P = 17
Step-by-step explanation:
3y – 2 = y + 4
3y -2 (+2) = y + 4 (+2)
3y = y + 6
3y (-y) = y (-y) + 6
2y = 6
2y / 2 = 6 / 2
Y = 3
PR = 3y – 2
PR = 3(3) – 2
PR = 9 – 2
PR = 7

Investors buy a studio apartment for $180,000 . Of this amount, they have a down payment of $36,000. Their down payment is what percent of the purchase price? What percent of the purchase price would a $9,000 down payment be?
Answers
Answer:
Step-by-step explanation:
From the question, we are informed that investors buy a studio apartment for $180,000 and that they have a down payment of $36,000. The percentage of the down payment on the purchase price will be:
= 36000/180000 × 100
= 1/5 × 100
= 20%
What percent of the purchase price would a $9,000 down payment be?
This will be:
= (9000 / 180000) × 100
= 0.05 × 100
= 5%
Answer:
20%
5%
Step-by-step explanation:
Price of a studio apartment = $180,000
Down payment = $36,000
Their down payment is what percent of the purchase price?
= Down payment / Price of a studio apartment × 100
= $36,000 / $180,000 × 100
= 0.2 × 100
= 20%
What percent of the purchase price would a $9,000 down payment be?
= Down payment / Price of a studio apartment × 100
= $9,000 / $180,000 × 100
= 0.05 × 100
= 5%

Martin would like to start training to run a marathon. The first week he runs a total of 15 miles. He would like to run 0.3 more miles each week than the week before. How far will Martin run the second week?
Answers
Answer: 15.3 miles
Step-by-step explanation:
From the question, we are informed that Martin would like to start training to run a marathon and that first week he runs a total of 15 miles.
We are further told that he would like to run 0.3 more miles each week than the week before. There, the number of miles that Martin will run the second week will be:
= 15 miles + 0.3 miles
= 15.3 miles

Answer:
Divide using synthetic division
Step-by-step explanation:
2x^2 − 10x − 202
2x^2 - 10x + 50 - 252/x-5
2x^2 + 10x + 298
2x^2 + 10x + 50 + 248/x-5
The Synthetic divison is (2x^(3) -2) ÷ (x-5) = 2x^(2) - 2x + 6.
What is synthetic division?Write the coefficients of the dividend in a row, placing the divisor to the extreme left of the row then Bring the first coefficient of the divisor down.
To Multiply the divisor by the number directly below it in the row and write the answer to the right of the number. Now Add the two numbers to the right of the divisor and write the answer below.
For the example given, the process is as;
(2x^3 - 2) ÷ (x - 5)
(x - 5) | 2 -10 14 -24
| -4 8 10 24
| 0 -2 6 0
| 0 0 0 0
Therefore, the quotient is 2x^(2) - 2x + 6

Two rectangular fields with identical shapes and areas are to be fenced side by side. The total area enclosed is 8 mmmm2 and the perimeter for all the fencing is 16 miles. Find the possible dimensions of one of the fields (2 possible answers).
Answers
Answer:
3 mi and [tex]\dfrac{4}{3}[/tex] mi, 1 mi and 4 mi
Step-by-step explanation:
Length of one of rectangles = x
Breadth of one of the rectangles = y
Total enclosed area = [tex]8\ \text{mi}^2[/tex]
Fence available = 16 miles
Total area is given by
[tex]2xy=8\\\Rightarrow y=\dfrac{4}{x}[/tex]
Perimeter of the fence
[tex]2\times 2x+3y=16\\\Rightarrow 4x+3y=16\\\Rightarrow 4x+3\dfrac{4}{x}=16\\\Rightarrow 4x+\dfrac{12}{x}=16\\\Rightarrow 4x^2-16x+12=0\\\Rightarrow x=\frac{-\left(-16\right)\pm \sqrt{\left(-16\right)^2-4\times \:4\times \:12}}{2\times \:4}\\\Rightarrow x=3,1[/tex]
If [tex]x=3[/tex]
[tex]y=\dfrac{4}{x}=\dfrac{4}{3}[/tex]
If [tex]x=1[/tex]
[tex]y=\dfrac{4}{x}=4[/tex]
The possible values of length and breadth are 3 mi and [tex]\dfrac{4}{3}[/tex] mi, 1 mi and 4 mi respectively.
A 2% solution of acid was mixed with a 12% solution to produce an 8% solution. The amount of 2% solutions is 2 liters less than the 12% solution. How much 2% solution and how much 12% solution were used to produce 10L of the 8% solution ?
Answers
Answer:
The number of liters of 2% solution of acid = x = 4 Liters
The number of liters of 12% solution = y = 6 Liters
Step-by-step explanation:
Let us represent
The number of liters of 2% solution of acid = x
The number of liters of 12% solution = y
The system of equations for the above question is given as:
x + y = 10L...... Equation 1
x = 10 - y
2% × x + 12% × y = 8% × 10L
0.02x + 0.12y = 0.8....... Equation 2
We substitute 10 - y for x in Equation 2
0.02(10 - y) + 0.12y = 0.8
0.2 - 0.02y + 0.12y = 0.8
Collect like terms
- 0.02y + 0.12y = 0.8 - 0.2
0.10y = 0.6
y = 0.6/0.10
y = 6 Liters = 6 L
Note that:
x = 10 - y
x = 10 - 6
x = 4 Liter= 4 L
Therefore:
The number of liters of 2% solution of acid = x = 4 Liters
The number of liters of 12% solution = y = 6 Liters

A fruitcake recipe calls for 2 1/3 cups of almonds and 1 3/4 cups of pecans. If Eliza would like to make 4 fruit cakes, then how many cups of nuts does she need?
Answers
Answer:
Almonds used for 4 fruitcake = 9 1/3
Pecans used for 4 fruitcake = 7 cups
Step-by-step explanation:
Recipe for 1 fruitcake:
Almonds = 2 1/3 cups
Pecans = 1 3/4 cups
If Eliza would like to make 4 fruit cakes, then how many cups of nuts does she need?
Recipe for 4 fruitcake:
Multiply each recipes by 4
Almonds = 2 1/3 cups × 4
= 7/3 × 4
= (7×4) / 3
= 28/3
= 9 1/3 cups
Almonds used for 4 fruitcake = 9 1/3
Pecans = 1 3/4 cups × 4
= 7/4 × 4
= (7×4) / 4
= 28 / 4
= 7 cups
Pecans used for 4 fruitcake = 7 cups
