The perimeter of a triangle is 16x−6. If two sides measure 3x+2 and 4x−9, then how long is the third side?

Answers

Answer 1
Answer:

Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,

we know,

\hookrightarrow \: y + 3x + 2 + 4x - 9 = 16x - 6

\hookrightarrow \: y + 7x - 7 = 16x - 6

\hookrightarrow \: y = 16x - 6 - 7x + 7

\hookrightarrow \: y = 6x + 1

hence, measure of the third side is 6x + 1

“You can earn money by tutoring for $8 per hour and by walking dogs for $7.50 per hour. You have 15 h available to work. What is the greatest number of hours you can spend walking dogs and still make at least $115?”I need help

Answers

1.       Given numbers:
=> $8 per hour by tutoring
=> $7.50 per hour by walking the dogs
=> You have 15 hours available
=> You need to make atleast $115 in walking the dogs.

let’s assign a variable to use.
Let a = tutoring
Let b = walking the dogs
=> a + b = 15
=> 8a + 7.5b = 115
=> 8a + 7.5(15 - a) = 115
=> 8a = 112.5 = 115
=> 8a = 115 – 112.5
=> 8a = 2.5
=> 8a / 8 = 2.5 / 8
=> a = 0.3125
=> b = 15 – 0.3125
=> b = 14.6875



Answer:

14.6875

Game stop is having a 15% off sale. If the game rocket league is $40 and the sales tax rate is 6.25%, how much would you pay after the discount and sales tax is applied?

Answers

The buyer will pay $36.125 after the discount and sales tax

Step-by-step explanation:

Given

Price of Rocket league = $40

Discount = 15%

Sales tax = 6.25%

First of all we have to find the discounted price

So,

Discount = 15\%\ of\ 40\n= 0.15*40\n=6

The discount is $6.

The discounted price will be:

Discounted\ price = price - discount\n= 40-6\n= \$34

The sales tax will be applied on this discounted price now.

So,

Sales\ tax = 6.25\%\ of\ 34\n= 0.0625 * 34\n=2.125

So the total price of Rocket league after discount and sales tax will be:

Final\ price = Discounted\ price + Sales\ tax\n= 34+2.125\n=36.125

Hence,

The buyer will pay $36.125 after the discount and sales tax

Answer:

$36.13

Step-by-step explanation:

Given that the price of the game rocket league is $40.

There is a 15% discount:

discount = 0.15 x $40 = $6

Therefore price after discount = 40 - 6 = $34

There is a sales tax of 6.25%:

sales tax = 0.0625 x $34 = $2.125

Therefore price after applying sales tax = 34 + 2.125 = $36.125

$36.125 ≈ $36.13

Answers

Argh! My answer was erased!

We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a

Simplify
3/4 = a

In meters, each rope segment is 3/4m long.  But, we don't want meters.  We want centimeters.

100 cm = 1 m

3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x

300/4 = x
75 = x

Each segment of rope is 75 cm long.
The rope needs to be cut into 20 pieces, so 15/20, this will give you 3/4 of a meter per piece. Multiply 100 (100 cm in a meter), .75*100= 75 centimeters in a piece...
