The equation A = p + prt is used to find the accumulated amount, A, of an investment with principal, P, a certain interest rate, r, and over time, t. What is the value for r, after the equation is rearranged?r equals start fraction cap a plus p over p t end fraction
r equals start fraction cap a minus p over p t end fraction
r equals start fraction cap a minus one over t end fraction
r = A − p − pt

Answers

Answer 1

Answer: A=p+prt
minus p both sides
A-p=prt
divide both sides by pt
$(A-p)/(pt)=r$
dunno what a fraction cap is
I would guess it is the 2nd one

Answer 2

Answer:

Answer:

The answer is B, r = "A - p / pt."

Graph the following equation using the slope intercept method 3x+5y=-15

Please help I asked this question earlier and nobody answered! :(

Answers

Answer:

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form. That form is usually written $y=mx+b$ where m is the slope and b is the y-intercept.

Solve the first equation for y.

$6x+2y=5 \n 2y=-6x+5 \n y=-3x+5/2$

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

$y+3x=2\ny=-3x+2$

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.

-98 is answer If -98 is divided by 7 -98/7 = -14 We get -14 Which is 6 less than -8 As, -8 - 6 = -14

What is the next value 4d 7g 10j 13

Answers

13m 16p

Add three to every number next as well as move up three letters.

For example:
1A is the starting point.
To get from 1A to 4D you add three.

1 + 3 = 4
A to get to D is three letters up.
A b c D

Same thing for 4D to get to 7G.

4 +3 = 7
D to get to G
D e f G

Your answer:
I'm not sure if you wanted me to find the letter of the equation or the actual next part. On your question you have just 13 up there, no letter so if youre trying to find the letter (13m) is your answer.

If you're trying to find the next equation to the puzzle (16p) is your answer.

3 3\10 divided by 1 4\7

Answers

Answer:

First, let's convert the mixed numbers into improper fractions:

3 3/10 = (3 * 10 + 3)/10 = 33/10

1 4/7 = (1 * 7 + 4)/7 = 11/7

Now, we can divide the two fractions:

33/10 ÷ 11/7

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 11/7 is 7/11.

So, the division becomes:

33/10 * 7/11

Next, multiply the numerators (top numbers) together and the denominators (bottom numbers) together:

(33 * 7) / (10 * 11) = 231/110

Finally, simplify the fraction, if possible. In this case, we can divide both the numerator and denominator by their greatest common divisor, which is 11:

231/110 = (231 ÷ 11)/(110 ÷ 11) = 21/10

Therefore, 3 3/10 divided by 1 4/7 is equal to 21/10.
