Answer:

125-x

Step-by-step explanation:

i don't know what exactly you're aiming for, but if you want to write this as an equation, you would put it as 125-x. since we don't know what the number is, we would put a variable that we can sub in any number we want.

hope this made sense!

The phrase "decreased by" means subtraction. Also whenever you see "a number", you can think of x. So we have 125 - x is the answer. Just be careful in this section, the terms "from" and "less than" will require you to change the order that you see in the question. For us, the phrase was "decreased by" so we didn't need to change the order. The 125 was in front and the "number" was in the back. EXTRA: "125 from a number" would be x - 125 because you would have to switch the order.

If a borrower's monthly interest payment on an interest-only loan at an annual interest rate of 7.3% is $877, how much was the l
nordsb [41]

Answer:

C. $144,200

Step-by-step explanation:

We have been given that a borrower's monthly interest payment on an interest-only loan at an annual interest rate of 7.3% is $877.

To find the loan amount, we will use simple interest formula.

I=Prt, where,

I = Amount of interest,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

One month will be equal to 1/12 year.

7.3\%=\frac{7.3}{100}=0.073

Upon substituting our given values in simple interest formula, we will get:

877=P*0.073*\frac{1}{12}

877*12=P*0.073*\frac{1}{12}*12

10524=P*0.073

P*0.073=10524

\frac{P*0.073}{0.073}=\frac{10524}{0.073}

P=144164.3835616438356

Upon rounding to nearest hundred, we will get:

P\approx 144,200

Therefore, the loan amount was $144,200 and option C is the correct choice.

3 (6+3n) = 5n + 18 + 3n
amid [387]

Answer:

n = 0

Step-by-step explanation:

Multiply parenthesis by 3 and get:

1.) 18 + 9n = 5n + 18 + 3n

Then cancel the equal terms:

9n = 5n + 3n

Collect like terms:

9n = 8n

Move variable to the left:

9n - 8n = 0

n + 0

Plugin the value of 0 into x:

3 (6 + 3 x 0) = 18

5 x 0 + 3 x 0 + 18 = 18

*If the plugged in value have the same result than the answer is correct because 18 + 18.

What is the equation of the perpendicular bisector of the segment joining points A(1, 1) and B(5, 7)?
Elden [556K]
Bisector must pass through the mid-point, so we have to find out that mid-point of the segment:

mid point = x₁+x₂ / 2 , y₁+y₂/2
= 1 + 5 / 2 , 1 + 7 / 2
= 6/2 , 8/2
= (3, 4)

Slope of given segment = m = y₂-y₁ / x₂- x₁
m = 7-1 / 5-1
m = 6/4
m = 3/2

Now, segment which is perpendicular, will have the opposite & reciprocal slope, So, it would be: -2/3

We know, y - y₁ = m(x - x₁)
y - 4 = -2/3(x - 3)
y - 4 = -2/3x + 2
y = -2/3x + 6

In short, Your Final Answer would be: y = -2/3x + 6

Hope this helps!
