Step-by-step explanation:

the answer is 0

Answer:   0

=================================================

Explanation:

Think of z as having 1 zebra

2z means we have 2 zebras

If we started with 2z, and subtracted off 2z, then we're left with 0 zebras. We write this as 0z or just 0 since 0 times anything is 0.

---------

As another example:

Let's say we wanted to simplify 5z - 2z

Well that's the same as saying "5 zebras take away 2 zebras". We'd be left with 3 zebras because 5-2 = 3

Since 5-2 = 3, this leads to 5z-2z = 3z. The difference is that I tacked 'z's onto each number.

Solve 3(x + 1) = −2(x − 1) − 4
-1
1
-3
5

Answers

Answer:

x = -1

Step-by-step explanation:

3(x + 1) = -2(x - 1 ) - 4

use the distributive property to get rid of the parentheses. on -2 and -1 they cancel each other out so it becomes + 2. now you have:

3x + 3 = -2x + 2 - 4 (+2 and -4 are like terms so they become -2. so technically its 3x + 3 = -2x -2)

get +3 on the other side by subtracting it from itself and then subtracting it from -2 so it becomes -5.

3x = -2x - 5

get -2x on the other side by adding 2x to itself then adding 2x to 3x so it becomes 5x

5x = -5

divide 5 from -5 and you get x = -1

A phone company has two long distance calling plans. The first plan is $25 per month plus $0.01 per minute of long distance calling after the first 100 minutes. The second plan is $10 per month plus $0.05 per minute of long distance calling.
How many minute of long distance calls will it take for the plans to cost the same amount?

Answers

Answer:

286 minutes

Step-by-step explanation:

can you give brainlest or good review

Answer:

Hello!

Let's call X to the number of minutes of long-distance calls you plan to make.

The cost of plan A is given by 25%2B0.05X

The cost of plan B is given by 5%2B0.12X

Plan B is advantageous when its cost is lower than plan A's. Therefore, we set the inequality

5%2B0.12X+%3C+25%2B0.05X

And then solve for X. This will give us the range of minutes for which B is more convenient.

Subtract 5 from both sides of the inequality to get:

0.12X+%3C+20%2B0.05X

Now subtract 0.05X:

0.12X+-+0.05X+%3C+20

0.07X%3C20

Finally, divide by 0.07 to get:

X+%3C+20%2F0.07

X++%3C+285.71

So plan B is advantageous if you plan to use less than 286 minutes of long distance calls.

I hope this helps!

Step-by-step explanation:

The first two answers are correct because they are corresponding. One way of solving is going through each answer and comparing the measurements, if they are congruent then the statement is true, if not it is false.

1) <E=88 and <K=88, since 88=88 this is a true statement.

2) DE=14 mi and JK=14 mi, since 14=14 this is a true statement.

3) CD=14 mi and KL=25 mi, since 14[tex]\neq[/tex]25 this is a false statement.

4) EB=25 mi and MJ=14 mi, since 25[tex]\neq[/tex]14 this is a false statement.

? Dollars per hour

Answers

Answer:

$3.25 multiplied by the hour

Step-by-step explanation:

The slope of the situation if, Martha earns $15 per hour for babysitting, The parents always give her a $5 tip is $15 per hour.

What is the slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Given:

Martha earns $15 per hour for babysitting,

The parents always give her a $5 tip,

The equation for the total money earned by Martha can be written as shown below,

The total money earned = Money per hour for babysitting × number of hours + tip

Assume the total money earned is y, the number of hours is x,

y = 15x + 5

As you can see, the above equation is in slope intercept form,

Slope = $15 per hour

Which of the following is a rational number?

Answers

The square root of 81 is rational since it equals 9. Rational numbers can be expressed as a fraction of two integers. The fraction here would be 9/1, hence it is rational. The others are not perfect squares and can’t be expressed as a fraction of two integers.

If R is the midpoint of PS with PR=6x+16 and RS=-26 then find PS

Answers

Answer:

PS = 116

Step-by-step explanation:

Given:

PR = 6x + 16

RS = 12x - 26

Required:

Find PS

Solution:

Since R is the midpoint of PS, therefore,

PR = RS

6x + 16 = 12x - 26

Collect like terms

6x - 12x = -16 - 26

-6x = -42

Divide both sides by -6

x = -42/-6

x = 7

✔️PS = PR + RS (segment addition postulate)

PS = 6x + 16 + 12x - 26

Plug in the value of x

PS = 6(7) + 16 + 12(7) - 26

PS = 42 + 16 + 84 - 26

PS = 116

Consider a class with 30 students. Compute the probability that at least two of them have their birthdays on the same day. (For simplicity, ignore the leap year.) (b) How many students should be in class in order to have this probability above 0.5

Answers

Answer:

0.7063

Step-by-step explanation:

Given that:

Number of students = 30

Number of days in a year = 365

P(atleast 2 people share same birthday) = 1 - p(none share same Birthday)

p(none share same Birthday) =

(365! / (365 - 30)!) * 1/365^30

(365! / 335!) * 1/365^30

365! ÷ (335! * 365^30)

= 0.2936837

P(atleast 2 people share same birthday) :

1 - 0.2936837

= 0.7063163

= 0.7063 * 100%

= 70.63%
