Answer:
a) x = 13
b) x = 7
Step-by-step explanation:
A) Since they have the same base of 2 so
x + 4 + (-5) = 12
x - 1 = 12
x = 13
b) Since they have the same base of -3 so
8 + x + 4 = 19
x + 12 = 19
x = 7
6x-y=3 this is the equation in standard form
if Camille spent 19.40$ LESS than DOUBLE what Olivia spent then a rough estimate already can be Olivia spent 100 and Camille spent 172 but to find this out we have to add 19.40 onto 272.35 = 291.75 then we now that 291.75 is thrice what Olivia spent so if we third it we know what Olivia spent so 291.75/3 = 97.25 leaving 194.50 then if we minus 19.40 off 194.50 we get 175.10 so:
Camille spent: 175.10 and
Olivia Spent: 97.25
The answer is 1800 you take .06 being the cost of every sq yard and multiply it by 300 being the amount of sq yards
First, we are going to find the common ratio of our geometric sequence using the formula:

. For our sequence, we can infer that

and

. So lets replace those values in our formula:


Now that we have the common ratio, lets find the explicit formula of our sequence. To do that we are going to use the formula:

. We know that

; we also know for our previous calculation that

. So lets replace those values in our formula:

Finally, to find the 9th therm in our sequence, we just need to replace

with 9 in our explicit formula:



We can conclude that the 9th term in our geometric sequence is <span>
