4200. If the sale price is 5/6 of
the original Price . How much did
trey pay for the computer?

Answers

Answer:

3500

Step-by-step explanation:

To find a fraction of something just keep in mind that "of" means to multiply (when dealing with fractions and percents).  In this case we want to know what 5/6 of 4200 is.  So do (5/6)*4200 and that equal 3500.

6(6v +6) - 5 = 1 + 6v

Need answer with explaination

Answers

Answer:

v=-1

Step-by-Step Explanation:

Answer:

[tex]v=-1[/tex]

Step-by-step explanation:

[tex]6\left(6v+6\right)-5=1+6v[/tex]

Use the distributive property to multiply 6 by 6v+6:

[tex]36v+36-5=1+6v[/tex]

Subtract 5 from 36 = 31

[tex]36v+31=1+6v[/tex]

Subtract 6v from both sides:

[tex]36v+31-6v=1[/tex]

Combine like terms:

[tex]36v[/tex] and [tex]-6v[/tex] [tex]=30v[/tex]

[tex]30v+31=1[/tex]

Subtract 31 from both sides:

[tex]30v=-30[/tex]

Divide both sides by 30:

[tex]\cfrac{30v}{30}=\cfrac{-30}{30}[/tex]

[tex]v=-1[/tex]

A number is 6 times another number and their sum is 28.what are the two numbers

Answers

Answer:  Let the 2 numbers be x and  

sum of two numbers is 28....Eq 1:  x + y = 28

sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2:  6x + 3y = 105

Rearrange Eq 1 to solve for x.

x + y = 28

x = 28 - y  --> Substitute into Eq 2, you get

6(28 - y) + 3y = 105

168 - 6y + 3y = 105

-3y = -63

y = -63 / -3 = 21

Now solve for x using Eq 1.

x = 28 - y = 28 - 21 = 7

Emerson purchased a game that was on sale for 18% off. The sales tax in his county is 8%. Let y represent the original price of the game. Write an expression that can be used to determine the final cost of the game.

Answers

Using decimal multipliers, it is found that the expression that can be used to determine the final cost of the game is given by:

[tex]C = 0.8856y[/tex]

Decimal multipliers:The equivalent multiplier for an increase of a% is given by: [tex]\frac{100 + a}{100}[/tex]The equivalent multiplier for an decrease of a% is given by: [tex]\frac{100 - a}{100}[/tex]

In this problem:

Purchase for 18% off, hence decrease of 18%, that is, [tex]\frac{100 - 18}{100} = 0.82[/tex].Sales tax of 8%, hence, an increase of 8%, that is, [tex]\frac{100 + 8}{100} = 1.08[/tex].

Applying both multipliers, the expression is:

[tex]C = y(0.82)(1.08) = 0.8856y[/tex]

Answers

Answer:

n = 3.16 units; p = 5 units

Step-by-step explanation:

to find the length of the lines you need to use the pythagorean  theorem or a^2 + b^2 = c^2

in this case a is x, b is y, and c is the length

so for n it is:

1^2 + 3^2 = c^2 -->

1 + 9 = c^2 -->

10 = c^2

c = 3.16227766 or about 3.16 (this is n's length)

for p it is:

3^2 + 4^2 = c^2 -->

9 + 16 = c^2 -->

25 = c^2 -->

c = 5 (this is p's length)

Answer:

x = 32

Step-by-step explanation:

The angle above 72° is 108° because they are supplementary angles, meaning they add up to 180°. Then we can set the equation 108° = (3x + 12)° because they are alternate interior angles, meaning that they are the same. So then we just solve for x.

108 = (3x + 12)

108 - 12 = 3x

96 = 3x

96 / 3 = x

32 = x

Your boss sends you to the hardware store to buy tie down rope. He tells you to buy the best deal. What is the savings per unit between the best deal and worst deal?

A) $50.00

B) $25.00

C) 5 cents

D) 14 cents

Answers

Answer:

D. 14 cents

Step-by-step explanation:

At 10 feet for $7, that is 70 cents for every foot

At 20 feet for $13, that is 65 cents for every foot

At 50 feet for $28, that is 56 cents for every foot

At 100 feet for $57.50, that is 58 cents (rounded) for every foot

The best deal is 50 feet at 56 cents

The worst deal is 10 feet at 70 cents

So we do 70 - 56 = 14

So the answer is the savings per unit between the best deal and worst deal is 14 cents
