A 9-pack of markers costs $6.21. What is the unit price?​

Answer:

x=3

Step-by-step explanation:

15 – 2x=3x

Add 2x to each side

15 – 2x+2x=3x+2x

15 = 5x

Divide each side by 5

15/5 = 5x/5

3 =x

Answer:

3

Step-by-step explanation:

15 - 2x = 3x

Add 2x to both sides

15 = 5x

Divide 5 to both sides

3 = x

Best of Luck!

Answer: 0 is a imaginary number

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]20 - \frac{x}{3} = \frac{x}{2} [/tex]

Multiply through by the LCM that's 6 in order to eliminate the fraction

That's

[tex]6 \times 20 - 6 \times \frac{x}{3} = 6 \times \frac{x}{2} \\ 120 - 2x = 3x[/tex]

Using the addition property add 2x to both sides of the equation

That's

[tex]3x + 2x = 120 + 2x - 2x \\ 5x = 120[/tex]

Divide both sides by 5

[tex] \frac{5x}{5} = \frac{120}{5} [/tex]

We have the final answer as

Hope this helps you

Answer:

X=24

Step-by-step explanation:

20=x/2+x/3

20=1/2x +1/3x

20=5/6x

20÷5/6=x

X=24

Answer:

17 , 65

Step-by-step explanation:

x+ y = 82

y = 4x - 3

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

Put the second equation into the first.

x + 4x - 3 = 82

5x = 85

x = 85/5

x = 17

17 + y = 82

x = 82 - 17

x = 65

Answer:

I think B ok sorry if I guess

Step-by-step explanation:

5x-3x=-8-2

2x=-10

x=-10/2

x=-5

Answer: x=-5

Step-by-step explanation:

Given

5x + 2=3x -8

Subtract 2 on both sides

5x + 2 - 2=3x - 8 - 2

5x=3x-10

Subtract 3x on both sides

5x - 3x=3x - 10 -3x

2x=-10

Divide 2 on both sides

2x / 2=-10 / 2

Answer:

-2

Step-by-step explanation:

Value of the function at x = 4 is 12

Value of the function at x = 8 is 4

change in y is  4 - 12 = -8

change in x is 8 - 4 = 4

x = 4 to x = 8 is -8/4 = -2

Answer:1 centiliter

Step-by-step explanation:1 centiliter equals 0.01 liters

Answer:

14.99 ounces

Step-by-step explanation:

First, find the weight of the 2 cereal bags combined:

16.03 + 18.98

= 35.01

Subtract this from 50 to find the weight of the box, since 50 ounces is the combined weight of the box and the 2 cereal bags

50 - 35.01

= 14.99

So, the box weights 14.99 ounces

[tex]Answer:\boxed{4\frac{4}{5}}[/tex]

[tex]Explanation:[/tex]

[tex]9-4\frac{1}{5}[/tex]

Subtract the whole number by the fraction.

[tex]\frac{24}{5}[/tex]

24/5 needs to be simplified so we will rewrite it like this:

Answer:

the answer is B

Step-by-step explanation:

Answer:

$1.26 or $1.27 depending on whether you round up or down. The number in the thousandths is an 8 though

Step-by-step explanation:

You would divide 3.05 by itself to get one pound

and then 3.87 by 3.05. You have to divide both numbers so you get the number for one pound.

3.87÷3.05=1.268852459

Round up or down depending on what your teacher would want you to do so that the decimal is in the hundreths like money.

Answer:

7/41

Step-by-step explanation:

There is a 34/41 probability that this event will happen so to find the probability of which the event will not happen, the subtract 34 from 41 to get your answer.

41-34=7

Therefore, 7/41 is the answer.

Ps. is the P(E) included in the main question? if it is, the the answer might differ from the one I am giving you.

Since these are divided into 6 pieces, go two pieces to the left of zero.

Answer:

72.25

Step-by-step explanation:

17% of 425

=17\100 ×425

=7225/100

=72.25

Answer:

72.25

Step-by-step explanation:

Lets say you are trying to find p percent (p%) of a number n. To do this, you would divide the percent (p) by 100 and multiply it by the number (n). In other words:

[tex]n*\frac{p}{100}[/tex]

We can use this to find 17 percent of 425. 17 would be our percent and 425 would be our number.

[tex]425*\frac{17}{100}=425*0.17=72.25[/tex]

So 17 percent of 425 would be 72.25.

I hope you find my answer and explanation to be helpful. Happy studying. :)

Answer:

x = -7

Step-by-step explanation:

Isolate x by adding 10 to both sides:

-17 = -10 + x

-7 = x

So, x = -7

Step-by-step explanation:

Hey there!!!

Here,

Triangle BCM and triangle ABC are 2 isosceles triangle.

Solving in triangle BCM.

Angle CBM = 31° { it is the base angle.}

Angle CBM + 31° + angle BCM = 180° { sum of interior angle of a triangle is 180°}.

31°+31°+ angle BCM = 180°

Angle BCM = 180° - 62°

Therefore the measure of angle BCM = 118°.

Again,

Solving in triangle ABC.

Angle BCM + angle ACB = 180° { being linear pair}.

118°+ angle ACB = 180°

Angle ACB = 180°-118°

Therefore the measure of angle ACB is 62°.

Angle ACB = angle BAC (Base of an isosceles triangle).

Therefore the measure of angle BAC = 62°.

Now, To find x,

Angle BAC + angle ACB + angle x = 180° (sun of interior angle of a triangle is 180°).

62°+62°+angle x = 180°

Therefore the measure of angle x is 56°.

Hey there!

[tex]\frac{2}{3}=\frac{x}{9}[/tex]

For the first step, we will need to use the cross multiplying method.

[tex]\frac{2}{3} =\frac{x}{9}\\ (2)*(9)=(x)*(3)\\18=3x[/tex]

Now let's flip.

[tex]3x=18[/tex]

Now for the final step, we will have to divide both sides by 3.

[tex]\frac{3x}{3} equals\frac{18}{3}[/tex]

Simplify 18/3.

Answer:

16 will be added.

Step-by-step explanation:

Given equation is,

x² - 8x = 10

To convert this equation into a square form we will follow the following steps,

Step (1). x² - 2(4x) = 10

Step (2). x² -2(x)(4) + 16 = 10 + 16

Step (3). x² - 2(4)(x) + 4² = 26

Step (4). (x - 4)² = 26

In step (2) we have added 16 to both the sides of the equation to make is a perfect square.
