77 meter=_____dm ?

Can someone help ?

Steps to solve:

2x - 3 = 5x + 6

~Add 3 to both sides

2x = 5x + 9

~Subtract 5x to both sides

-x = 9

~Divide -1 to both sides

x = -3

Solve for 4x using x = -3

4(-3) = -12

Therefore, the answer is x = -12

Answer: 19.42

Step-by-step explanation:

To find the distance, we need to use the distance formula.

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

With the given points, we can plug them in and solve.

[tex]d=\sqrt{(7-3)^2+(-11-8)^2}[/tex]          [parenthesis]

[tex]d=\sqrt{(4)^2+(-19)^2}[/tex]                       [exponent]

[tex]d=\sqrt{16+361}[/tex]                               [add]

[tex]d=\sqrt{377}[/tex]                                       [square root]

[tex]d=19.42[/tex]

Now, we know the distance is 19.42.

Answer:

[tex]x=7[/tex]

Step-by-step explanation:

Since AB bisects AC, AB = BC.

[tex]x+12=6x-23[/tex]

Subtract 12 from both sides:

[tex]x+12-12=6x-23-12[/tex]

[tex]x=6x-35[/tex]

Subtract 6x from both sides:

[tex]x-6x=6x-35-6x[/tex]

[tex]-5x=-35[/tex]

Divide both sides by -5:

[tex]\frac{-5x}{-5}=\frac{-35}{-5}[/tex]

[tex]x=7[/tex]

Answer:

a. They are same side interior angles. Angle A measures 55°.

Step-by-step explanation:

They are the same side interior angles. Angle A measures 55°.

If you think about it, you'll see that when you add any of the interior angles of a triangle to its neighboring exterior angle, you always get 180 degrees a straight line.

Interior angles are those that lie inside a polygon. For example, a triangle has 3 interior angles. The other way to define interior angles is "angles enclosed in the interior region of two parallel lines when intersected by a transversal are known as interior angles".

Answer:

1.4959787 × 10^8

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.

Follow the steps below to see how 149,597,870 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 149,597,870

New Number: 1.49597870

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 4 9 5 9 7 8 7 0

Decimal Count: 1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10^b

a = 1.4959787 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.4959787 x 10^8

Step 4

Check your work:

10^8 = 100,000,000 x 1.4959787 = 149,597,870

Probability of a student choosing grape flavor:

Answer is 0.2

Probability that a student who bought juice chosen at random purchased the grape flavor is 0.2.

According to the question, there are three lunch periods and the number of students that take different flavors of juice is shown below;

Since probability = Expected outcome/sample space

Sample space = 51 + 30 + 69 = 150

Probability that a student who bought juice chosen at random purchased the grape flavor = 30/150 = 0.2

Answer: y = -1x + 5

Step-by-step explanation:

1. Plug the coordinates into the slope formula (y2 - y1)/ (x2 - x1)

(0 - 6)/ (5 -(-1))

2. Solve for slope

-6/6

= -1

3. Plug the first coordinate and slope into the point slope form equation (y - y1) = slope(x - x1) to find the rest of the equation of the line

(y -(-1)) = -1( x - 6)

4. Solve for y

y + 1 = -1x + 6 -----> y = -1x + 5

Step-by-step explanation:

Answer:

The coordinates of point B are (23,-2)

Step-by-step explanation:

Mathematically, what this question is telling us is that the point P divides the segment AB in the ratio 2:3

We are now tasked with finding the coordinates of point B

For point P to have divided the segment in that particular ratio, then, internal division formula would have been used.

Mathematically, the internal division formula is given as;

(x,y) = (mx2 + nx1)/(m + n) , (my2 + ny1)/(m + n)

In this particular question case;

(x,y) are coordinates of p = (8,1)

x = 8 , y = 1

m = 2 , n = 3

x1 = -2 , y1 = 3

x2 = x , y2 = y ( coordinates of point B)

So let’s make the substitution;

(8,1) = 2x + 3(-2)/2+3) , 2(y) + 3(3)/(2+3)

(8,1) = (2x-6)/5 , (2y + 9)/5

So therefore; let’s equate

(2x-6)/5 = 8

and 2y+ 9/5 = 1

2x-6/5 = 8

2x -6 = 8*5

2x -6 = 40

2x = 40 + 6

2x = 46

x = 46/2

x = 23

(2y + 9)/5 = 1

2y + 9 = 5 * 1

2y + 9 = 5

2y = 5-9

2y = -4

y = -4/2

y = -2

So the coordinates of point B are (23,-2)

Answer:

f(x) = |x| represents the modulus function or absolute value function. It gives us the distance between any point and the origin. Since distance can never be negative so we always consider its positive value only. You can simply multiply the given value with ‘-1’(if the given value is negative).
