Answer:
Sally is currently 4 years old.
Step-by-step explanation:
<em>Kaden is 18 years older than Sally now. In 5 years, Kaden will be 3 times as old as Sally. How old is Sally now?</em>
<em />
Let Kaden's current age be and Sally's current age be . We can write the following algebraic equation using the fact that Kaden is currently 18 years older than Sally:
Next, we will use the fact that in 5 years, Kaden will be 3 times as old as Sally. If Kaden and Sally's current ages are and respectively, then their ages in 5 years will be and respectively. Therefore, we have:
We have two equations with two variables. To solve for either variable, we need to create an equation with only one variable. Therefore, let's substitute the first equation into the second:
Distribute and combine like terms:
Subtract from both sides, then subtract 15 from both sides:
Divide both sides by 2:
Therefore, Sally is currently 4 years old.

the answer is:
78.7 (i rounded it to the nearest tenth)
Answer:
correct option is C. 9817
Step-by-step explanation:
given data
x = 9
log(y) = 3.992
solution
we know that we have given that when x = 9
so log (y) = 3.992 .........................1
so now we take here anti log on the both side of given equation that is
put the value of antilog in equation 1 we get
y =
solve it we get y that is
y = 9817.47
y = 9817
so correct option is C. 9817
I believe it will be D) 22. I say this because if you:
88/8 = 11 bags
66/6 = 11 bags
When you add them up, you get 22
