What is the length of XY?

Answer:

x ≥ - 3

Step-by-step explanation:

Step 1:

- 7x - 13 ≥ 8       Equation

Step 2:

- 7x ≥ 21      Add 13 on both sides

Step 3:

x ≥ 21 ÷ - 7      Divide

Answer:

x ≥ - 3

Hope This Helps :)

Answer:     x≤−3

Step-by-step explanation:

So first you  -7*x-13-(8)≥0

then you are supposed to pull out like the factors  -7x - 21  =   -7 • (x + 3)

then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got  x ≤ -3 So I really hoped this helped :)

Answer:

B. 171.74 cm²

Step-by-step explanation:

Area of a sector = [tex] \frac{\theta}{360} \times \pi r^2 [/tex].

Where,

[tex] \theta = 260 [/tex]

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector = [tex] \frac{260}{360} \times \pi 8.7^2 [/tex]

Area of sector = [tex] \frac{260 \times \pi 75.69}{360} [/tex]

Area of sector = 171.74 cm² (approximated)

Answer:

B. 171.69 cm²

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

Since C represents the cost, and Allie's parents are willing to spend $300 for the party, our equation will now look like this:

300=5p+215

we are trying to find out how many people will able to attend

300=5p+215

-215        -215

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

85 =  5p

divide by 5 on both sides to undo the multiplication (5p)

300=5p+215

-215        -215

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

85 =  5p

÷5 =  ÷5

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

17  = p

So, p (number of people attending) would be 17 :)

hope this helps!

♡ The Explanation/Step-By-Step ♡

-  -4(-3n - 8) = 104

Divide both sides by -4!

-4(-3n - 8) over -4 = 104/-4

Simplify!

-3n - 8 = -26

Add 8 to both sides!

-3n - 8 + 8 = -26 + 8

Simplify!

-3n = -18

Divide both sides by -3!

-3n/-3 = -18/-3

Simplify!

n = 6

Answer:

x = ±6

General Formulas and Concepts:

Pre-Algebra

Algebra II

Step-by-step explanation:

Step 1: Define

-x² = -36

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

Here we see that both -6 and 6 do indeed work as solutions.

∴ x = ±6 are both solutions to the equation.

Answer:

1) Measure angle QWT and TWX are complementary because their measures add up to 90 degrees.

2) Both measure angles add up to 90 degrees because they're complementary.

3) Angle QWT = 2x and angle TWX = x + 6, and since angles QWT + TWX = 90 then 2x + x + 6 = 90.

4) (Made up?:) Angle measure QWX = 90. The quarter-turn, or the small square, indicates that the angle is 90 degrees.

5) (?)

6) x = 28 because it fulfills the equation, 2x + x + 6 = 90, or 3x + 6 = 90. 90 - 6 is 84, and 84/3 is 28.

Answer:

B

Step-by-step explanation:

Based on the amount that Sam saves and his living expenses, the amount he needs to save and the length of time it will take him to do so is B. 5,136; Approximately 24 months.

= Fixed essential expenses + Variable essential expenses

= 1,292 + 420

= $1,712

Sam needs to save three times his expenses:

= 1,712 x 3

= $5,136

= Amount to be saved / Amount saved monthly

= 5,136 / 210

= 24 months approximately.

________________________________________________________

The question is:

Using his essential expenses as a guideline, how much will Sammy need to save if he wants to have 3 times the amount of his living expenses in the bank as part of his emergency savings. How long will it take him to achieve his goal?

a. $1,712; approximately 8 months

b. $5,136; approximately 24 months

c. $6,486; approximately 30 months

d. $2,162; approximately 6 months

Answer:

{x,y}={31,4}

Step-by-step explanation:

x-8y = -1  x-6y = 7

Answer:

first we find the value of 'y' so

x-8y=-10+8y

x=-10+8y

-2(-10+8y)-6y=-24

20-16y-6y=-24

20-22y=-24-20

-22y=-44

y=2

then also we can find the value of 'x'

-2x-6y=-24

2x-6(2)=-24

2x-12= -24

2x= -24+12

x= -12

Answer:

x= 13

Step-by-step explanation:

3x-4+20= 55

combine like terms:

3x+16= 55

subtract 16 from both sides:

3x = 39

divide 3 to both sides:

x= 13

Answer:

I got 5^10 x 2^14 x 3

Step-by-step explanation:

1. Do a tree to find 480 as a product of its prime factors

2. You should get 480= 5x2x3x2x2x2x2

3. 10 expressed as a product of its prime factors is 5x2

4. so 10^9 expressed as a product of its prime factors would be

5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

5. You can then write out 480x10^9 as a product of its prime factors

5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

6. change this to use powers

5^10 x 2^14 x 3

N = 5^(10) × 2^(14) × 3

This is about prime factors

By definition, a prime factor is a factor of a number and that factor is also a prime number.

A prime number is one that is divisible by only itself and 1.

The number we have is; 480 × 10^(9)

Now, let's list the prime factors or 480 and they are;

2, 3, 5

Now, using these prime factors alone to get 480, we have;

5 × 3 × 2 × 2 × 2 × 2 × 2 = 480

In powers, gives;

5 × 3 × 2^(5)

Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;

(5 × 2)^(9)

Expanding this gives; 5^(9) × 2^(9) = 10^(9)

Thus;

480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)

This gives;

5^(10) × 2^(14) × 3

Step-by-step explanation:

What the shorthand is telling you is wherever you see an x on the right, you put in -8

f(x) = 6(1- x)

f(-8) = 6(1 - - 8)

f(-8) = 6(1+8)

f(-8) = 6*9

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be x

The number when decreased by 9 , the result is 24

So , x - 9 = 24

Adding 9 on both sides , we get

x = 33

Hence , the number is 33

The value of ∠BAD would be as follows:

D). 63

Given that,

The measure of ∠ABC [tex]= 114[/tex]

We know that,

BD bisects the ║gm ABCD

So,

∠ABD [tex]= 57[/tex]

Since opposite angles of a ║gm give equal

∠ABC = ∠ADC

So,

∠ ADB [tex]= 57[/tex]

Since the sum of all the angles of a ║gm is 360.

∠BAD can be found using this.
