The answer to you question is B
Answer:
9(n + 22) ≤ -15
Step-by-step explanation:
9 times the sum of a number and 22 is at most −15
Let n = number
Times = multiplication
Sum = Addition
9 * n + 22
We must add parenthesis on the end on 22 and before n
We must do this because it says 9 times the sum of a number and 22 which means that 9 is being multiplied by both n and 22
We would have 9(n + 22)
9(n + 22) is at most -15
At most meaning that -15 is the highest number that 9(n + 22) can equal
Because it says at most 9(n + 22) can equal -15 or anything less than -15
So at most can be replaced with ≤
9(n + 22) ≤ -15

Answer:
See below
Step-by-step explanation:
I believe that you only had to do letters F, H, and J. In that case, let's go over each one!
F: For isolating
, we need to get rid of the 1/2 first. Let's multiply each side by 2:

After this, we just subtract
from each side to get
. Dark Blue is correct! Let's now plug in those numbers below:

G: Let's isolate the vw^2 on one side by subtracting y from each side:

Let's now divide each side by v, then put each side under a square root to get our final answer:

Orange is correct! Again, let's solve the problem underneath:
w=
H: This one has some stuff that we haven't worked with quite yet (like terms), but our approach is the same: isolate c on one side of the equation.

Purple is correct! Let's solve the problem:

Answer: 10.53%
Step-by-step explanation:
George £89400 @ 9% = £8046 so income = £89400+£8046=£97446
Harris (Paris?) gets £447 more so 97446+447=£97893
and this represents sales of £89400 plus commission
so Harris' commission = £97893-£89400 = £8493
So last stage is what commission percentage is £8493 of original sales £89400 = 10.53%
