Scott went snowboarding down a mountain. The trail was 2 miles long and took him 5 minutes to complete. If Tom snowboards three times as fast, how long would it take him to get down the mountain?

Answer:

It's a - (minus) sign.

Answer:

x =  15

Step-by-step explanation:

Given in the question an equation

31 = 3x - 14

Solution

rearrange the constant to the right of equation

3x = 14 + 31

3x = 45

divide 3 on both sides of the equation

3x/3 = 45/3

      x = 15

Answer:

x=15

Step-by-step explanation:

The given equation is;

31=3x-14

Group similar terms:

31+14=3x

Combine the left hand side to obtain;

45=3x

Divide both sides by 3 to get;

[tex]x=\frac{45}{3}[/tex]

x=15

Step-by-step explanation:

I think the answer is x=-4,x=+6

The values of the x are +6 and -4. The values of the x are obtained by the factorization method.

They are mathematical formulas containing variables raised by non-negative integers, coefficient, and constants involving only addition, subtraction, multiplication, and non-negative exponentiation of variables.

The given expression is;

x²-2x-24= 0

By factorization;

x²-6x+4x-24=0

After taking common terms, we get ;

x²-6x+4x-24=0

x(x-6)+4(x-6)=0

(x+4)(x-6)=0

The value of the x is found as;

x-4=0

x=-4

x-6=0

x=+6

Hence, the values of the x are +6 and -4.

x = 20

Step-by-step explanation:

Adjacent angles on straight line add up to 180º

7x + (x + 20) = 180

7x + x + 20 = 180

8x + 20 = 180

8x = 160

x = 20

Two angles whose sum is 180° are called supplementary angles. The value of x is 20°.

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

The sum of the measure of the angle will be supplementary to each other because the two angles together will be a line. Therefore, the sum will be,

7x + (x+20°) = 180°

7x + x + 20° = 180°

8x = 160°

x = 20°

Hence, the value of x is 20°.

209 seats were used by men and boys. i took 45% of 380 which = 171. I subtracted that by 380 which = 209.

Answer with Step-by-step explanation:

0.45 of the total seats were used by women and girls.

i.e. Remaining 0.55(1-0.45) of the total seats were used by men and boys.

Seats used by men and boys=55% of 380

                                               [tex]= \dfrac{55}{100}\times 380\\\\ =209[/tex]

Hence, Seats used by men and boys is:

and the fraction of total number of seats used by men and boys(0.55) is greater than that of total seats used by women and girls(0.45).

Answer:

Step-by-step explanation:

For this, both sides added together will need to equal 180°.

Now, solve for p

p+28+3p=180

    -28 .       -28

Answer:

The volume of oblique cylinders is the same volume as a right cylinder of the same radius and height. The height of cylinder must be the perpendicular height, but as long as the radius and height are the same the volume does not change, which is why the same formula can be used for both oblique and right cylinder.

For skewed and right prism, base length and height does not change, volume for both is calculated by area times height.

The correct anwser would be 56

The volume of the prism filled with 30 cubes with side lengths of 1/2 unit is 3.75 cubic units.

To calculate the volume of a cube with a side length of 1/2 unit, we use the formula V = s³, where s is the side length of the cube.

For a side length of 1/2 unit, the volume of one cube is V = (1/2)³ cubic units.

Therefore, the volume of one such cube is 1/8 cubic units. If the prism is filled with 30 such cubes, we multiply the volume of one cube by the number of cubes:

Total Volume = Number of Cubes × Volume of One Cube = 30 × 1/8 cubic units = 30/8, which simplifies to 3.75 cubic units.

[tex]y= 2^x + 3\\\\y-3=2^x\\\\log_2(y-3)=log_2(2^x)\\\\x=log_2(y-3)[/tex]

[tex] \frac{1}{2} \times 21.6 \times 5.9 = 63.72[/tex]

The area of this triangle is 63.72 square feet.

The distance between two points on a number line is found using the absolute value of their difference. For instance, the distance between 2 and 14 is 12 units, and the distance between -10 and 8 is 18 units.

The concept of absolute value is crucial when determining the distance between two points on a number line. This distance is represented by the difference in their values, disregarding which one is larger or whether they are positive or negative.

The expression for the distance is |2 - 14|. Evaluating this, we find |2 - 14| = |-12| = 12. Therefore, the distance between the numbers 2 and 14 on the number line is 12 units.

The expression for the distance is |-10 - 8|. Evaluating this, we find |-10 - 8| = |-18| = 18. Therefore, the distance between the numbers -10 and 8 on the number line is 18 units.

Answer:

21 articles of clothing are clean.

Step-by-step explanation:

If 2/5 clothes, or 40% of them, are dirty, then 3/5, or 60% of them are clean.

Multiply 35 by 0.60, and you get your answer.

35 x 0.60 = 21.

We can check this answer by multiplying 0.40 by 35 to get the amount of dirty clothes and adding that amount to 21, which should equal 35.

35 x 0.40 = 14

14 + 21 = 35

To find out how many articles of clothing were clean, we set up a ratio equation using the given ratio of 2 to 5. By representing the number of clean clothes with a variable and using the total count of 35 clothes, we determined that Meredith found 10 clean articles of clothing.

When Meredith cleaned her room, she found that the ratio of clean clothes to dirty clothes was 2 to 5. If there were 35 articles of clothing in total, the problem can be approached by assigning a variable to represent the number of clean clothes. Let's denote the number of clean clothes by c and the number of dirty clothes by d.

Based on the given ratio, we can write the equation as 2/5 = c/d. Since we know that c + d = 35, we can use these two equations to solve for c.

We express d in terms of c as d = 35 - c.

Substituting this into the ratio equation, we get 2/5 = c/(35 - c). Cross multiplying gives us 5c = 2(35 - c), which simplifies to 5c = 70 - 2c.

Solving for c, we add 2c to both sides to get 7c = 70. Dividing both sides by 7 gives us c = 10. Therefore, Meredith found 10 clean articles of clothing.
