15 more than x minus 2 write algebraic expressions

Answer:

9

Step-by-step explanation:

x^2 - 2 = 79

The first step is to get rid of the 2 on the left side. You do this by adding two on both sides. You should then get x^2 = 81.

Now, you have the just take the square root of 81, which is 9.

Answer:

x = 20

Step-by-step explanation:

x° + 2x° + (x + 10)° = 90° ( complementary angles)

(4x + 10) ° = 90°

4x + 10 = 90

4x = 90 - 10

4x = 80

x = 80/4

x = 20

Answer:

20°

Step-by-step explanation:

#thanks me late,thankyou

Answer:

D. 90°

Step-by-step explanation:

6x + 4x - 1 + 2x + 1 = 180

12x = 180

x = 15

6x = 6 * 15 = 90

Answer: D. 90°

Answer:

n = 2

Step-by-step explanation:

-1 + 3 = 2

Answer:

Range = {3, -1, 15}

Step-by-step explanation:

Domain = {0,2,-6}

function : y= -2x + 3

We replace the value of x with domain,

when x = 0

y = -2 × 0 + 3

y = 3

When x = 2

y = -2 × 2 + 3

y = -1

When x = -6

y = -2 × -6 + 3

y= 12 + 3

y = 15

Answer:

y = 0.02

Step-by-step explanation:

You can see in the table that there is only one value which represents only y, (0, 0.02) since x is 0.

Hope this helps and stay safe, happy, and healthy, thank you :) !!

Answer:

The numbers that work are: -15, 5, 3.5, and 4 3/4

Step-by-step explanation:

Subtract 5 from both sides of the equation. Which will give you 15≥3x. Then you divide both sides by 3 which will give you 5≥x.

20≥5+3x

-5        -5

15≥ 3x

÷ 3      ÷ 3

5 ≥ x

Answer:

y = 8

x = 4

Step-by-step explanation:

This is a special right triangle with angle measures of 90 60 30 and the side lengths are represented by a - a√3 - 2a

The side length that sees angle measure 30 is a

The side length that sees angle measure 60 is a√3

The side length that sees angle measure 90 is 2a

if the side length that sees angle measure 60 is given as 4√3 then that means a = 4

so x = 4 and 2x = 8

Answer:

189

Step-by-step explanation:

7 x 27 = 189

A product is the result of a multiplication problem.

27 * 7 = 189

Your answer: 189

Answer:

n = 4

im not good at explaining by text but i hope this helps

Step-by-step explanation:

3n - 8 = 4

you want the variable by itself so you will start with the number without the variable

3n - 8 = 4

next to the 8 is a - sign so it will is negative now it has to be the opposite

3n - 8 = 4

+8. +8

you cancel out the 8 and 4+8 is 12

now you have to do 12 ÷ 3 to get the variable by itself

12 ÷3 is 4

Answer:

Step-by-step explanation:

y=3|x|, shift right 8 units

y=3|x-8|, shift up 1 unit

y=3|x-8|+1

Answer:

Mia spent 68 dollars.

Step-by-step explanation:

The equation would be 2(13.50) + 4(10.25) = x

Solving for the first part, you get 27 for adult tickets and 41 for the children tickets. When you add the two values, you get 68.

Answer:

Should be A

Step-by-step explanation:

You going back 3 spaces but than having that three be divided by a positive so it's going to keep going because a negative will make a negative so that positive will be turned into a negative. -3 - 1.5 = -4.5

Answer:

The circumference is 87.96

Step-by-step explanation:

Multiply 2 and pi and 14 together and you will get this answer

Formula: C=2πr

Answer:

4 hours

Step-by-step explanation:

It is 4 hours because you do 36 divide by 12 which is 4, Then you do 4x1= 4

Answer:

2:3

Explanation:

Pack 48                          48/2 =24

Red= 24                      24/24 : 24 / 24

Black = 24                            1:1

----------------------------------------------------------------

Pack 48                        48/2 = 24    

Red= 16                     24 / 16 : 24 / 24

Black= 24                    

16:24

4:6

2:3

Answer: 15

Step-by-step explanation:

This is a right angle and right angles always add up to 90 degrees.

You would take away 30 from 90 which equals 60.

Then because it is 4x you would do the inverse and divide 60 by 4 to get x on its own.

60/4=15

Answer:

Option D) The opposite of 3 is -3. The absolute value of 3 is -3.

Step-by-step explanation:

On a number line, if you go three to the right from 0, you get 3. But if you go the same amount to the left of 0, you would get -3. I can't think of any other way to explain the opposite. The absolute value is usually the same number but the absolute value is usually the same number, but it's opposite.

I hope i explained that well and that you do well on your test!

Answer:

Step-by-step explanation:

because all the three laws are applicable for polygons

Answer:

D

Step-by-step explanation:

This equation is in factored form. Meaning you can find the x intercepts of the graph from it. All you need to do is find reverse the numbers inside the parentese. So if its negative, make it positive, if its positive, make it negative. By doing this, you should find that the x-intercepts of this graph are 2 and 3 and the donly graph with x-intercepts at these places is graph d.

Answer:

The answer is d

Answer:

25%

Step-by-step explanation:

30/40 = 0.75 = 75% paid

100-75 = 25% discount

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;

[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]

Substitute in the given values;

[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]

Solve;

[tex]\frac{10}{40}=\frac{percent}{100}[/tex]

Simplify,

[tex]\frac{1}{4}=\frac{percent}{100}[/tex]

Cross products,

[tex]100 = 4(percent)[/tex]

Inverse operations,

[tex]100=4(percent)\\/4\\\\25 = percent[/tex]
