Solve for x. Round to the nearest tenth, if necessary.

In this rule, we have to find the value of any of the variables either first or second and substitute its value in the other equation.

It is best to use the substitution method when equations are either given in form or can be gain into the form of x = ay + b and y = mx + n.

A procedure to answer a system of linear equations in more than two variables algebraically is the substitution method. In this process, we find the value of any one of the variables by alienating it on one side and taking every other term on the other side of the equation.

Then we substitute that first value in the second equation.

The substitution method is one of the algebraic processes to answer simultaneous linear equations. It implies substituting the value of any one of the variables from one equation into the other equation.

And at last, we can put the value of y in any of the given equations to find x.

On solving the provided question,  annual rate is 2% while doing calculations through simple interest.

Borrowers must pay simple interest to lenders as a fee for a loan. Compound interest is not taken into account while calculating it; just the principal is used. Simple interest is applicable to all loans. It is also the form of interest that banks give their customers on their savings accounts. Simple interest can be calculated using a simple formula. Simply multiply the loan's principal by the interest rate and the period to get the total. Although some mortgages employ this calculation approach, this type of interest typically relates to auto loans or short-term loans.

Let the annual rate be x%

Principal Amount (p)= $600

Annual Rate (r) = x % (Assumed)

Time (t) = 5 years

Simple Interest (I) = $60

Use the simple interest formula given below:

SI = p×r×t/100

r = 60 ×100/600× 5

r = 2%

Thus, the annual rate of interest is 2 %.

Question:

April took out a $600 loan from the bank. At the end of 5 years, she pays back the principal, plus $60 simple interest. What was the interest rate? Enter your answer in the box.

a) Melissa's monthly payment for the promissory note is $133.10.

b) The total monthly payment amounts to $6,388.80.

c) The total finance charge is $388.80, which is the difference between the total payment and the promissory note amount.

The monthly payment represents the equal periodic payment made to settle the loan and the finance charge.

Using an online finance calculator, we can compute the monthly payment, total payments, and finance charges.

N (# of periods) = 48 months (4 years x 12)

I/Y (Interest per year) = 3.11%

PV (Present Value) = $6,000

FV (Future Value) = $0

Results:

PMT (Monthly Payment) = $133.10

Sum of all periodic payments (Total Payments) = $6,388.80

The minimum and maximum possible volume for a rectangular right prism are 1221.875 and 1603.125 cubic inches.

In this problem we must determine the minimum possible and maximum possible volumes for a rectangular right prism, whose volume formula including length uncertainties is shown below:

V = (w ± Δw) · (l ± Δl) · (h ± Δh)

Where:

Please notice that minimum possible volume is found when all "±" operators are replaced by "-" operators and that maximum possible volume is found when all "±" are replace by "+" operators. Given that statement does not mention the value of every length uncertainty, we assume that Δw = Δl = Δh = 0.5 in.

If we know that w = 12 in, l = 13 in, h = 9 in and Δw = Δl = Δh = 0.5 in, then the minimum and maximum possible volumes are:

Minimum possible volume

V = (12 in - 0.5 in) · (13 in - 0.5 in) · (9 in - 0.5 in)

V = (11.5 in) · (12.5 in) · (8.5 in)

V = 1221.875 in³

Maximum possible volume

V = (12 in + 0.5 in) · (13 in + 0.5 in) · (9 in + 0.5 in)

V = (12.5 in) · (13.5 in) · (9.5 in)

V = 1603.125 in³

Answer: 6/7 / 2/9 = 3/1 or 3 ✅

PLEASEEEE GIVE BRANLIEST

Step-by-step explanation:

To divide two fractions, you can invert the second one (the one being divided by) and then multiply the two fractions.

So:

(6/7) / (2/9) = (6/7) * (9/2)

To multiply the fractions, you just multiply the numerators together and multiply the denominators together.

(6/7) * (9/2) = (69)/(72)

= 54/14

So the final answer is 54/14.

You can also simplify the fraction by dividing the numerator and denominator by their greatest common factor.

54/14 = 3/1

So the final answer is 3/1 which is 3.

Answer: All Real Numbers Except "-8" (R - {-8})

Step-by-step explanation:

The domain of a function is all possible x values that the function can be defined with.

This means that if a value does not create any indeterminate situation, we can consider this value is in the domain of a function.

For this function, "-8" is not in the domain of the function because the denominator of a rational fraction cannot be zero in any case. This creates an indeterminate situation, therefore we do not consider "-8" in the domain of the function.

But for the other values, there is no problem since the denominator cannot be zero without x = -8.

Sam's rationale for the third step based on logarithm properties would be logb(b^x+y), power rule of exponents. Thus, the correct answer is C.

The first step of Sam's proof is to show that logb(MN) is equal to logb(b^x.b^y), which is a substitution of MN for b^x.b^y. This is based on the product property of logarithms, which states that logb(MN) = logb(M) + logb(N) for any positive numbers M and N and any base b, as long as b doesn't equal 1.

The third step of her proof is to simplify logb(b^x.b^y) further by applying the power rule of exponents, which states that:

So, by substituting b^(x+y) for b^x.b^y, we get:

So, in short, the justification of the third step is based on the power rule of exponents, and it shows that logb(b^x.b^y) can be simplified further to logb(b^x+y).
