Hi there!
With exponents, there are a few things to keep in mind:
1. Do <u>not </u>multiply the base by the exponent (the base is the number that has an exponent; for example, 3 is the base of 3^2)
2. On the computer, exponents are signaled by this sign ^.
3. The exponent is the number of times you multiply the base by itself
Let's say you're given this exponent : 6^3
Because the exponent is 3, we need to multiply 6 by 6 a total of 3 times. It's tricky, but here's how you do it:
(6 * 6) * 6
36 * 6 = 216
So, 6^3 is 216
Here's another example:
9^5
(9*9) * 9* 9* 9
[81 * 9]*9 *9
[729 * 9] * 9
6561 * 9
59049
Answer:
Alana is 13 years old.
Step-by-step explanation:
Assuming you meant Mazo = Maisel,
You start from the bottom:
Amelia is 10 years younger than 17-year-old Maisel.
Amelia is 7 years old. (17-10)
Ernie is 2 years older than 7-year-old Amelia.
Ernie is 9. (2+7)
Alana is 4 years older than 9-year-old Ernie.
Alana is 13 years old. (4+9)
Hope this helps!

Your answer should be 12.73
Determine which of the four possible answer graphs features the lines
<span> s + l < 30 and
and
8s + 12l ≤ 160 This one could be reduced to s+1.5l</span>≤20
Note that the first equation has s-intercept 30 and l intercept 30.
Also, that the send equation has s-intercept 20 and l intercept 13 1/3.
Knowing these intercepts will help you to recognize the properly graphed lines.
So, again, determine from this info which of the four possible answer graphs correctly illustrates the lines mentioned immediately above.
