Jerome ordered some CDs and DVDs online. He bought 2 CDs and 5 DVDs. He spent a total of $138.45.

Part 1: Write the equation for this word problem. Be sure to identify your variables.

Part 2: If each CD cost $14.25, solve the equation to find the cost of each DVD. Show your work.

Answers

Answer:gchckc

Step-by-step explanation:

let x be CDs and y be DVDs
2x + 5y = 138.45
plug in the cost of the CDs for x
2(14.25) + 5y = 138.45
multiply
28.50 + 5y = 138.45
subtract 28.50 from both sides to isolate y
5y = 109.95
divide both sides by 5 to isolate y
y = 21.99

Answer:

Angle O = 72°, Angle M = 18°, Angle N = 90°

Step-by-step explanation:

According to the angle sum theorem, all interior angles of a euclidean triangle always add up to 180°.

given 5(Angle M) = Angle N, and 4(Angle M) = Angle O, you can substitute these equations into the equation defined by this theorem, Angle M + Angle N + Angle O = 180°

. Angle M + 5(Angle M) + 4(Angle M) = 180°

10(Angle M) = 180°.

then you divide. Angle M = 18°

with this statement. you can substitute this into the other equations to get the other answers.

5(18°) = Angle N, 4(18°) = Angle O.

90° = Angle N, 72° = Angle O.

answer:
angle O=72, angle M =18, Angle N = 90

Kara and James both like to mix a little bit of milk with their eggs when they make scrambled eggs. Kara mixes ¾ of a tablespoon of milk with one egg. James mixes 1 ¼ tablespoons milk with two eggs. Is there a proportional relationship between Kara and James’ milk and egg amounts?

Answers

Answer:

"No, there is not a proportional relationship."

Step-by-step explanation:

"A proportional relationship is when 2 amounts have the same ratios.

The easiest way to see this is to put them into decimal form.

3/4 is equal to 0.75 (You can find this by dividing 3 and 4 in the calculator)

1 1/4 is equal to 1.25

Kara mixes every 0.75 with 1 egg.  

James mixes every 1.25 tablespoons with 2 eggs.

Divide 1.25 by 2 to find out how many tablespoons that James mixes with 1 egg.

1.25  tablespoons /2 = 0.625

2 eggs                   /2 = 1 egg  

Therefore, James mixes 0.625 tablespoons of milk with 1 egg.

They do not mix the same amount of tablespoons of milk for ever ONE egg,  meaning that they are not proportional."

Given f(x) = 4x − 6 and g(x) = f(2x),
write an equation for g.

g(x) = _______________________

Answers

Answer:

1 and 1/3

Step-by-step explanation:

Fx equals 4x-6

Add six to both sides

6 equals 4X

Divide both sides by 4

2/3 equals x

Then GX equals f (2x)

Two times 2/3 is 1 and 1/3

The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

We have been given that  f(x) = 4x − 6 and g(x) = f(2x), then;

We have to Add six to both sides;

f(x) = 4x − 6

6 = 4X

Now Divide both sides by 4;

2/3 =  x

Then G(X ) is equals to f (2x)

Now, 2( 2/3 ) =  1 /3

The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

Please mark me as the Brainliest.

Answer: 3/28

Step by Step Explanation:
To solve this equation, we do NOT need the same denominator.
And since both fractions are negative, we know the answer is going to be positive.
So we just multiply normally.

-1/4 • -3/7

We cannot cross cancel anything, so we just multiply across.

-1 • -3 = 3
-4 • -7 = 28

So our answer is 3/28.

Which of the following equations has a positive slope?
y= -x+0
y= x
y= -4

Answers

Answer: i say number 3

Step-by-step explanation:

because i pay attention in math class

The equation y = x has the positive slope.

What is Slope?

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Given three equations which are in the form of slope intercept form of the equation of a line.

Slope intercept form of a line is y = mx + d, where m is the value of the slope and d is the value of the y intercept.

y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.

Equations given are

y = -x + 0 ⇒ Slope = -1

y = x ⇒ Slope = 1

y = -4 ⇒ Slope = 0

So y = x has the slope equal to 1 which is positive.

Hence the equation y = x has the positive slope.

What is the value of n when 6n-14=3n+7

Answers

answer: n=7

work:

6n-14=3n+7

6n-14 (+14) = 3n+7 (+14)   add 14 to both sides

6n=3n+21

6n(-3n)=3n(-3n)+21    subtract 3 from both sides

3n=21

3n/3= 21/3    divide by 3 on both sides

n=7

Answer: n = 7

Step-by-step explanation; Simplifying

6n + -7 = 14 + 3n

Reorder the terms:

-7 + 6n = 14 + 3n

Solving

-7 + 6n = 14 + 3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-3n' to each side of the equation.

-7 + 6n + -3n = 14 + 3n + -3n

Combine like terms: 6n + -3n = 3n

-7 + 3n = 14 + 3n + -3n

Combine like terms: 3n + -3n = 0

-7 + 3n = 14 + 0

-7 + 3n = 14

Add '7' to each side of the equation.

-7 + 7 + 3n = 14 + 7

Combine like terms: -7 + 7 = 0

0 + 3n = 14 + 7

3n = 14 + 7

Combine like terms: 14 + 7 = 21

3n = 21

Divide each side by '3'.

n = 7

Simplifying

n = 7

two angles in a triangle have measures of 62 degrees and 15 degrees. What is the measure of the third angle.

A.92 degrees

B.47 degrees

C.77 degrees

D.103 degrees

Answers

Answer:

the answer is 103

Step-by-step explanation:62°+15°=77° degrees

Then it is 180° - 77° degrees

180°-77°=103°

The measure of the third angle of a given triangle is 103°.

Given that the measure of two angles is 62° and 15°.

We need to find the measure of the third angle.

What is the angle sum property of a triangle?

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.

Let the measure of the third angle be x.

Now,  62°+15°+x=180°

⇒x=180°-77°

⇒x=103°

Therefore, the measure of the third angle is 103°.
