Answer:

y = 3

Step-by-step explanation:

[tex]y + 2 = 5 \\ y = 5 - 2 \\ y = 3[/tex]

Answer:

y = 3

Step-by-step explanation:

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:

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]

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:

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:

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:

x = 3/2

Step-by-step explanation:

3^(x-1)=(√3)

Rewriting sqrt(3) as 3 ^ 1/2

3^(x-1)= 3 ^ (1/2)

The bases are the same so the exponents are the same

x-1 = 1/2

Add 1 to each side

x-1+1 = 1/2 +1

x = 3/2

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]

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:

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:

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.
