Solve for x!!!!!!! Plzzzz

Answer:

Step-by-step explanation:

20%

Answer:

The correct answer is 20.0% increase.

Step-by-step explanation:

In this situation, you would need to find how to find the percentage of change.

Therefore, you will need to first use subtraction, division and then multiplication to justify your answer.

--

First, find out how much the original number increased by.

[tex]420-350=70[/tex]

Next, divide the 70 with the original number, which is 350.

[tex]7[/tex] ÷ [tex]350=0.2[/tex]

Finally, to turn your decimal into a whole number, multiply by 100.

[tex]0.2[/tex] × [tex]100=20[/tex]

--

Remember to add the percent (%) symbol after receiving your final product.

x² - 3x ≤ 54 m²

Step-by-step explanation:

Step-by-step explanation:

and ? what do we need to do with this ?

compress/simplify this ?

if that is true :

(x+3)(x²-3x+9)-(54+x³)

x³ - 3x² + 9x + 3x² - 9x + 27 - 54 - x³ = -27

Step-by-step explanation:

7 5/6 is 7.833333333333333333333

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Answer:

x+9=18-2x

-x         -x

9=18-3x

-18-18

-9=-3x

-3   -3

3=x

x=3  

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable and solve for x for the question “ x + 9 = 18 + -2x”.

Hope this helps :)

Answer:

see explanation

Step-by-step explanation:

f(x) = [tex]\frac{2x-5}{x-4}[/tex]

The denominator cannot equal zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be

x - 4 = 0 ⇒ x = 4 ← excluded value

Domain is x ∈ R , x ≠ 4

Answer:

D.

Step-by-step explanation:

7h is the amount of money Jim makes per hour. You can find the amount of money Susan makes by dividing the amount she made to the hours:

15/2 = 7.50

Susan charges $7.50, which is higher than Jim's hourly rate. which is the correct answer would be a statement (D)

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

To find the hourly rate for Jim, you can plug in different values for h (the number of hours) in the equation t = 7h + 10 and solve for t (the total). For example, if h = 1, then t = 7(1) + 10 = 17. This means that if Jim babysits for 1 hour, he charges $17.

If you divide the total amount that Jim charges by the number of hours he works, you get his hourly rate. In this case, the hourly rate is t/h = 17/1 = $17/hour.

To find Susan's hourly rate, you can divide the total amount that she charges by the number of hours she works. For example, if Susan babysits for 2 hours, she charges $15, so her hourly rate is $15/2 = $7.50/hour. If Susan babysits for 4 hours, she charges $30, so her hourly rate is $30/4 = $7.50/hour.

Since Susan charges $7.50/hour, which is higher than Jim's hourly rate of $17/hour, the correct statement is D.) Susan charges $7.50, which is higher than Jim's hourly rate.

Answer:

B

Step-by-step explanation:

DE is the line that has two ticks through it - the same as FG

the next line goes through the hypotenuse and it is EG for the first triangle and GE for the second

the last line goes through the line with one tick: GD and EF; the points G and D are at the ends of the first part of the congruence statement. the points E and F are also at the ends of their congruence statements

thus the answer is B

Answer:

$108.79

Step-by-step explanation:

49.45÷5=9.89

9.89=the cost for 1 video game

9.89×11=108.79

(11=the used video games)

The answer would be $108.79 for 11 used video games.

Answer:

k=4

Step-by-step explanation:

So we have the graphs of f(x) and g(x).

And we know that g(x) is defined as  f(kx), where k is some constant.

First, from the graph we can note two points:

For g(x), we have the point (1,10) and for f(x), we have the point  (4,10).

ok now can you give me brainlest

Answer:

Weathering

Step-by-step explanation:

Weathering is the physical and chemical breakdown of rock at the earth's surface.  The physical breakdown of rock involves breaking rock down into smaller pieces through mechanical weathering processes. These processes include abrasion, frost wedging, pressure release (unloading), and organic activity.

Answer: I would like to say this is the act of weathering

130%

Step-by-step explanation:

(299 - 130)/130 × 100%

= 169/130 × 100%

= 169/13 × 10%

= 13 × 10%

= 130%

Answer:

x=5

Step-by-step explanation:

x^2+25-10x = x^2-25

-x^2               -x^2

25-10x = -25

-25        -25

-10x = -50

x=5

lets check

(5-5)^2 = 5^2-25

0^2 = 25-25

0 = 0

Answer:

x = 5

Step-by-step explanation:

(x - 5)^2 = (x - 5) (x - 5) =

x^2 -10x + 25 = x^2 - 25

x^2 - x^2 - 10x + 25 = - 25 (x^2 - x^2 = 0)

- 10x + 25 = - 25

- 10x = - 25 - 25

x = - 50/- 10

x = 5

Answer:

The expression p−0.45p can be simplified to  0.55 p.

This means Phyllis can find the new price of a hat by finding  55 % of the original price.

Step-by-step explanation:

The given expression describes that the price of the Hat would be 55% of the original price.

Given that,
Hats are on sale for 45% off. Phyllis uses the expression p−0.45p to find the new price of a hat that originally cost p dollars.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Given expression,
= p−0.45p
Simplify further,
= 0.55p
The above expression implies that the outcome is 55% of p, where p is the original price of the Hats.

Thus, the given expression describes that the price of the Hat would be 55% of the original price.

Answer:

There are 12 players

Step-by-step explanation:

6 x 2 = 12

Answer:

1) Divide the numerator by the denominator to get 0.6

2) Divide the numerator by the denominator to get 0.7

3) Divide the numerator by the denominator to get 0.25

4) Place 55 over 100, since this number is in the hundredths place, and then divide it (55 ÷ 100). Your answer is 11/20 .

5) Place 6 over 10, since this number is in the tenths place, and then divide it

(6 ÷ 10 = 3/5). Next multiply the whole number (10) by the denominator (5) and then add the numerator (3) to get 53. You now have 53/5 which is the improper form, or 10 3/5 which is the mixed number form.

6) Place 856 over 1,000 , since this is in the thousandths place, and then divide it

(856 ÷ 1,000). Your answer is 107/125 .

7) 0.05, 0.5, 4/5

Answer:

Hey, so it's actually pretty simple I'll try my best to explain it properly!

Step-by-step explanation:

So for the first blue circle the line that goes to the middle that's the radius. And to solve the area you need to know the radius. The formula to solve the area is A = [tex]\pi[/tex] [tex]r^{2}[/tex] so what we would do its 3.14 times 6 times 6 or 3.14 times 36 which would give us the area! Now for circumference, the equation for that is C = 2[tex]\pi r^{2}[/tex] which would look like 2 times 3.14 times 6 times 6 or 2 times 3.14 times 36 and that would give you the circumference.
