What represents the algebraic expression 3 p + 6 Over 7 p minus 9

1 answer:

7 0

The answer is the sum of three times a number and six, divided by the difference of seven times a number and nine.

The phrase is(3p+6)/(7p-9)
Let’s describe each factor:
3p is three times a number
7p is seven times a number

3p+6 is the sum of three times a number and six
7p-9 is the difference of seven times the number and nine

The last two factors are divided, so
(3p+6)/(7p-9) is the sum of three times a number and six, divided by the difference of seven times the number and nine.

I hope this helped and have a nice day!

The sum of Joy's age and her brother's age is 24. Joy's brother's age is 3 years older than twice joy's age. What is the differe

enyata [817]

Let Joy be x years old

Joy's brother's age is 3 years older than twice joy's age.
Joy's Brother = 2x + 3

The sum of Joy's age and her brother's age is 24.
x + 2x + 3 = 24
3x + 3 = 24
3x = 24 - 3
3x = 21
x = 21 ÷ 3
x = 7

Joy:
x = 7

Brother:
2x + 3 = 2(7) + 3 = 17

Difference in their age = 17 - 7 = 10 years

They are 10 years apart.

Anybody know the right answer?

Dmitry_Shevchenko [17]

If we just have

$y = \cos x$

that's an amplitude of 1 and a period of $2\pi$

Let's modify this step by step.

Amplitude of 4. Four times the amplitude means a factor of 4 on the outside.

$y = 4 \cos x$

Period of π. Double the period means a factor of 2 on the inside.

$y = 4 \cos(2x)$

Horizontal shift of π/2 to the left. To the left means adding a positive number to x. The question appear ambiguous. It's not clear to me if we add to x or 2x; let's make it

$y = 4 \cos(2(x + \frac \pi 2))$

Vertical shift of 3:

$y = 3 + 4 \cos(2(x + \frac \pi 2))$

$y = 3 + 4 \cos(2x + \pi)$

Depending on the interpretation of the phase shift, that pi may be a pi/2.

Answer: $3 + 4 \cos(2x + \pi)$

The simplified form of 0.02(0.06+0.008)is

kramer

Answer:

Step-by-step explanation:

Use PEDMAS. So first addition has to be done as it is inside parenthesis. After that multiplication has to be done

0.060 +

0.008

0.068

In decimal multiplication, first multiply the numbers ie, 2 * 68 which is 136. Then count the number of decimal places in both the multiplicands and keep the same number of decimal places in the result(136).

0.02 * 0.068 = 0.00136
