Answer: B (-2)
Step-by-step explanation:
[log base b of a = c] turns into [b^c = a]
You have log base 5 of 1/25 = ?, so it turns into 5^? = 1/25
This part is sort of guess and check, but we can look at it to find the answer pretty easily. First, it's 1/n, so we should use a negative power: 5^-1 = 1/5
In addition to being in the denominator, it's 25, which is 5^2.
So, if we want to put it in a reciprocal as well as square it, we can use -2:
5^(-2) = 1/(5^2) = 1/25
Since -2 (B) is the exponent we place on 5 to get 1/25, it is also the answer to log base 5 of 1/25.
-3x<18
x> -6 ( it’s x is greater than/ less -6 than I just don’t know how to do that symbol)
Well, somehow the guests at 13/55th's more sandwiches that were present. Did you type the fractions correctly?
Answer:
2. Marta’s and Jeremiahs equations are equivalent
3. The terms are: 450n, -350n, 650, 50 and 70n
The coefficients are 450, -350 and 70
Answer:
522
Step-by-step explanation:
Find the percent of students in her class that have a dog or cat:
- Set up a proportion:
- Cross multiply, then divide: 18 × 100 = 1800, 1800 ÷ 30 = 60
- So, 60% have a dog or cat
Find 60% of the total amount of students in Monique's school:
- 60% of 870 =
× 
- ×
I hope this helps!
