How many solutions does the equation 4y + 7 = 5 + 2 + 4y have?
A. One
B. Two
C. None
D. Infinitely many

Answers

Answer 1

Answer:

D. infinitely many

Step-by-step explanation:

5+2 = 7 so 4y + 7 = 5 + 2 + 4y just equals 4y + 7=4y + 7 and any value of y is true in that equation.

Answer 2

Answer:

D :)

Step-by-step explanation:

Add 55 and 22.

4y+7=7+4y4y+7=7+4y

Move all terms containing yy to the left side of the equation.

Subtract 4y4y from both sides of the equation.

4y+7−4y=74y+7-4y=7

Combine the opposite terms in

Subtract 4y4y from 4y4y.

0+7=70+7=7

Add 00 and 77.

7=77=7

Since 7=77=7, the equation will always be true for any value of yy.

All real numbers

The result can be shown in multiple forms.

x = 16±2√94 over 3

Step-by-step explanation:

Move terms to the left side.

0 = -6x² + 64x + 80

- ( -6x²+64+80) = 0

Distribute

6x² - 64x - 80 = 0

Common factor

6x² - 64x - 80 = 0

2 (3x²-32x--40) = 0

Divide both sides by the same factor

You lend out S5500 at 10% compounded monthly. If the debt is repaid in 18 months, what is the total owed at the time of repayment?

Answers

Answer:

$6386.1140

Step-by-step explanation:

Using the compound interest formula :

A = P(1 + r/n) ^nt

P 5500 ; rate, r = 10% = 0.10 ; t = 18 months = 18/12 = 1.5 years,

Compounding times per period = 12 (monthly)

A = 5500(1 + 0.1/12)^12*1.5

A = 5500(1 + 0.0083333)^18

A = 5500(1.0083333)^18

A = 5500 * 1.1611116

A = 6386.1140

Hence, amount to be repaid = $6386.1140

divide using long division

Answers

When 392,196 is divided by 87, the answer obtained using long division is 4,508.

What does math's long division mean?

The mathematical procedure for splitting big numbers into several smaller groups or sections is known as long division. The dividend is the number we divide into smaller groups, while the divisor is the number through which we divide. Difficulty difficulty can be solved by breaking it down into manageable parts.

According to the given information:

Dividend : 392,196

Divisor: 87 (number that divides)

39 / 87 = 0

392 / 87 = 4 (87x 4 = 348) - 4 is the first digit of the result

392 - 348 = 44 (remainder)

441 (next digit is one) / 87 = 5 (87x 5= 435) - 5 is the second digit

441-435 = 6 (remainder)

69 / 87 = not possible so add a 0, which is the third digit

696 / 87 = 8 (87x 8 = 696)

696- 696 = 0 (not remainder)

When 392,196 is divided by 87, the answer obtained using long division is 4,508.

A carpet, measuring 4m by 2. 5 m, cost $86. Find the cost of a carpet of the same quality, measuring 5m by 3m. ​

Answers

The cost of a carpet of the same quality, measuring 5m by 3m is $129.

We can use the unitary method to solve this problem. The unitary method is a technique used for solving a problem by first finding the value of a single unit, and finding the necessary value by multiplying the single unit value.

In this question, it is given that a carpet measuring 4m × 2.5m costs $86. That means the 10m² area of carpet costs $86 if we divide 10 by both the cost and area of the carpet we will find that, 1 m² area of carpet will cost $8.6. So the cost of a carpet of 5m × 3m will be the area of the carpet multiplied by the cost of the carpet per 1 m² i.e, 15m² of carpet will cost $8.6 × 15 which is equal to $129.

As the x-value decreases the y-value decreases for x < 0

As the x-value increases the y-value decreases for x > 0

How many ounces of a 28% alcohol solution and a 40% alcohol solution must be combined to obtain 51 ounces of a 32% solution?

Answers

Answer:

Number of ounces of 28% alcohol = x = 34 ounces

Number of ounces of 40% alcohol = y = 17 ounces

Step-by-step explanation:

Let us represent the

Number of ounces of 28% alcohol = x

Number of ounces of 40% alcohol = y

Our system of equations =

x + y = 51 ..... Equation 1

x = 51 - y

28% × x + 40% × y = 32% × 51

0.28x + 0.4y = 16.32......Equation 2

We substitute 51 - y for x

0.28(51 - y) + 0.4y = 16.32

14.28 - 0.28y + 0.4y = 16.32

- 0.28y + 0.4y = 16.32 - 14.28

0.12y = 2.04

y = 2.04/0.12

y = 17

Solving for x

x = 51 - y

x = 51 - 17

x = 34

Therefore,

Number of ounces of 28% alcohol = x = 34 ounces

Number of ounces of 40% alcohol = y = 17 ounces

7x-2y=10 slope intercept form

Answers

Answer:

7/2

Step-by-step explanation:

7x – 2y = 10

using ( y = mx + b) as our guideline

where m is the slope

7x – 2y = 10

subtract 7x from both sides

7x – 7x – 2y = 10 – 7x

–2y = 10x – 7x

when arranged in slope form

–2y = –7x + 10

divide both sides by (–2) to get y

[tex] \frac{ \\ - 2y}{ - 2} = \frac{ - 7x}{ - 2} + \frac{10}{ - 2} [/tex]

The price of a notebook has risen to $3.80 today. Yesterday's price was $3.30 . Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answers

The percentage increase in the price of the notebook is 15%.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100.

The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Finding the increase in the price of the notebook:

$3.80 - $3.30 = $0.50

Dividing the increase by the original amount:

0.50 / 3.30 = 0.1515

To change to a percent multiply by 100 and round off to significant numbers:

0.1515 *100 = 15.15% or, 15%.

Thus, the percentage increase in the price of the notebook is 15%.
