Hey there!

Here is your question -

$n+12=4$

In this equation, you're looking for n alone. To keep the variable alone, you have to do the opposite of what's happening to the variable.

In this equation, 12 is being added to n. The opposite of that is subtracting 12.

Subtract 12 from both sides -

$n+12-12=4-12 \\ n=-8$

Your answer is -8.

Hope this helps! :)

Fofino [41]

The amount John have left after purchase is $10.8.

<h3 /><h3>Amount John have left</h3>

John earned $45.90 during the summer break.

He used 1 / 6 of the money to buy trading card. Then he used the following amount to buy the trading card.

1 / 6 × 45.90 = $7.65

Then, he used 3/5 of the remaining amount to buy a sketchbook, and also spends $4.50. Therefore, the total he spends can be computed as follows:

3 / 5 × (45.90 - 7.65) + 4.50 = 22.95 + 4.50 = $27.45

So, He spent

$7.65 on trading cards
$22.95 on sketch book
$4.50 on comic book.

The amount he has left = 45.90 - 7.65 - 22.95 - 4.50 = $10.8

Determine the amplitude (A), period (P), and phase shift (PS) of the function f(x)= 3sin(x-4)+9

Tpy6a [65]

ANSWER

D.
$A=3,P=2\pi,PS=(4,9)$

EXPLANATION

The given function is

$f(x) = 3 \sin(x - 4) + 9$

Comparing to the general form of a trigonometric sine function,

$f(x) = A \sin(Bx-C)+D$

$A=3$
The amplitude is absolute value of A

$|A| = |3| = 3$

$B=1$

The period is given by

$p = \frac{2\pi}{ B}$

$p = \frac{2\pi}{ 1} = 2\pi$

$C=4$

is a shift to the right of 4 units.

and

$D=9$

is an upward shift of 9 units

Therefore the phase shift is (4,9).

The correct answer is D

How do I solve 1 and 1 half in to percent

Mrac [35]

Answer:

150%

Step-by-step explanation

we already know that 1 is going to be the whole so it will be 100%. Then, we will automatically know that if 1 is 100, then 1/2 is 50. If we do not know this right away we can solve for 1/2 = 100/200 = 50/100.

Our answer is 150%.
