4 0

Answer:

1360

Step-by-step explanation:

First, you do all the operations inside the parenthesis, and then you multiply the two. Also, remember the order of operations. Multiplication always comes before addition and subtraction.

(2.5x10-8)(9x10-10)

(25 - 8)(90 - 10)

(17)(80) = 17x80 = 1360

What value of c is the rational expression below equal to zero? x-4/x-6
RSB [31]

Answer: x=4

Steps: (I am assuming your question has a typo in it and by "c" you meant "x")

The rational expression equals zero

\frac{x-4}{x-6}=0

only when the numerator equals 0 (the denominator cannot ever be zero):

x-4 = 0 \\x = 4

and that happens only for x=4

Hoochie [10]

Answer:

15x + 15

Step-by-step explanation:

Combine like terms. Like terms are terms with the same amount of variables. Set the equation so that the terms are grouped:

6x + 9x + 6 + 9

Combine like terms:

(6x + 9x) = 15x

(6 + 9) = 15

15x + 15 is your answer.

Suppose Marcus invests $750 at an annual rate of 6.25%. How long will it take until Marcus earns $125 in simple interest?
Naddik [55]
We know, S.I. = P * R * T / 100
Here, S.I. = 125
P = 750
r = 6.25

Substitute into the formula:
125 = 750*6.25*t / 100
4687.5 * t = 12500
t = 12500 / 4687.5
t = 2.67
t = 2 2/3

In short, Your Answer would be 8/3 Years

Hope this helps!
