ \therefore \: \frac{6x - 4x}{4 \times 6} = 25 \\ \\ \therefore \: \frac{2x}{24} = 25 \\ \\\therefore \: \frac{x}{12} = 25 \\ \\ \implies \: x = 25 \times 12 \\ \implies \: x =300 \: miles \\ \\ rate \: of \: bus = \frac{x}{6} = \frac{300}{6} = 50 \: mph\\ \\ rate \: of \: train = \frac{x}{4} = \frac{300}{4} = 75 \: mph[/tex]

Answer:

Number of games = 4

Step-by-step explanation:

Let the number of games = x

Family Bowling Alley charges $1 for shoes and $4 dollars per game

If x games is played

Cost= 1+4(x)

Knight Owl Bowling charges $2 for shoes and $3.75 per game.

If x games is played

Cost = 2 + 3.75(x)

When the both cost are equal

1+4(x)= 2+3.75(x)

4x-3.75x = 2-1

0.25x = 1

X= 1/0.25

X= 4

Number of games = 4

Answer:

D. [tex]-y > 10[/tex]

Step-by-step explanation:

First, move the variable (+ 2y) to the left-hand side and change its sign.

[tex]y - 2y - 7 > 3[/tex]

Then, move the constant (+ 7) to the right-hand side and change its sign.

[tex]y - 2y > 3 + 7[/tex]

Then, collect the like terms (y - 2y)

[tex]-y > 3 + 7[/tex]

Finally, add the numbers (3 + 7). That will get you your final answer.

[tex]-y > 10[/tex]

Answer:

The answer is 393/1000

Step-by-step explanation:

Answer:

131/333 is the correct answer

Step-by-step explanation:

Answer:

  [tex]F(x)=\left\{\begin{array}{cl}15(40-x)&\text{if $0<x<40$}\\0&\text{if $40\le x\le65$}\\15(x-65)&\text{if $x>65$}\end{array}\right.[/tex]

Step-by-step explanation:

(a) For x below 40, the number of miles per hour below 40 is (40-x). Then the fine for that speed is 15(40 -x).

For x between limits, the fine is zero.

For x above 65, the number of miles per hour above 65 is (x-65). Then the fine for that speed is 15(x -65).

  [tex]F(x)=\left\{\begin{array}{cl}15(40-x)&\text{if $0<x<40$}\\0&\text{if $40\le x\le65$}\\15(x-65)&\text{if $x>65$}\end{array}\right.[/tex]

Answer:

6+(-3) is 3 units from 6 in the right direction

Step-by-step explanation:

6 + (​ - 3 ) is​ 3 units from ​6, in the​ right direction.

An integer is the number zero, a positive natural number or a negative integer with a minus sign. The negative numbers are the additive inverses of the corresponding positive numbers.

Given:

6 + (​ - 3 ) is​ ___ units from ​6, in the​ ___ direction.

as we know that  6 +(-3) = +3 units

So, -3 is 3 units away but the direction depend on the sign between the numbers.

Then, according to the sign the direction is on right side.

Hence, 6 + (​ - 3 ) is​ 3 units from ​6, in the​ right direction.

Step-by-step explanation:

Answer:

I'm pretty sure its rational.

Step-by-step explanation:

Rational, I'm pretty sure is like above negative numbers. Irrational is like negative numbers, and yeah...I could be wrong. But I'm sure its rational.

Answer:

B. Rational, not an integer

Answer:

A(c+b)=d.

Ac+Ab=d.

Ac=d-Ab.

Divide through by A.

c=d-ab/a.

Option A.

Steps to solve:

a(c + b) = d

~Distribute

ac + ab = d

~Subtract ab to both sides

ac = d - ab

~Divide a to both sides

c = d-ab/a (Option 1)

Answer:

m<bec = 60

Step-by-step explanation:

3x +2x +x = 180 (combine like terms)

6x = 180 (divide 180 by 6 to get x alone on one side of the equation)

x = 30

BUT you're not done yet because it asked for m<bec which is 2x so you have to multiply 30(2) which is 60

Answer:

A, B, & C

Step-by-step explanation:

A: -5x +12 = -12x - 12

    +12x        +12x

    7x + 12 = -12

         -12     -12

            7x = -24                 [Divide both sides by 7 to get x]

              x = -24/7

B: −5x + 12 = 5x + 12

   -5x            -5x

    -10x + 12 = 12

            -12     -12

            -10x = 0                   [Divide both sides by -10 to get x]

                 x = 0

C: −5x + 12 = 5x − 5

    -5x           -5x

    -10x + 12 = -5

            -12      -12

           -10x = -17                  [Divide both sides by -10 to get x]

               x = 17 / 10

D: −5x + 12 = −5x − 12

    +5x           +5x

              12 ≠ -12         [The statement is false, so it isn't the correct answer]
