The number of hours Hannah practices each week is 3 hours less than twice the number of hours Darcy practices. If n represents the number of hours Darcy practices, which expression below represents the number of hours Hannah practices?

Answer:

Your supposed to cancel out 12 on both sides so u subtract 12 on both sides so the equation would be

-3x= -52

Step-by-step explanation:

Answer:

17.3333

Step-by-step explanation:

-3x+12=-40

3x=-40-12

3x=-52

x=52÷3

x=17.3333

Answer:

Step-by-step explanation:

Answer:

f(x)= -1/2(1-x)^2

replacing x with -5 since -5 was given as the function

f(-5)=-1/2(1-5)^2

according to bodmas we solve what is in the bracket first

f(-5)=-1/2(-4)^2

f(-5)=-1/2(16)

-1/2*16/1

-16/2=-8

Answer:

Answer:

x = 3.5

Step-by-step explanation:

Distribute the 4

24x - 38 = 46

Add 38 to both sides

24x = 84

divide by 24

Step-by-step explanation:

From the figure attached,

Given:

Lines AB and CD are intersecting each other at a point E.

To prove:

∠ACB ≅ ∠DEB

             Statements                                 Reasons

1). ∠AEC + ∠BEC = 180°                        1). Linear pair theorem

2). ∠DEB + ∠BEC = 180°                       2). Linear pair theorem

3). ∠AEC + ∠BEC = ∠DEB + ∠BEC      3). Transitive property of equality

4). ∠AEC = ∠DEB                                  4). Subtraction property of equality

Answer:

Here is the explanation of how I was taught to do it :)

Step-by-step explanation: In its easiest form, an A=4, B=3, C=2, D=1, F=0.

If the class is 2 credit.......Multiply each numeric grade value by the number of credits the course was worth

Add these numbers together

Divide 45 by the total number of credits you took, in this example,13.

Your Weighted by Credit Hour GPA = 3.46

It depends on your school. Sorry this was not the most clear, I was taught like 2 years ago, and now I kinda forgot but hopefully this helps a lil dont get mad :)

The answer would be t = 8p + 72

Answer:

No solutions

Step-by-step explanation:

–2(3x – 1) = –6x – 1

First distribute the left side

-6x + 2 = -6x - 1

Add 1 to both sides

-6x + 3 = -6x

Add 6x to both sides

3 = 0

This equation is not true because 3 does NOT equal 0. Therefor, this equation has no solutions.

Answer:

there is no solution

Step-by-step explanation:

There are no values of x that make the equation true.

Answer: The answer is: 83°

Step-by-step explanation

Here,

the sum of the total internal angle of a triangle is equal to 180°.

So,

8x+12+10x+23+55-3x=180

solving this equation we get, x=6°

finally,

the angle at George's position=10x+23=10*6+23=83°

Answer:

Step-by-step explanation:

Given the function;

g(x) = x^2 - x

We are to find g(-9)

g(-9) = (-9)² - 9

g(-9) = 81 - 9

g(-9) = 72

hence the value of g(-9) is 72

Answer:

$162.50 per month for the next 4 years

Step-by-step explanation:

Here are the options to this question :

Save $270.83 per month for the next 4 years

Save $162.50 per month for the next 4 years

Save $650.00 per month for the next 4 years

Save $108.33 per month for the next 4 years

If Devon's parents would give him $5,200 for his first year of tuition, Devon needs to save a minimum of :

$13,000 - $5,200 = $7,800

If he saves per month for the next four months, he would save 48 times ( 12 months in a year multiplied by 4 years)

The minimum he should save per month = $7800 / 48 = $162.50

Answer:

113.0

Step-by-step explanation:

:)

The volume of a sphere with a radius of 3 cm is  14.3 cm³.

In geometry, a sphere is a three-dimensional solid figure, which is round in shape.

The surface area is 4πr².

The volume is (4/3)πr³.

The diameter is 2×radius of the sphere.

We know a glope is in the form of a sphere.

We also know that the volume of a sphere is (4/3)πr³.

Therefore, The volume of a sphere with a diameter 3 cm Or a radius of

(3/2) cm has a volume,

= (4/3)π(3/2)³ cm³.

= 14.3 cm³.

Answer:

y=2/7x-4

Step-by-step explanation:

Write in Slope intercept form

y=mx+b

m = slope

b = y intercept

x = x intercept

y = (0,-4)

So,

y = 2/7x+(-4)   substitute

y = 2/7x-4
