Answer 1

Answer:

25-7

Step-by-step explanation:

"Substitute for": Replace x with ____

Since it is given that x = 25 -y, we can replace the x in 5x + y = 10 with 25 - y by the substitution property of equality.

Answer 2

Answer:

The expression to substitute for x is: 25-y, as said in the first equation

Step-by-step explanation:

Not sure if you need to solve for the variables, but here:

To find y:

Put 25-y in place of x.

You will get:

5(25-y) + y = 10

Use the Distributive Property and multiply 25 and y by 5:

125 - 5y + y = 10

Combine like terms (the y's):

125 - 4y = 10

Put like terms on the same side (move the 125 to the right side of the equal sign by subtracting 125 from both sides:

-4y = -115

Divide both sides by -4:

y = 28.75 (or 28-3/4)

To find x:

Substitute 28.75 for y in either equation.

First equation:

x= 25 - 28.75

x= -3.75

Second equation:

5x + 28.75 = 10

Subtract 28.75 from both sides:

5x = -18.75

Divide both sides by 5:

x = -3.75

The lengths of sides of the parallelogram are 71 inches and 51 inches. Hence, option (C) is correct.

What is parallelogram?

A unique variety of quadrilateral called parallelogram, a parallelogram has both pairs of its opposite sides parallel and equal.

Let sides of the parallelogram are a and b.

The perimeter of parallelogram  = 2(a+b)

Given that,

The perimeter of parallelogram = 244

implies that,

2(a+b) = 244

a+b = 122       (1)

Also, the difference of sides is 20 inches,

implies that,

a-b = 20       (2)

By solving equation (1) and (2),

a = 71 inches,

b = 51 inches.

The lengths of sides of the parallelogram are 71 inches and 51 inches.

Which of the following is something a lender will not consider when reviewing your loan application?
a collateral
b. family size
c. credit score
d. debt-to-Income (DTI) ratio

Answers

Answer:

B family size

Step-by-step explanation:

The lender will not consider family size when reviewing your loan application.

What is Loan application?

Loan applications could be declined for so many reasons. However, in a situation where an application is not granted, it is good to find out the reasons behind the decision so as to avoid repeating such in subsequent applications.

Another step to be taken after the denial of the application is to look for an alternative lender and make another application.

One may also need to improve on the application to avoid another denial this time around.

Since Lenders have different risk appetites and preferences. What one lender tells about your creditworthiness is not necessarily what another will. They may view your finances as well enough to apply.

Simplify the rational Expression

Answers

Answer:

[tex]\frac{x^2+2x}{x-3}[/tex]

Step-by-step explanation:

We need to factor out numerator and denominator in order to simplify the rational expression by cancelling  common factors.

Numerator :  x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)

Denominator (factoring by grouping):

x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)

Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:

x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)

If 6x-4 is 11 less than 25,what is the value of 9x

Answers

Answer:

Step-by-step explanation:

If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:

6x-4=25-11, what is the value of 9x?

Let's solve for x first by using the given information: 6x-4=25-11

1. 6x-4=25-11

2. 6x-4=14

3. (isolate x by adding 4 on both sides) 6x=18

4. x=3

The question asks for the value of 9x. Since we know x=3...

9x=9 times 3=27

9x=27

a homeowner has just installed a swimming pool with a capacity of 3.5 x 10⁴ gallons.of the pool is initially empty, how many hours will it take to fill it using only a garden hose that delivers 630 gallons of water per hour

Answers

Using proportions, it is found that it will take 55.6 hours to fill the poll.

What is a proportion?

A proportion is a fraction of total amount, and the measures are related using a rule of three.

In this problem, in one hour, 630 gallons of water are delivered. How many hours are going to take to deliver 3.5 x 10⁴ gallons = 35000 gallons?

The rule of three is:

1 hour - 630 gallons

x hours - 35000 gallons

Applying cross multiplication:

[tex]630x = 35000[/tex]

[tex]x = \frac{35000}{630}[/tex]

[tex]x = 55.5[/tex]

It will take 55.6 hours to fill the poll.

The hours it would take to fill the swimming pool is 55.6 hours.

What does division mean?

Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.

How many hours would it take to fill the swimming pool?

Number of hours = capacity of the swimming pool / capacity of the hose

3.5 x 10^4 / 630

35,000 / 650 = 55.6 hours
